This mutation was derived from the parent line b2b1801Clo.

Summative Diagnosis:
Mutant Type 2:
Cardiovascular phenotype: Double outlet right ventricle (DORV)/overriding aorta (Ao), hypoplastic aortic arch, subaortic ventricular septal defect (VSD), and muscular ventricular septal defect (mVSD)

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
0600	Double outlet right ventricle
1200	Coarctation
1300	Ventricular septal defect
1320	Ventricular septal defect, muscular
