In humans, DCM‐causing mutations were also identified in a large number of genes including those encoding cytoskeletal proteins such as FLNC, nuclear membrane protein LMNA or involved in sarcomere stability (Titin, TNNT2, MYH7, TPM1) but also RNA‐binding protein RBM20 (McNally & Mestroni, 2017). The gene discussed is TNNT2; the disease is familial dilated cardiomyopathy.
