Summative Diagnosis:
Cardiovascular Phenotype: Overriding aorta/Double outlet right ventricle (DORV) with ventricular septal defects (subaortic, perimembranous, and muscular), atrioventricular septal defects (AVSD), and biventricular hypertrophy
Noncardiovascular Phenotype: Abnormal flexure of the hindlimbs, hydrops, midline fusion defect of the sternal vertebra, hypoplastic thymus, short snout, and cleft palate

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/).
