<prompt> Limb girdle muscle dystrophies include all of the following groups of disorders except:SarcoglycanopathiesDystroglycanopathiesDysferlinopathiesCalpainopathies  <response>: Ans. b. Dystroglycanopathies Ref: Harrison 19e p462e-6, 462e-6t. 462e-7t. 18e pp 3492,3493, 3494Calpain-J, Sarcoglycans y,a,b and y and dysferlin are all examples of defective geneloeus in Limb girdle dystrophies. Dystrophin is associated with Duchennes and Beckers type of muscular dystrophies and is not associated with Limb girdle dystrophies.The Limb girdle muscular dystrophies LGMD typically manifest with progressive weakness of pelvic and shoulder girdle musculature. Respiratory insufficiency from weakness of diaphragm and cardiomyopathy may occur. However unlike Duchenne dystrophies Dystrophin intellectual function remains intact.- Harrison 18e p3492Progressive Muscular Dystrophies and Defective GeneproteinDuchenne DystrophinQBeckers DystrophinQLimb girdle Myotilin, Laminin Ac, Caveolin-3 Calpain-3, Dysferlin, y,a,B,y sarcoglycans Telethonin, Fukutin related protein, Titin, TRIM 32 geneEmery Dreifuss Emerin, LamininsMyotonic dystrophy DM1 Unstable expansion of a CTG trinucleotide repeat in a serine threonine protein kinase gene named DMPK on chromosome 19q 13.3 DM2 DNA expansion of a CcTG repeat in the ZNF9 gene on chromosome 3q 13.3-q24Fascioscapulohumeral Deletion distal 4qOculopharyngeal Expansion Poly-A RNA binding protein.
