Specifically, Barp et al. [16] studied genetic modifiers for dilated cardiomyopathy in a sample of 178 Italians with DMD and found that patients with the LTBP4 rs10880 CC/CT genotype had a higher risk of dilated cardiomyopathy compared with the TT genotype (p < 0.027). Here, LTBP4 is linked to Duchenne muscular dystrophy.
