What is Aceruloplasminemia and explain in detail?
Aceruloplasminemia is a rare autosomal recessive disorder in which the liver can not synthesize the protein ceruloplasmin properly, which is needed to transport copper around the blood. Copper deficiency in the brain results in neurological problems that generally appear in adulthood and worsen over time.
.Aceruloplasminemia has been seen worldwide, but its overall prevalence is unknown. Studies in Japan have estimated that approximately 1 in 2 million adults in this population are affected.Aceruloplasminemia belongs to the group of genetic disorders called neurodegeneration with brain iron accumulation (NBIA).

Signs and symptoms
Patients with aceruloplasminemia develop a variety of movement problems. They may experience dystonia of the head and neck, resulting in repetitive movements and contortions. Other involuntary movements may also occur, such as tremors, chorea, blepharospasms, and grimacing. Affected individuals may also experience ataxia, the lack of coordination of muscle movements. Some develop psychiatric problems and midlife dementia. The type of neurological disruption corresponds to associated regions of iron deposition in the brain and liver.In addition to neurological problems, affected individuals may have diabetes mellitus caused by iron damage to cells in the pancreas that make insulin. This impairs blood sugar regulation and leads to the signs and symptoms of diabetes.Iron accumulation in the tissues and organs results in a corresponding iron deficiency in the blood, leading to anemia. Anemia and diabetes usually occur by the time an affected person is in his or her twenties.Affected individuals also experience retinal degeneration caused by excess iron. The changes result in small opaque spots and areas of atrophy around the edges of the retina. These abnormalities usually do not affect vision but can be observed during an eye examination.

Cause
Aceruloplasminemia is caused by a mutation (a five-base pair insertion in exon 7) in the CP gene, which provides instructions for making a protein called ceruloplasmin, a protein involved in iron transport and processing. Ceruloplasmin helps move iron from the organs and tissues of the body and prepares it for incorporation into a molecule called transferrin, which transports it to red blood cells to help carry oxygen. The CP gene mutation results in the production of ceruloplasmin protein that is unstable or nonfunctional by altering the open reading frame such that the amino acid ligands in the essential carboxyl terminal region are eliminated. When ceruloplasmin is unavailable, transport of iron out of the bodys tissues is impaired
