Summative Diagnosis:
Mutant Type 1:
Cardiovascular phenotype: Double outlet right ventricle (DORV) with subaortic ventricular septal defect (VSD), overriding aorta with perimembranous ventricular septal defect (pmVSD), valvular dysplasia (atrioventricular valve and semilunar valve), pulmonary stenosis, and biventricular hypertrophy
Noncardiovascular phenotype: Hydrops, short snout, micrognathia, cleft palate, hydronephrosis, cystic kidneys, unfused sternum, abnormal flexure of the hindlimbs, hypoplastic thymus

Mutant Type 2:
Cardiovascular phenotype: Ventricular hypertrophy
Noncardiovascular phenotype: Craniofacial defects including microphthalmia, cleft palate, and micrognathia

Fyler Codes
The Fyler code developed by The Boston Children's Heart Foundation in Boston Children's Hospital provides a hierarchical clinical diagnosis of congenital cardiovascular defects and other disorders. These codes are used to delineate pathology in the mutant mouse models that parallel human disease and can be cross referenced to the International Pediatric and Congenital Cardiac Code (IPCCC) (http://www.ipccc.net/).
