Summative Diagnosis:
Cardiovascular Phenotype: Persistent truncus arteriosus (PTA, Typa 1 and Type A4), atrioventricular septal defect (AVSD), muscular ventricular septal defect (VSD), ventricular non-compaction, absent semilunar valves
Noncardiovascular Phenotype: Hydronephrosis

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
0500	Truncus arteriosus
1100	Atrioventricular canal (endocardial cushion defect)
1802	Excessive myocardial trabeculation or noncompaction
4502	Hydronephrosis
4906	Non-cardiac abnormality
