Summative Diagnosis:
Cardiac Phenotype: Congenital heart disease (CHD) associated with heterotaxy with transposition of the great arteries (TGA), atrioventricular septal defect (AVSD)
Noncardiac phenotype: Left bronchial isomerism, hypoplastic spleen

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 Code ID	Code Description
0190	Heterotaxy syndrome
0720	D-loop TGA with ventricular septal defect
1100	Atrioventricular canal (endocardial cushion defect)
2050	Atrial septal defect
3804	Congenital heart disease
4239	Left bronchial isomerism
