This mutation was derived from the parent line b2b1200Clo.

Summative Diagnosis:
Mutant Type 1:
Cardiovascular defects: Heterotaxy with congenital heart disease such as dextroversion with hypoplastic right ventricle (RV), double outlet right ventricle (DORV), muscular and membranous ventricular septal defects, aortic arch anomalies including vascular ring
Non-cardiovascular defects: Duplex kidneys with cysts and hydronephrosis

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/).
