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 A substitution at coding nucleotide position 1134 in exon 7 of the cDNA (c.1134T>A, NM_206958). This changes the cysteine residue to a stop at position 378 of the encoded protein (p.C378*). Additional incidental mutations were detected in sequencing for the causative mutation, Ltbp1b2b1000Clo, and may be present in stocks carrying this mutation.

Summative Diagnosis:
Cardiodvascular defects: Persistent truncus arteriosus (PTA), double outlet right ventricle (DORV), aortic arch anomalies including interrupted aortic arch (IAA) and vascular ring.
Noncardiac defects: Kidney defects - glomerular cysts and tubular dilations.

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/).

1250 Interrupted aortic arch
2720 Right aortic arch
2760 Vascular ring
4508 Polycystic kidney disease
