Three heterozygous missense mutations, c.151G>A (E51K), c.551G>A (S184N) and c.733G>C (G245R), were identified in patients with tetralogy of Fallot or persistent truncus arteriosus.
The same heterozygous missense mutation (Ser184Asn) was identified in three patients, including one with tetralogy of Fallot and two with atrial septal defects.
