Furthermore, the absence of Cerl2 in Cerl2 KO embryos leads to a range of laterality defects and/or cardiovascular malformations such as incomplete atrial and ventricular septation, TGA, DORV, randomized positioning of the cardiac apex, ventricular hypertrophy and/or heterotaxy of the abdominal organs, and a significant mortality rate within a few hours after birth is observed [30, 31]. The gene discussed is DAND5; the disease is Ventricular hypertrophy.
