Strain of Origin:  C57BL/6J
Project Collection: B2B/CvDC
Allele Type:    Chemically induced (ENU)
Mutation:    Single point mutation
Mutation detailsThis ENU-induced mutation was isolated in a screen at the University of Pittsburgh. The molecular lesion is a T to C substitution at coding nucleotide 1645 in exon 19 of the cDNA (c.1645T>C, NM_026319). This changes the tryptophan residue to arginine at position 549 of the encoded protein (p.W549R). (J:175213) Additional incidental mutations were detected in sequencing for the causative mutation, Ift74b2b796Clo, and may be present in stocks carrying this mutation.

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
0606 DORV + AVSD (AV canal)
1100 Atrioventricular canal (endocardial cushion defect)
1140 Common atrium
2810 Inferior vena cava anomaly
3804 Congenital heart disease
4235 Pulmonary malformation
