Additionally, compared to Hypertrophic Cardiomyopathy mouse models [52], [53], [54], ErbB2 transgenic mice have a much greater degree of disarray, and thus may be useful in dissecting molecular mechanisms of disarray and the effects of myocardial disarray on cardiomyocyte physiology. This evidence concerns the gene ERBB2 and hypertrophic cardiomyopathy.
