Summative Diagnosis:
Cardiovascular phenotypes: Persistant truncus arteriosus (PTA), atrial ventricular septal defect (AVSD), common atrium, abnormal pulmonary artery branching, and duplicated inferior vena cava (IVC).

Noncardiovascular phenotype: Preaxial digit duplication, central polydactyly, micrognathia, and eye defects including anophthalmia and micophthalmia.

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/).
