Duchenne and Becker muscular dystrophies are X-linked conditions caused by mutations in the DMD gene. They primarily affect males and cause progressive muscle weakness.
How Genetic Is Muscular Dystrophy?
Muscular Dystrophy has a strong genetic basis. Research estimates heritability at approximately 100%, meaning genetic factors account for the majority of variation in whether individuals develop this condition.
Key genes associated with Muscular Dystrophy: DMD,DYSF,EMD. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
