Summative Diagnosis:
Laterality defect phenotypes: Heterotaxy and situs inversus totalis with left pulmonary isomerism, hypoplastic spleen/asplenia, abnormal bilateral inferior vena cava (IVC)
Noncardiac phenotype: Malaligned sternovertebrae, dyskinetic/immotile respiratory 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/).

Fyler Codes	Code Description
191	Heterotaxy Syndrome
