2001). Notably, we found two cases with several types of cardiac diseases in their families (Postma et al. 2011; Ronvelia et al. 2012). In a family with the TAZ/p.G195* variant, LVNC co‐existed with Barth syndrome, DCM, atrial septal defect, and elevated urine 3‐methylglutaconic acid (3‐MGA) levels (Ronvelia et al. 2012). Lastly, LVNC co‐existed with cardiovascular malformation and Ebstein ̓s anomaly in a family with the MYH7/p.Y283D variant (Postma et al. 2011). This evidence concerns the gene TAFAZZIN and heart disorder.
