Summative Diagnosis:
Cardiac phenotype: Cardiovascular phenotype: Heterotaxy with complex congenital heart disease such as dextrocardia/levocardia, transposition of the great arteries (TGA), ventricular (VSD) and atrioventricular septal defects (AVSD), dual inferior vena cava (IVC), interrupted aortic arch type B (IAA), dual hepatic vein, and azygous venous connection. Also observed are mutants with situs inversus totalis without congenital heart defects
Noncardiac phenotype: Abnormal thoracic and abdominal organ situs anomalies, such as dextrogastria, inverted liver lobation, left lung isomerism, malaligned sternal vertebra, and apslenia. Also observed were micrognathia and immotile/dyskinetic airway cilia

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/).
