Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the DMD gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

Function
FUNCTION: 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. {ECO:0000250|UniProtKB:P11531, ECO:0000269|PubMed:16710609}.;
Disease
DISEASE: Duchenne muscular dystrophy (DMD) [MIM:310200]: 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. {ECO:0000269|PubMed:12632325, ECO:0000269|PubMed:24302611, ECO:0000269|PubMed:7981690, ECO:0000269|PubMed:8401582, ECO:0000269|PubMed:8817332, ECO:0000269|PubMed:9851445}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Becker muscular dystrophy (BMD) [MIM:300376]: A neuromuscular disorder characterized by dystrophin deficiency. It appears between the age of 5 and 15 years with a proximal motor deficiency of variable progression. Heart involvement can be the initial sign. Becker muscular dystrophy has a more benign course than Duchenne muscular dystrophy. {ECO:0000269|PubMed:10573008}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Cardiomyopathy, dilated, X-linked 3B (CMD3B) [MIM:302045]: A disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death. {ECO:0000269|PubMed:12359139, ECO:0000269|PubMed:25340340, ECO:0000269|PubMed:9170407}. Note=The disease is caused by mutations affecting the gene represented in this entry.;
