Summative Diagnosis:
Cardiovascular phenotypes: Overriding aorta/Double outlet right ventricle (DORV) with atrioventricular (AVSD) or ventricular septal defects (VSD), right aortic arch, vascular ring.

Noncardiovascular phenotype: Mutants are runted, with hypoplastic thymus, craniofacial defects including microphthalmia, micrognathia, and cleft palate, and kidney defects such as hydronephrosis, duplex kidney, and glomerular cysts.

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/).
