Summative Diagnosis:
Cardiovascular defect: Double outlet right ventricle (DORV), overriding aorta, perimembranous and muscular ventricular septal defects (VSD), and one mutant with hypoplastic transverse arch.
Non-cardiovascular phenotype: Cystic lungs.

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/).

Fyler Code ID	Code Description
1220	Tubular hypoplasia of aorta + coarctation
1310	Ventricular septal defect, membranous
1320	Ventricular septal defect, muscular
1340	Ventricular septal defect, ECD type
3810	Heart disease
4200	Respiratory anomaly
