MYH7 and hypertrophic cardiomyopathy: Both the AID-TAT peptide and the AID-TAT variants were able to prevent the development of hypertrophy in cTnI-G203S and αMHC403/+ (mouse carrying in MYH7 hypertrophic cardiomyopathy mutation in MHY6) mice, as evidenced by improvements in contractility on echocardiography and decreased heart weight–tibial length ratios [89,95].
