The gene that codes for α-dystrobrevin is called DTNA. Mutations in DTNA are known to cause the left ventricular non-compaction type 1 (LVNC1) disease, which is defined by the presence of poor systolic function, and is sometimes associated with other cardiac abnormalities including atrial or ventricular septal defects [108]. The gene discussed is DTNA; the disease is ventricular septal defect.
