Strain of Origin:  C57BL/6J
Project Collection: B2B/CvDC
Allele Type:    Chemically induced (ENU)
Mutation:    Undefined
Mutation detailsThis ENU-induced mutation was isolated in a screen at the University of Pittsburgh. The molecular lesion is a T to A substitution at coding nucleotide 2755 in exon 20 of the cDNA (c.2755T>A, NM_009390). This changes the tryptophan residue to arginine at position 919 of the encoded protein (p.W919R). (J:175213) Additional incidental mutations were detected in sequencing for the causative mutation, Tll1b2b2476Clo, and may be present in stocks carrying this mutation.

Summative Diagnosis:
Cardiovascular Phenotype: Overriding aorta/double outlet right ventricle (DORV), muscular ventricular septal defect (VSD), ventricular non-compaction, aortic arch anomalies with incomplete vascular ring.
Noncardiovascular phenotype: growth retarded, abnormal palate, hypoplastic thymus

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
0600 Double outlet right ventricle
1300 Ventricular septal defect
1310 Ventricular septal defect, membranous
1320 Ventricular septal defect, muscular
1432 Overriding aortic valve
1802 Excessive myocardial trabeculation or noncompaction
4906 Non-cardiac abnormality
