Summative Diagnosis:
Cardiovascular Phenotype: Dextrocardia and dextroversion and complex congenital heart defects associated with heterotaxy, such as superior-inferior ventricles, anterior positioning of the aorta, double outlet right ventricle (DORV), DORV with anterior positioning of the aorta (DORV, Taussig Bing subtype), and atrioventricular septal defect (AVSD), right aortic arch (RAA), double aortic arch, dual inferior vena cava (IVC), ventricular non-compaction. Also observed are mutants with situs inversus totatlis without congenital heart defects.

Noncardiovascular Phenotype: Abnormal thoracic and abdominal organ situs anomalies, such as left pulmonary isomerism, some mutant fetuses exhibited absent sternal vertebrae or ribs, few with hydronephrosis and cystic kidneys

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/).
