More than 200 mutations in the beta-myosin gene (MYH7) that cause clinically distinct cardiac and/or skeletal myopathies have been reported, but to date, no comprehensive statistical analysis of these mutations has been performed. As a part of this review, we developed a new interactive database and research tool called MyoMAPR (Myopathic Mutation Analysis Profiler and Repository). We report that the distribution of mutations along the beta-myosin gene is not homogeneous, and that myosin is a highly constrained molecule with an uncommon sensitivity to amino acid substitutions. Increasing knowledge of the characteristics of MH7 mutations may provide a valuable resource for scientists and clinicians studying diagnosis, risk stratification, and treatment of disease associated with these mutations.
