Summative Diagnosis:
Mutant Type 1:
Cardiovascular phenotypes: Dextrocardia and complex congenital heart disease associated with heterotaxy, including transposition of the great arteries (TGA), overriding aorta, atrioventricular (AVSD) and ventricular septal defects (VSD), right atrial isomerism (RAI), coronary fistula, ventricular non-compaction, and inverted hemiazygous connection. Also observed are mutants with situs inversus totalis without congenital heart defects

Noncardiovascular phenotype: Situs inversus totalis as well as abnormal thoracic and abdominal organ situs anomalies, such as dextrogastria, inverted liver and lung lobation, and malaligned sternal vertebra. Airway cilia are immotile


Mutant Type 2:
Cardiovascular phenotypes: Biventricular hypertrophy with perimembranous ventricular septal defect (VSD)

Phenotypic Similarity to Human Syndrome:
Mutant Type 1:
Heterotaxy

Primary Ciliary Dyskinesia (PCD)



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/).
