Summative Diagnosis:
Mutant Type 1:
Cardiovascular phenotype: Dextrocardia/mesocardia and congenital heart disease associated with heterotaxy, such as double outlet right ventricle (DORV), atrioventricular (AVSD) and ventricular septal defects (VSD), right aortic arch (RAA), right atrial isomerism (RAI), and dual inferior vena cava (IVC)
Noncardiovascular phenotype: Abnormal thoracic and abdominal organ situs anomalies, such as dextrogastria, hypoplastic spleen, inverted liver lobation, and malaligned sternal vertebra. Also observed were cystic lungs and immotile/slow/dyskinetic airway cilia
Mutant Type 2:
Biventricular hypertrophy

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/).
