Wang et al. analyzed 105 HCM patients who underwent genetic testing for eight HCM-associated sarcomere genes (myosin-binding protein C (MYBPC3), β-myosin heavy chain (MYH7), essential and regulatory myosin light chains, cardiac troponin T, cardiac troponin I, α-tropomyosin, and cardiac actin) and three HCM phenocopy genes (LAMP2 for Danon disease, GLA for Fabry disease, and PRKAG2 for PRKAG2 cardiomyopathy) along with CMR. This evidence concerns the gene MYBPC3 and cardiomyopathy.
