Summative Diagnosis:
Cardiovascular defects: Heterotaxy with congenital heart disease such as hypoplastic right ventricle (RV) with small tricuspid valve. Mutants exhibit normal airway cilia motility.

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
0190	Heterotaxy syndrome
1821	Hypoplastic right ventricle (subnormal cavity volume)
3804	Congenital heart disease
