MYH6 (Myosin-6) variants and mutations

MYH6 (also known as Myosin-6) is a human protein-coding gene encoding a myosin-6 protein. Its alpha-myosin motor contributes to ATP-dependent force generation in the cardiac sarcomere, particularly in atrial myocardium. Pathogenic variants can cause cardiomyopathy, congenital heart defects, and selected conduction-system disorders. This analysis covers 2,707 MYH6 variants and mutations. Of these, 67% have computational variant effect predictions. Disease context includes hypertrophic cardiomyopathy, dilated cardiomyopathy 1EE, and atrial septal defect 3. Example MYH6 variants include D3G, D3N, and A4T.
