TTN and left ventricular noncompaction: Likewise, isolated and familial LVNC has been associated with various genes including tafazzin (G4.5) (Bione et al., 1996), Z‐band alternatively spliced PDZ motif‐containing protein (ZASP) (Vatta et al., 2003), transcription factor TBX20 (Kodo et al., 2016), MYH7 (Budde et al., 2007), myosin‐binding protein C (MYBPC3) (van Waning et al., 2018), titin (TTN) (van Waning et al., 2018), alpha‐dystrobrevin (DTNA) (Kenton et al., 2004), and FK‐binding protein‐12(FKBP12) (Kenton et al., 2004).
