Analysis of the expression characteristics of TRIM44 in samples from hypertrophic cardiomyopathy (HCM) patients and healthy heart donors revealed that the expression of TRIM44 in heart tissues was increased significantly under HCM (Fig. 1A,B; n=3 in normal group, n=6 in HCM patient group, P<0.01, HCM group versus normal group). Here, TRIM44 is linked to hypertrophic cardiomyopathy.
