[ | [https://www.uniprot.org/uniprot/DMD_HUMAN DMD_HUMAN] Defects in DMD are the cause of Duchenne muscular dystrophy (DMD) [MIM:[https://omim.org/entry/310200 310200]. DMD is the most common form of muscular dystrophy; a sex-linked recessive disorder. It typically presents in boys aged 3 to 7 year as proximal muscle weakness causing waddling gait, toe-walking, lordosis, frequent falls, and difficulty in standing up and climbing up stairs. The pelvic girdle is affected first, then the shoulder girdle. Progression is steady and most patients are confined to a wheelchair by age of 10 or 12. Flexion contractures and scoliosis ultimately occur. About 50% of patients have a lower IQ than their genetic expectations would suggest. There is no treatment.<ref>PMID:8401582</ref> <ref>PMID:7981690</ref> <ref>PMID:8817332</ref> <ref>PMID:9851445</ref> Defects in DMD are the cause of Becker muscular dystrophy (BMD) [MIM:[https://omim.org/entry/300376 300376]. BMD resembles DMD in hereditary and clinical features but is later in onset and more benign.<ref>PMID:10573008</ref> Defects in DMD are a cause of cardiomyopathy dilated X-linked type 3B (CMD3B) [MIM:[https://omim.org/entry/302045 302045]; also known as X-linked dilated cardiomyopathy (XLCM). Dilated cardiomyopathy is a disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death.<ref>PMID:9170407</ref> <ref>PMID:12354438</ref> <ref>PMID:12359139</ref> | ||

[ | [https://www.uniprot.org/uniprot/DMD_HUMAN DMD_HUMAN] Anchors the extracellular matrix to the cytoskeleton via F-actin. Ligand for dystroglycan. Component of the dystrophin-associated glycoprotein complex which accumulates at the neuromuscular junction (NMJ) and at a variety of synapses in the peripheral and central nervous systems and has a structural function in stabilizing the sarcolemma. Also implicated in signaling events and synaptic transmission.<ref>PMID:16710609</ref> | ||
