Summative Diagnosis:
Cardiovascular Phenotype: Persistent Truncus Arteriosus (PTA) with ambiguos atrial situs, double outlet right ventricle (DORV), right aortic arch (RAA), duplicated inferior vena cava (IVC), atrioventricular septal defect (AVSD)
Noncardiovascular Phenotype: Hypoplastic/abnormal thymus, cleft palate, duplex kidney, kidney agenesis

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/).
