Summative Diagnosis:
Cardiovascular phenotype: Dextrocardia and congenital heart disease associated with heterotaxy, including overriding aorta, ventricular septal defects (VSD), and dual inferior vena cava (IVC). Also observed were mutants with situs inversus totalis without congenital heart defects
Noncardiac phenotype: Situs inversus totalis as well as abnormal thoracic and abdominal organ situs anomalies, such as dextrogastria, hypoplastic spleen, malaligned sternal vertebra, inverted liver and lung lobation, and left lung isomerism. Airway cilia were dyskinetic/immotile

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/).
