Summative Diagnosis:
Cardiovascular phenotype: Double outlet right ventricle (DORV), ventricular septal defects (subaortic VSD or AVSD), ventricular non-compaction, dysplastic cushion-like semilunar and atrioventricular valves
Noncardiovascular phenotype: Vascular congestion, hypoplastic thymus, and cystic kidneys

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
0600	Double outlet right ventricle
0606	DORV + AVSD (AV canal)
1100	Atrioventricular canal (endocardial cushion defect)
1300	Ventricular septal defect
1802	Excessive myocardial trabeculation or noncompaction
4508	Polycystic kidney disease
4906	Non-cardiac abnormality
