What is (are) Gilbert syndrome ?
|
Gilbert syndrome is a common, mild liver disorder in which the liver doesn't properly process bilirubin, a substance produced by the breakdown of red blood cells. Gilbert syndrome typically doesn't require treatment or pose serious complications. In fact, Gilbert syndrome is usually not considered a disease because of its benign nature. Many individuals find out they have the disorder by accident, when they have a blood test that shows elevated bilirubin levels. More males than females have been diagnosed with Gilbert syndrome. This condition is caused by mutations in the UGT1A1 gene and is inherited in an autosomal recessive pattern.

What are the symptoms of Gilbert syndrome ?
|
What are the signs and symptoms of Gilbert syndrome? While many people with Gilbert syndrome never experience any symptoms, mild jaundice may occur if bilirubin levels get high enough. Other possible symptoms may include fatigue, weakness and abdominal pain. Patients may have more side effects from certain drugs such as irinotecan. The Human Phenotype Ontology provides the following list of signs and symptoms for Gilbert syndrome. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Abnormality of the liver 90% Abdominal pain 50% Nausea and vomiting 50% Reduced bone mineral density 7.5% Autosomal recessive inheritance - Jaundice - Unconjugated hyperbilirubinemia - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.

Is Gilbert syndrome inherited ?
|
How is Gilbert syndrome inherited? Gilbert syndrome is inherited in an autosomal recessive manner, which means both copies of the gene in each cell have mutations. The parents of a person with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

What are the treatments for Gilbert syndrome ?
|
How might Gilbert syndrome be treated? Gilbert syndrome generally doesn't require treatment. The bilirubin levels in the blood may fluctuate over time, causing episodes of jaundice. However, the jaundice is usually mild and goes away on its own. In some cases, doctors may prescribe phenobarbital to lower extremely elevated bilirubin levels and reduce signs of jaundice. Phenobarbital administration usually alleviates signs of jaundice fairly quickly.

What is (are) Annular atrophic lichen planus ?
|
Annular atrophic lichen planus (LP) is a rare form of lichen planus, which is a condition that affects the skin and/or mouth. In annular atrophic LP, specifically, affected people develop skin lesions with features of both annular LP and atrophic LP - ring-shaped, slightly raised, purple lesions with central atrophy (tissue breakdown). Although these lesions can be found anywhere on the body, they most commonly affect the trunk and legs. The exact underlying cause of annular atrophic LP is unknown. Treatment is not always necessary as some cases of annular atrophic LP resolve on their own. Mild cases that are diagnosed early can often be managed with topical steroids, while more intensive therapies may be required for severe cases.

What is (are) Bilateral perisylvian polymicrogyria ?
|
Bilateral perisylvian polymicrogyria (BPP) is a rare neurological disorder that affects the cerebral cortex (the outer surface of the brain). Signs and symptoms include partial paralysis of muscles on both sides of the face, tongue, jaws, and throat; difficulties in speaking, chewing, and swallowing; and/or seizures. In most cases, mild to severe intellectual disability is also present. While the exact cause of BPP is not fully understood, it is thought to be due to improper brain development during embryonic growth. Most cases of BPP occur sporadically in people with no family history of the disorder; however, more than one family member may rarely be affected by the condition. Treatment is based on the signs and symptoms present in each person.

What causes Bilateral perisylvian polymicrogyria ?
|
What causes bilateral perisylvian polymicrogyria? The exact underlying cause of bilateral perisylvian polymicrogyria (BPP) is unknown. The signs and symptoms associated with the condition are thought to be due to improper development of the outer surface of the brain (cerebral cortex) during embryonic growth. The cerebral cortex, which is responsible for conscious movement and thought, normally consists of several deep folds (gyri) and grooves (sulci). However, in people affected by BPP, the cerebral cortex has an abnormally increased number of gyri that are unusually small. Scientists believe that these abnormalities occur when newly developed brain cells fail to migrate to their destined locations in the outer portion of the brain. Specific non-genetic causes of polymicrogyria have been recognized, including exposure to cytomegalovirus infection (CMV) during pregnancy. Polymicrogyria has also been associated with certain complications in twin pregnancies.

What is (are) Prosthetic joint infection ?
|
A prosthetic joint infection (PJI) is a rare complication of joint replacement surgery, also known as arthroplasty. Arthroplasty is done to help relieve pain and restore function in a severely diseased joint, such as a knee, hip or shoulder. Approximately 0.5 to 1 percent of people with replacement joints develop a PJI. Infections can occur early in the course of recovery from joint replacement surgery (within the first two months) or much later. Signs and symptoms of PJI include fever, chills, drainage from the surgical site, and increasing redness, tenderness, swelling and pain of the affected joint. Prosthetic joint infections are often hard to treat because of the development of a structure called a biofilm within the joint. A biofilm develops when bacteria adhere to the solid surface of the artificial joint. The biofilm can act as a kind of shield to some of the bacteria, making it difficult for the bacteria to be found and destroyed by the body's defenses or by antibiotic medications. An infected joint replacement usually requires surgery to remove the artificial parts and potent antibiotics to kill the bacteria.

What is (are) Myoclonic epilepsy with ragged red fibers ?
|
Myoclonic epilepsy with ragged red fibers (MERRF) is a multisystem disorder characterized by myoclonus, which is often the first symptom, followed by generalized epilepsy, ataxia, weakness, and dementia. Symptoms usually first appear in childhood or adolescence after normal early development. The features of MERRF vary widely from individual to individual, even within families. Other common findings include hearing loss, short stature, optic atrophy, and cardiomyopathy with Wolff-Parkinson-White (WPW) syndrome. The diagnosis is based on clinical features and a muscle biopsy finding of ragged red fibers (RRF). In over 80% of cases, MERRF is caused by mutations in the mitochondrial gene called MT-TK. Several other mitochondrial genes have also been reported to cause MERRF, but many of the individuals with mutations in these other genes have additional signs and symptoms. Seizures associated with MERRF are generally treated with conventional anticonvulsant therapy. Coenzyme Q10 and L-carnitine are often used with the hope of improving mitochondrial function.

What are the symptoms of Myoclonic epilepsy with ragged red fibers ?
|
What are the signs and symptoms of Myoclonic epilepsy with ragged red fibers? Because muscle cells and nerve cells have especially high energy needs, muscular and neurological problems are common features of diseases that affect the mitochondria. MERRF is a progressive multi-system syndrome with symptoms that begin during childhood, but onset may occur in adulthood. The rate of progression varies widely. Onset and extent of symptoms can differ widely from individual to individual and among affected siblings. The classic features of MERRF include: Myoclonus (brief, sudden, twitching muscle spasms) the most characteristic symptom Epileptic seizures Ataxia (impaired coordination) Ragged-red fibers (a characteristic microscopic abnormality observed in muscle biopsy of patients with MERRF and other mitochondrial disorders) Additional symptoms may include: hearing loss, lactic acidosis (elevated lactic acid level in the blood), short stature, exercise intolerance, dementia, cardiac defects, eye abnormalities, and speech impairment. However, the exact symptoms aren't the same for everyone, because a person with mitochondrial disease can have a unique mixture of healthy and non-working mitochondria, with a unique distribution in the body. Despite their many potential effects, mitochondrial diseases sometimes cause little disability. Sometimes, a person has enough healthy mitochondria to compensate for the defective ones. The Human Phenotype Ontology provides the following list of signs and symptoms for Myoclonic epilepsy with ragged red fibers. If the information is available, the table below includes how often the symptom is seen in people with this condition.

|
Is Myoclonic epilepsy with ragged red fibers inherited ?
|
Is myoclonic epilepsy associated with ragged red fibers genetic? If so, how is it inherited? MERRF is caused by mutations in the mitochondrial DNA and is transmitted by maternal inheritance. It is called maternal inheritance because a child inherits the great majority of their mitochondria from their mother through the egg. The Centre for Genetics Education provides a detail description of maternal inheritance. The mother of an individual with MERRF usually has a mitochondrial mutation and may or may not have symptoms. Or, an individual with MERRF may have a mitochondrial mutation that just occurred in them, called a de novo mutation. If the mother has the mitochondrial mutation, all of her children will inherit the mutation and may or may not have symptoms. All of her daughters children will also inherit the mitochondrial mutation. Her son's children are not at risk of inheriting the mutation.

What is (are) Myotonic dystrophy ?
|
Myotonic dystrophy is an inherited condition that affects the muscles and other body systems. It is the most common form of muscular dystrophy that begins in adulthood, usually in a person's 20s or 30s. This condition is characterized by progressive muscle loss and weakness, particularly in the lower legs, hands, neck, and face. People with myotonic dystrophy often have prolonged muscle tensing (myotonia) and are not able to relax certain muscles after use. The severity of the condition varies widely among affected people, even among members of the same family. There are two types of myotonic dystrophy: myotonic dystrophy type 1 and myotonic dystrophy type 2. The symptoms in people with myotonic dystrophy type 2 tend to be milder than in those with type 1. Although both types are inherited in an autosomal dominant pattern, they are caused by mutations in different genes. Myotonic dystrophy type 1 is caused by mutations in the DMPK gene, while type 2 is caused by mutations in the CNBP gene.

What are the symptoms of Myotonic dystrophy ?
|
What are the signs and symptoms of Myotonic dystrophy? Signs and symptoms of myotonic dystrophy often begin in a person's 20s or 30s, but they can begin at any age. Symptoms often include progressive muscle weakness and wasting (particularly in the legs, hands, neck and face); stiffness and tightness of the muscles; cataracts; and cardiac conduction defects (irregular electrical control of the heartbeat). Some affected men also have hormonal changes that may cause balding or infertility. The severity of symptoms can vary widely among affected people. The signs and symptoms of type 1 and type 2 overlap, but type 2 is generally more mild than type 1. People who are born with the condition have congenital myotonic dystrophy, which is a variation of type 1. Congenital myotonic dystophy causes weakness of all muscles, in addition to breathing problems, developmental delays and intellectual disabilities. The Human Phenotype Ontology provides the following list of signs and symptoms for Myotonic dystrophy. If the information is available, the table below includes how often the symptom is seen in people with this condition.

What causes Myotonic dystrophy ?
|
What causes myotonic dystrophy? Myotonic dystrophy is caused by mutations called nucleotide repeat expansions in either the DMPK gene (in type 1) or the CNBP gene (in type 2). Nucleotide repeat expansions occur when a piece of DNA is abnormally repeated a number of times, which makes the gene unstable. In myotonic dystrophy, the gene instability leads to a series of events that ultimately prevent cells in muscles and other tissues from acting normally, leading to the features of the condition. The exact functions of these genes in not well understood. The DMPK gene may play a role in communication within cells, specifically in cells of the heart, brain, and skeletal muscles. The CNBP gene gives directions to make a protein found mainly in cells of the heart and skeletal muscles, where it is thought to regulate the activities of other genes.

What are the treatments for Myotonic dystrophy ?
|
What treatment is available for for myotonic dystrophy? There is currently no cure or specific treatment for myotonic dystrophy. Treatment is aimed at managing symptoms and minimizing disability. Routine physical activity appears to help maintain muscle strength and endurance and to control musculoskeletal pain. Canes, braces, walkers and scooters can help as muscle weakness progresses. There are also medications that can lessen the myotonia. Pain management can be achieved through the use of mexilitene, gabapentin, nonsteroidal anti-inflammatory drugs (NSAIDS), low-dose thyroid replacement, low-dose steroids (prednisone), and tricyclic antidepressants. Other symptoms of myotonic dystrophy can also be treated. Heart problems should be followed by a cardiologist, but may be managed through insertion of a pacemaker and regular monitoring of cardiac function. Cataracts can be surgically corrected.

What is (are) Spinocerebellar ataxia 11 ?
|
Spinocerebellar ataxia type 11 (SCA11) is characterized by progressive cerebellar ataxia (difficulty walking and balance) and abnormal eye signs (jerky pursuit, horizontal and vertical movements (nystagmus), pyramidal features (increased muscular tonus, increased reflexes and an abnormal reflex known as Babinski sign and inability to make to perform fine movements), peripheral neuropathy with numbness, weakness or pain in the feet or hands or other places of the body and dystonia. It is a very rare disease and very few patients have been reported to date. In them, age of onset ranged from the early teens to the second decade of life and life span was normal. Diagnosis is based on signs and symptoms and with a genetic exam showing an alteration (mutation) in the TTBK2 gene. It is inherited in an autosomal dominant manner. Treatment may include speech and language therapy for talking and swallowing problems, occupational therapy, including home adaptations, physiotherapy and use of assistive walking devices and ankle-foot orthotics (AFOs) for those with neuropathy.

Is Spinocerebellar ataxia 11 inherited ?
|
How is spinocerebellar ataxia type 11 inherited? SCA11 is inherited in an autosomal dominant manner. The rate of de novo mutations is not known. Each child of an individual with SCA11 has a 50% chance of inheriting the mutation. Prenatal diagnosis for at-risk pregnancies is possible if the diagnosis has been confirmed by molecular genetic testing in a parent. Each child of an individual with SCA11 has a 50% chance of inheriting the mutation. Genetic testing of adults who do not have any symptoms but are at-risk of having inherited the mutation is possible. However, testing is not useful in predicting age of onset, severity, type of symptoms, or rate of progression in individuals who do not have any symptom. The affected family member should be tested first to confirm the molecular diagnosis in the family. The best person who can answer questions and address any concerns about inheritance questions is a genetic professional. To find a genetics clinic, we recommend that you contact your primary healthcare provider for a referral.

What is (are) Chromosome 2q deletion ?
|
Chromosome 2q deletion is a chromosome abnormality that occurs when there is a missing copy of the genetic material located on the long arm (q) of chromosome 2. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved. Features that often occur in people with chromosome 2q deletion include developmental delay, intellectual disability, behavioral problems, and distinctive facial features. Most cases are not inherited, but people can pass the deletion on to their children. Treatment is based on the signs and symptoms present in each person.

What is (are) Idiopathic inflammatory myopathy ?
|
Idiopathic inflammatory myopathy refers to a group of conditions that affect the skeletal muscles (muscles used for movement). Although the condition can be diagnosed at any age, idiopathic inflammatory myopathy most commonly occurs in adults between ages 40 and 60 years or in children between ages 5 and 15 years. Signs and symptoms of the condition include muscle weakness, joint pain and fatigue. There are several forms of idiopathic inflammatory myopathy, including polymyositis, dermatomyositis, and sporadic inclusion body myositis, which are each associated with unique features. As the name suggests, the cause of the condition is currently unknown (idiopathic). However, researchers suspect that it may occur due to a combination of genetic and environmental factors. Treatment is supportive and based on the signs and symptoms present in each person.

What is (are) Familial atrial fibrillation ?
|
Familial atrial fibrillation is an inherited heart condition that disrupts the heart's rhythm. It is characterized by erratic electrical activity in the heart's upper chambers (the atria), causing an irregular response in the heart's lower chambers (the ventricles). This causes a fast and irregular heartbeat (arrhythmia). Signs and symptoms may include dizziness, chest pain, palpitations, shortness of breath, or fainting. Affected people also have an increased risk of stroke and sudden death. While complications may occur at any age, some affected people never have associated health problems. Familial atrial fibrillation may be caused by changes (mutations) in any of various genes, some of which have not been identified. It is most often inherited in an autosomal dominant manner, but autosomal recessive inheritance has been reported.

What are the treatments for Familial atrial fibrillation ?
|
How might familial atrial fibrillation be treated? We are unaware of treatment recommendations specific to familial atrial fibrillation, but there is information available about treatment for atrial fibrillation in general. Treatment for atrial fibrillation depends on the frequency and severity of symptoms and may involve medications, medical procedures, and lifestyle changes. People who don't have symptoms or related heart problems may not need treatment. The main goals of treatment include: Preventing blot clots and lowering risk of stroke. This may involve blood-thinning medications such as warfarin, dabigatran, heparin, and aspirin. Controlling the rate of contractions of the ventricles (rate control). This may involve medications to restore the heart rate to a normal level, such as beta blockers, calcium channel blockers, and digitalis. Restoring a normal heart rhythm (rhythm control). This is typically for people who don't do well with rate control treatment, or for people who recently began having symptoms. Rhythm control may involve medications or procedures and is usually begun in a hospital for monitoring. Procedures may include cardioversion, catheter ablation, or maze surgery.

What is (are) Hereditary mucoepithelial dysplasia ?
|
Hereditary mucoepithelial dysplasia (HMD) is a condition that affects the skin, hair, mucosa (areas of the body that are lined with mucus), gums (gingiva), eyes, nose and lungs. Symptoms typically begin in infancy and may include development of cataracts (clouding of the eye lens); blindness; hair loss (alopecia); abnormal changes to the perineum (the area between the anus and external genitalia); and small, skin-colored bumps (keratosis pilaris). Terminal lung disease has also been reported. The cause of HMD is thought to be an abnormality in desmosomes and gap junctions, which are structures involved in cell-to-cell contact. HMD typically follows autosomal dominant inheritance, but has occurred sporadically (in an individual who has no family history of the condition). Treatment typically focuses on individual symptoms of the condition.

What is (are) Charcot-Marie-Tooth disease type 1E ?
|
Charcot-Marie-Tooth disease type 1E (CMT1E) is a form of Charcot-Marie-Tooth disease, which is a group of rare conditions that affect the peripheral nerves. Signs and symptoms of CMT1E generally become apparent between age 5 and 25 years, although the age of onset and disease severity can vary significantly from person to person. In general, CMT1E is associated with the typical features of Charcot-Marie-Tooth disease type 1 (progressive weakness of the feet and/or ankles; foot drop; atrophy of muscles below the knee; absent tendon reflexes of upper and lower extremities; and a decreased sensitivity to touch, heat, and cold in the feet and/or lower legs) in addition to hearing loss. CMT1E is caused by certain changes (mutations) in the PMP22 gene and is inherited in an autosomal dominant manner. Treatment is based on the signs and symptoms present in each person.

What is (are) Eales disease ?
|
Eales disease is a rare vision disorder that appears as an inflammation and white haze around the outercoat of the veins in the retina. This condition is most common among young males and normally affects both eyes. In most cases, vision becomes suddenly blurred because the vitreous, the clear jelly that fills the eyeball behind the lens of the eye, seeps out. Treatment includes corticosteroids in the inflammation stage and photocoagulation in the proliferative stage of the disease. Visual prognosis is good if treatment begins early in the course of the disease.

What are the treatments for Eales disease ?
|
How might Eales disease be treated? Depending on the disease stage, treatment may involve corticosteroids (systemic or periocular) and/or immunosuppressants (azathioprine, cyclosporine). Anti-tubercular therapy has been recommended by some authors, however this treatment remains controversial. Bevacizumab (Avastin), a monoclonal antibody, is sometimes used via intravitreal injection. This medication appears to induce regression of neovascularization. Laser photocoagulation has become the treatment of choice in patients in the proliferative stage of Eales disease. Vitreoretinal surgery may be required if recurrent vitreous hemorrhage occurs. There may be other treatment options (for example, antioxidant vitamins A, C, and E) for Eales disease as well. We recommend that you discuss these and other treatment options with your partner's health-care providers. You can find relevant articles on the treatment of Eales disease through PubMed, a searchable database of biomedical journal articles.

What is (are) Aromatic L-amino acid decarboxylase deficiency ?
|
Aromatic l-amino acid decarboxylase (AADC) deficiency is an inherited condition that affects the way signals are passed between certain cells in the nervous system. Individuals affected by this condition often have severe movement disorders, abnormal eye movements, autonomic symptoms, and neurological impairment. The condition is caused by mutations in the DDC gene. It is inherited in an autosomal recessive pattern. Treatment includes a variety of medications which may result in varying levels of success in individual patients. Physical, occupational, and speech therapy may also be of benefit.

What are the symptoms of Aromatic L-amino acid decarboxylase deficiency ?
|
What are the signs and symptoms of Aromatic L-amino acid decarboxylase deficiency? Symptoms, which typically present during the first year of life, include severe developmental delay, weak muscle tone (hypotonia), muscle stiffness, difficulty moving, and involuntary writhing movements of the limbs (athetosis). This condition may also cause infants to lack energy, feed poorly, startle easily, and have sleep disturbances. Many people with AADC deficiency exprience episodes called oculogyric crises (also called "spells" or "attacks"), which are characterized by abnormal rotation of the eyeballs, extreme irritability and agitation, pain, muscle spasms, and uncontrolled movements of the head and neck.. These episodes can last for many hours and can be times of extreme concern for caregivers and family members. AADC deficiency may also affect the autonomic nervous system, which controls involuntary body processes like regulation of blood pressure and body temperature. Autonomic symptoms may include droopy eye lids (ptosis), constriction of the pupils of the eyes (miosis), inappropriate or impaired sweating, nasal congestion, drooling, reduced ability to control body temperature, low blood pressure (hypotension), gastroesophageal reflux, low blood sugar (hypoglycemia), fainting (syncope), and cardiac arrest. The signs and symptoms of AADC deficiency tend to worsen late in the day or when the individual is tired, and improve after sleep.

What is (are) Familial isolated hyperparathyroidism ?
|
Familial isolated hyperparathyroidism (FIHP) is an inherited form of primary hyperparathyroidism that is not associated with other features. The age of diagnosis varies from childhood to adulthood. In FIHP, tumors involving the parathyroid glands cause the production and release of excess parathyroid hormone, which in turn causes increased calcium in the blood (hypercalcemia). The tumors are usually benign, but a cancerous tumor can develop in rare cases. Abnormal levels of calcium cause many of the symptoms of FIHP, including kidney stones, nausea, vomiting, high blood pressure (hypertension), weakness, and fatigue. Osteoporosis often also develops. FIHP may be caused by mutations in the MEN1, CDC73 (also known as the HRPT2 gene), or CASR genes and is typically inherited in an autosomal dominant manner. In some cases, the cause is unknown. Mutations in the MEN1 and CDC73 genes cause other conditions in which hyperparathyroidism is one of many features, but some people with mutations in these genes have only isolated hyperparathyroidism. FIHP can also represent an early stage of other syndromes. Treatment for FIHP often includes surgical removal of the affected gland(s).

Is Familial isolated hyperparathyroidism inherited ?
|
How is familial isolated hyperparathyroidism inherited? Familial isolated hyperparathyroidism (FIHP) is typically inherited in an autosomal dominant manner. This means that having only one changed (mutated) copy of the responsible gene in each cell is enough to cause signs or symptoms of the condition. When a person with an autosomal dominant condition has children, each child has a 50% (1 in 2) chance to inherit the mutated copy of the gene from the affected parent.

How to diagnose Familial isolated hyperparathyroidism ?
|
How is familial isolated hyperparathyroidism diagnosed? The diagnosis of familial isolated hyperparathyroidism (FIHP) is primarily a diagnosis of exclusion. This means that it is diagnosed when no symptoms or genetic features of other forms of familial hyperparathyroidism are present. FIHP may be the only feature of another condition that is not manifesting completely, or it may be a distinct condition due to mutations in genes that have not yet been identified. Clinical exams, laboratory tests, and histological (microscopic) findings are needed before making a diagnosis of FIHP. A diagnosis of FIHP may include the findings of: hypercalcemia (defined as a serum calcium level greater than 10.5 mg/dL) inappropriately high parathyroid hormone (PTH) concentrations parathyroid adenomas exclusion of multiple endocrine neoplasia type 1 (MEN 1) and hyperparathyroidism-jaw tumor syndrome (HPT-JT) In the majority of people with FIHP, genetic mutations are not found. However, in some people, mutations in the MEN1, CASR, and CDC73 (HRPT2) genes have been reported. At this time, no gene has been associated exclusively with FIHP.

What is (are) Dominant dystrophic epidermolysis bullosa ?
|
Dominant dystrophic epidermolysis bullosa (DDEB) is a type of epidermolysis bullosa (EB), which is a group of rare inherited conditions in which the skin blisters extremely easily. DDEB is one of the milder forms of EB, although the severity is variable. Blisters may be present at birth, but typically appear during early childhood; occasionally they do not develop until later in life. Blisters often become more numerous and tend to occur over vulnerable sites such as knees, ankles, elbows and knuckles. In adulthood, they usually become less frequent and scars fade. Other signs and symptoms of DDEB may include dystrophic or absent nails, constipation, dental caries and swallowing problems. It is caused by mutations in the COL7A1 gene and is inherited in an autosomal dominant manner. Treatment typically includes treating blisters and avoiding infection.

What are the signs and symptoms of Dominant dystrophic epidermolysis bullosa? Dominant dystrophic epidermolysis bullosa (DDEB) is consivered to be a more mild form of dystrophic epidermolysis bullosa (DEB). Blistering is often limited to the hands, feet, knees, and elbows. Blistering may be relatively benign, but still heals with scarring and milia. Dystrophic nails, especially toenails, are common and loss of nails may occur. In the mildest forms, dystrophic nails may be the only characteristic noted. Blistering in DDEB often improves somewhat with age.

What causes Dominant dystrophic epidermolysis bullosa ?
|
What causes dominant dystrophic epidermolysis bullosa? Dominant dystrophic epidermolysis bullosa (DDEB) is caused by mutations in the COL7A1 gene. The COL7A1 gene provides instructions for making a protein that is used to assemble type VII collagen. Collagen gives structure and strength to connective tissues, such as skin, tendons, and ligaments, throughout the body. Type VII collagen plays an important role in strengthening and stabilizing the skin. It is the main component of structures called anchoring fibrils, which anchor the top layer of skin, called the epidermis, to an underlying layer called the dermis. COL7A1 mutations alter the structure or disrupt the production of type VII collagen, which impairs its ability to help connect the epidermis to the dermis. When type VII collagen is abnormal or missing, friction or other minor trauma can cause the two skin layers to separate. This separation leads to the formation of blisters, which can cause extensive scarring as they heal. A diagram of the skin structure including the area of skin implicated in DDEB is provided by the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Click on the link for more.

Is Dominant dystrophic epidermolysis bullosa inherited ?
|
How is dominant dystrophic epidermolysis bullosa inherited? Dominant dystrophic epidermolysis bullosa (DDEB) has an autosomal dominant pattern of inheritance. Autosomal dominant inheritance means that one copy of the gene with the mutation in each cell is sufficient to cause the disorder. About 70 percent of individuals with DDEB have inherited a COL7A1 mutation from an affected parent. The remaining 30 percent have the condition as a result of a new (de novo) mutation in the COL7A1 gene. These cases occur in people with no history of the disorder in their family. Regardless of whether an individual with an autosomal dominant condition has inherited the mutation or has a new mutation, each child of the affected individual has a 50% (1 in 2) chance of also having the condition, and a 50% chance of not having the condition.

What are the treatments for Dominant dystrophic epidermolysis bullosa ?
|
How might dominant dystrophic epidermolysis bullosa be treated? There is currently no cure for all types of dystrophic epidermolysis bullosa (DEB). Treatment generally focuses on managing signs and symptoms. For some individuals, such as those that have a mild form of dominant dystrophic epidermolysis bullosa (DDEB), dystrophic nails may be the only manifestation. However, other individuals may have much more severe problems that need to be managed. Management typically focuses on treating blisters and avoiding or treating infections. Wound care usually included treatment of new blisters by lancing and draining. Additionally in most cases, wounds are then dressed with a non-adherent material, covered with padding for stability and protection, and secured with an elastic wrap for integrity. Due to the increased risk of bacterial resistance, topical antibiotic ointments and antimicrobial dressings should be reserved for those wounds that are colonized with bacteria and fail to heal, referred to as critical colonization." Individuals with epidermolysis bullosa (EB) have increased caloric and protein needs due to the increased energy utilized in wound healing. Involvement of the digestive system in some forms of EB may limit nutritional intake. Infants and children with more severe forms of EB and failure to thrive usually require attention to fluid and electrolyte balance and may require nutritional support, including a gastrotomy feeding tube. Anemia is typically treated with iron supplements and transfusions as needed. Other nutritional supplements may include calcium, vitamin D, selenium, carnitine, and zinc. Surveillance is important for individuals with DEB. Biopsies of abnormal-appearing wounds that do not heal may be recommended in some types of DEB due to predisposition to squamous cell carcinoma, beginning in the second decade of life. Screening for deficiencies of iron, zinc, vitamin D, selenium, and carnitine is typically recommended after the first year of life. Routine echocardiograms are recommended to identify dilated cardiomyopathy, and bone mineral density studies are recommended to identify osteoporosis. Activities and bandages that may traumatize the skin (including all adhesives) should typically be avoided. Recent treatment advancements and therapies under investigation include but are not limited to: Use of biological dressings to treat chronic or recurrent skin ulcers Bone marrow transplantation Intra-dermal (in the skin) injection of fibroblasts Protein replacement therapy (intra-dermal injection of type VII collagen) Gene therapy Revertant mosaicism Gene correction technologies (ex. CRISPR) DEBRA International has developed clinical practice guidelines for different aspects of treating EB including wound care and pain management.

The nature and severity of signs and symptoms may vary, but they most often appear during infancy or early childhood and can include severe brain dysfunction (encephalopathy), cardiomyopathy, confusion, vomiting, muscle weakness, and hypoglycemia. Some individuals may only have fatigability in adulthood, or no symptoms at all. This condition is caused by mutations in the SLC22A5 gene and is inherited in an autosomal recessive manner. Treatment and prevention of symptoms typically includes oral L-carnitine supplementation.

Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.

What causes Primary carnitine deficiency ?
|
What causes primary carnitine deficiency? Mutations in the SLC22A5 gene cause primary carnitine deficiency. This gene provides instructions for making a protein called OCTN2 that transports carnitine into cells. Cells need carnitine to bring certain types of fats (fatty acids) into mitochondria, which are the energy-producing centers within cells. Fatty acids are a major source of energy for the heart and muscles. During periods of fasting, fatty acids are also an important energy source for the liver and other tissues. Mutations in the SLC22A5 gene result in an absent or dysfunctional OCTN2 protein. As a result, there is a shortage (deficiency) of carnitine within cells. This deficiency, as well as potential build-up of fatty acids within the cells, causes the signs and symptoms of the condition.

Is Primary carnitine deficiency inherited ?
|
How is primary carnitine deficiency inherited? Primary carnitine deficiency is inherited in an autosomal recessive manner. Individuals have two copies of each gene, one of which is inherited from each parent. For an individual to have an autosomal recessive condition, he/she must have a mutation in both copies of the disease-causing gene. The parents of an affected individual, who each likely have one mutated copy, are referred to as carriers. Carriers typically do not have any signs or symptoms of the condition. When two carriers for an autosomal recessive condition have children together, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier like each of the parents, and a 25% risk to not have the condition and not be a carrier.

What are the treatments for Primary carnitine deficiency ?
|
How might primary carnitine deficiency be treated? Most individuals with primary carnitine deficiency are followed by a metabolic doctor as well as a dietician familiar with this condition. Certain treatments may be advised for some children but not others. Treatment is often needed throughout life. The main treatment for this condition is lifelong use of L-carnitine, which is a natural substance that helps body cells make energy. It also helps the body get rid of harmful wastes. L-carnitine can reverse the heart problems and muscle weakness caused by this condition. In addition to L-carnitine, infants and young children with primary carnitine deficiency need to eat frequently to prevent a metabolic crisis. In general, it is often suggested that infants be fed every four to six hours. But some babies need to eat even more frequently than this. Many teens and adults with this condition can go without food for up to 12 hours without problems. Some children and teens benefit from a low-fat, high carbohydrate diet. Any diet changes should be made under the guidance of a metabolic specialist and/or dietician familiar with this condition. Ask your doctor whether your child needs to have any changes in his or her diet. Other treatments usually need to be continued throughout life. Infants and children with this condition need to eat extra starchy food and drink more fluids during any illness, even if they may not feel hungry, because they could have a metabolic crisis. Children who are sick often do not want to eat. If they wont or cant eat, they may need to be treated in the hospital to prevent serious health problems.

What is (are) Guillain-Barre syndrome ?
|
Guillain-Barr syndrome is a rare disorder in which the body's immune system attacks part of the peripheral nervous system. Symptoms include muscle weakness, numbness, and tingling sensations, which can increase in intensity until the muscles cannot be used at all. Usually Guillain-Barr syndrome occurs a few days or weeks after symptoms of a viral infection. Occasionally, surgery or vaccinations will trigger the syndrome. It remains unclear why only some people develop Guillain-Barr syndrome but there may be a genetic predisposition in some cases. Diagnosed patients should be admitted to a hospital for early treatment. There is no cure for Guillain-Barr syndrome, but treatments such as plasma exchange (plasmapheresis) and high dose immunoglobulins may reduce the severity and duration of symptoms. Recovery can take as little as a few days to as long as a few years. About 30% of those with Guillain-Barr syndrome have residual weakness. A small number may suffer a relapse many years after the initial attack.

What is (are) Pure autonomic failure ?
|
Pure autonomic failure is characterized by generalized autonomic failure without central nervous system (brain or spinal cord) involvement. The autonomic nervous system is the part of our bodies that controls involuntary actions, such as the widening or narrowing of our blood vessels. Failure of this system can cause a variety of symptoms. The most common symptom of pure autonomic failure is orthostatic hypotension. Other symptoms may include decreased sweating, heat intolerance, inability to empty the bladder, erectile dysfunction, incontinence or constipation, and pupil changes. The cause of this condition is usually unknown.

What is (are) Hereditary spherocytosis ?
|
Hereditary spherocytosis is a condition characterized by hemolytic anemia (when red blood cells are destroyed earlier than normal). Signs and symptoms can range from mild to severe and may include pale skin, fatigue, anemia, jaundice, gallstones, and enlargement of the spleen. Some people with a severe form may have short stature, delayed sexual development, and skeletal abnormalities. The condition is caused by mutations in any of several genes, such as the ANK1, EPB42, SLC4A1, SPTA1, and SPTB genes. It is most commonly inherited in an autosomal dominant manner, but may be inherited in an autosomal recessive manner. There are different types of hereditary spherocytosis, which are distinguished by severity and genetic cause. Depending on severity, treatment may involve splenectomy, red cell transfusions, folic acid supplementation, and/or cholecystectomy.

What causes Hereditary spherocytosis ?
|
What causes hereditary spherocytosis? Hereditary spherocytosis may be caused by mutations in any one of several genes. The mutations that cause the condition result in the formation of spherical, overly rigid, misshapen red blood cells. The misshapen red blood cells, called spherocytes, are removed from circulation and taken to the spleen for destruction. Within the spleen, the red blood cells break down (undergo hemolysis). The shortage of red blood cells in the blood circulation and the abundance of cells in the spleen are responsible for the signs and symptoms of this condition. Mutations in the ANK1 gene are responsible for about half of all cases of hereditary spherocytosis. The other genes associated with hereditary spherocytosis account for a smaller percentage of cases and include the EPB42, SLC4A1, SPTA1, and SPTB genes.

Is Hereditary spherocytosis inherited ?
|
How is hereditary spherocytosis inherited? About 75 percent of cases of hereditary spherocytosis are inherited in an autosomal dominant manner, which means that one copy of the altered (mutated) gene in each cell is sufficient to cause the condition. The mutated gene may be inherited from an affected parent or may occur for the first time in the affected individual. Each child of an individual with an autosomal dominant form of hereditary spherocytosis has a 50% (1 in 2) risk to inherit the mutated gene. Less commonly, hereditary spherocytosis is inherited in an autosomal recessive manner, which means that both copies of the disease-causing gene in each cell have mutations. Parents of a person with an autosomal recessive condition each carry one copy of the mutated gene and are referred to as carriers. Carriers of an autosomal recessive condition typically do not have signs and symptoms of the condition. When two carriers of the same autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have to condition, a 50% (1 in 2) risk to be a carrier like each parent, and a 25% risk to not have the condition and not be a carrier. In some of the cases that result from new mutations in people with no history of the condition in their family, the inheritance pattern may be unclear.

What is (are) Hyperprolinemia type 2 ?
|
Hyperprolinemia type 2 results in an excess of a particular protein building block (amino acid), called proline, in the blood. This condition generally occurs when proline is not broken down properly by the body. Hyperprolinemia type 2 causes proline levels in the blood to be 10 to 15 times higher than normal, and it also causes high levels of a related compound called pyrroline-5-carboxylate. Some people with this condition develop mild mental retardation and seizures; however, the symptoms of this disorder vary in severity among affected individuals.

|
How might hyperprolinemia type 2 be treated? There is no specific treatment for hyperprolinemia type 2, even for those individuals who experience seizures. In general, if people with hyperprolinemia type 2 have symptoms, they are usually mild and do not require treatment. If seizures are present during childhood, they tend to disappear in adulthood. Attempts to reduce the amount of proline in an affected person's diet have resulted in only modest control of proline levels in the blood and have not reduced symptoms.

What is (are) Axenfeld-Rieger syndrome type 2 ?
|
Axenfeld-Rieger syndrome is a group of eye disorders that affects the development of the eye. Common eye symptoms include cornea defects, which is the clear covering on the front of the eye, and iris defects, which is the colored part of the eye. People with this syndrome may have an off-center pupil (corectopia) or extra holes in the eyes that can look like multiple pupils (polycoria). About 50% of people with this syndrome develop glaucoma, which is a serious condition that increases pressure inside of the eye. This may cause vision loss or blindness. Click here to view a diagram of the eye. Even though Axenfeld-Rieger syndrome is primarily an eye disorder, this syndrome is also associated with symptoms that affect other parts of the body. Most people with this syndrome have distinctive facial features and many have issues with their teeth, including unusually small teeth (microdontia) or fewer than normal teeth (oligodontia). Some people have extra folds of skin around their belly button, heart defects, or other more rare birth defects. There are three types of Axenfeld-Rieger syndrome and each has a different genetic cause. Axenfeld-Rieger syndrome type 1 is caused by spelling mistakes (mutations) in the PITX2 gene. Axenfeld-Rieger syndrome type 3 is caused by mutations in the FOXC1 gene. The gene that causes Axenfeld-Rieger syndrome type 2 is not known, but it is located on chromosome 13. Axenfeld-Rieger syndrome has an autosomal dominant pattern of inheritance.

What is (are) Familial juvenile hyperuricaemic nephropathy ?
|
Familial juvenile hyperuricaemic nephropathy (FJHN) is an inherited condition that affects the kidneys. The signs and symptoms vary, even among members of the same family. Many individuals with this condition develop high blood levels of a waste product called uric acid. Normally, the kidneys remove uric acid from the blood and transfer it to urine. In FJHN, the kidneys are unable to remove uric acid from the blood effectively. Beginning in the early teens, FJHN causes gout and slowly progressive kidney disease, resulting in kidney failure. People with FJHN typically require either dialysis to remove wastes from the blood or a kidney transplant. FJHN is caused by mutations in the UMOD gene and is inherited in an autosomal dominant fashion.

What is (are) Weill-Marchesani syndrome ?
|
Weill-Marchesani syndrome is an inherited connective tissue disorder that mainly affects the bones and eyes. People with this condition have short stature; short fingers; and limited joint movement, especially of the hands. Weill-Marchesani syndrome also causes abnormalities of the lens of the eye that lead to severe nearsightedness, and it can also cause glaucoma. Occasionally patients with this condition have heart defects. In some families this condition is inherited in an autosomal recessive pattern and caused by mutations in the ADAMTS10 or LTPBP2 genes. Weill-Marchesani syndrome can also have autosomal dominant inheritance, and a FBN1 gene mutation has been found in one family. People with this condition usually need regular eye exams and sometimes need eye surgery.

What are the treatments for Weill-Marchesani syndrome ?
|
How might Weill-Marchesani syndrome be treated? There is no cure for Weill-Marchesani syndrome, and treatment focuses addressing the symptoms that develop. Individuals with this condition often need a team of medical specialists, including pediatricians, eye specialists (ophthalmologists and optometrists), orthopedists, and cardiologists. Regular eye exams are important for early diagnosis of eye problems. Corrective glasses, visual aids, or eye surgery may be needed to improve vision. Increased pressure within the eye (glaucoma) may be treated with eye drops, laser therapy, surgical removal of the iris or lens. Contraction or dilation of the pupils can cause glaucoma in some people with Weill-Marchesani syndrome. Medications that contract the pupil must be avoided, and medications that dilate the pupils must be given with care. Joint stiffness and bone abnormalities can cause complications if anesthesia is needed for a procedure. It is important to inform a physician of the diagnosis before receiving anesthesia, as it can impact airway management.

What are the signs and symptoms of Long QT syndrome 3? The Human Phenotype Ontology provides the following list of signs and symptoms for Long QT syndrome 3. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Autosomal dominant inheritance - Prolonged QT interval - Sudden cardiac death - Syncope - Torsade de pointes - Ventricular fibrillation - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.

What is (are) Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia ?
|
Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare condition in which cells called neuroendocrine cells spread and cluster in the small airways of the lungs. The majority of affected individuals are middled-aged women. Symptoms include shortness of breath and coughing. It is considered to be a precursor for pulmonary carcinoid tumors. Because so few cases have been reported in the medical literature, there is limited information on the prognosis and management of this condition.

What is (are) Spondyloepiphyseal dysplasia congenita ?
|
Spondyloepiphyseal dysplasia congenita is an inherited disorder of bone growth that affects the bones of the spine and ends of the long bones in the arms and legs. Features of this condition include short stature (dwarfism); a very short trunk and neck; abnormal curvature of the spine; barrel-shaped chest; shortened limbs; an abnormality of the hip joint; and problems with vision and hearing. Arthritis and decreased joint mobility often develop early in life. More than 175 cases have been reported in the scientific literature. This condition is caused by mutations in the COL2A1 gene and is inherited in an autosomal dominant pattern. Most cases result from new mutations in the gene and occur in people with no family history of the condition.
