Variants in TTN (n=272, 34%) and MYH7 (n=158, 20%) were most prevalent among DCM G+, followed by SCN5A (n=59, 7%), FLNC (n=56, 7%), DSP (n=49, 6%), DES (n=49, 6%), Lamin A/C (LMNA; n=42, 5%), TNNI3 (n=35, 4%), and TNNT2 (n=32, 4%). This evidence concerns the gene DSP and familial dilated cardiomyopathy.
