Summative Diagnosis:
Mutant Type 1: Cardiac phenotype: Persistant truncus arteriosus (PTA) with right aortic arch
Mutant Type 2: Non-cardiac phenotype: Cystic kidney and 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
2720	Right aortic arch
0500	Truncus arteriosus
4502	Hydronephrosis
4508	Polycystic kidney disease
