Mutations (more than 200) in the MYH7 gene are usually associated with several structural Cardiomyopathies, such as Hypertrophic (HCM; MIM 192600), Restrictive (RCM), Dilated (DCM; MIM 115200), or Left Ventricular Non-Compaction (LVNC; MIM 613426), as well as myosin storage myopathy (MIM 608358) [33,34,35]. This evidence concerns the gene MYH7 and cardiomyopathy, familial restrictive, 1.
