Mutation origin

• Strain of Origin: C57BL/6J
• Project Collection: B2B/CvDC

Mutation description

• Allele Type: Chemically induced (ENU)
• Mutation: Single point mutation
• Mutation details: This 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 6612 in exon 39 of the cDNA (c.6612T>A, NM_001033385). This changes the tyrosine residue to a translation stop at position 2204 of the encoded protein (p.Y2204*). (J:175213) Additional incidental mutations were detected in sequencing for the causative mutation, Lrp2^b2b2671Clo, and may be present in stocks carrying this mutation.

Notes

Summative Diagnosis:
Cardiovascular Phenotype: Persistent truncus arteriosis (PTA, Type A1, A2, A4), permembranous ventricular septal defects (pmVSD) and muscular ventricular septal defect (mVSD), right aortic arch (RAA), ventricular non-compaction, ventricular hypertrophy
Noncardiovascular Phenotype: Short snout, anophthalmia/microphthalmia, short snount/micrognathia, hypoplastic thymus, incomplete closure of the umbilical herniation, cystic kidneys, hydrnephrosis, hooked tail

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/).
