Twelve studies that provided data on the sex distribution of LMNA variants in DCM patients and 6 similar studies on Myosin binding protein 3 (MYBPC3) variants found that 98 out of 152 patients with LMNA variants (69%) and 60 out of 76 patients with MYBPC3 variants (79%) were male (82). This evidence concerns the gene MYBPC3 and familial dilated cardiomyopathy.
