Summative Diagnosis:

Mutant Type 2:
Cardiovascular Phenotype: Persistent truncus arteriosus (PTA, Type 1), atrioventricular ventricular septal defect (AVSD), right aortic arch (RAA), and aberrant left subclavian artery forming vascular ring
Noncardiovascular Phenotype: growth retardation, microphthalmia, syndactyly, micrognathia, cleft palate, hypoplastic kidneys, lungs, and thymus

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
