Disease info

CHD Phenotype

  • Atrial septal defect
  • Ventricular septal defect

Extra Cardiac Phenotype

Dysmorphic facies, Pectus excavatum, Scoliosis, digit deformities, hyperflexibility, Failure to thrive, Hypospadias, Hypogonadism, Gastrointestinal dysfunction, Ocular abnormalities, Intrauterine growth restriction

Incomplete penetrance


Variable expressivity


Animal model

Mouse study

MGI: Homozygous knockout mice have cardiac hyperplasia but not CHD. Heterozygous mutation creates gain of function (phosphorilation).
