Summative Diagnosis:
Mutant Type 1: Cardiac defects: Congenital heart disease associated with heterotaxy such as double outlet right ventricle (DORV) with interrupted aortic arch, atrioventricular septal defect (AVSD), and hypoplastic right ventricle (RV)
Noncardiac defects: Highly cystic kidneys with tubule cysts
Mutant Type 2: Cardiac defects: Ventricular hypertrophy

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/).
