We identified several genes associated with trabeculation that also have evidence for what is termed as left ventricular noncompaction cardiomyopathy (MYH7, MIB1 (GATA6), DES, MYBPC3, TTN, ACTN2, LMNA, PLN, TBX20, TBX5, DTNA and TNNT2)3,53,54. This evidence concerns the gene TBX20 and Left ventricular noncompaction cardiomyopathy.
