Stock number: 018231
Research areas: Cardiovascular Research, Developmental Biology Research, Internal/Organ Research

Description

This mutation was identified in a screen of ENU-induced mutations and may be useful in studies of congenital heart disease and other developmental defects.

The Jackson Laboratory cannot guarantee that cryorecovery of G1 sperm from the Bench to Bassinet (B2B) collection will be successful or that the anticipated phenotype or genotype will be obtained. The cryorecovery fee for this effort will not be refunded or prorated if the recovery is unsuccessful or is in any way unsatisfactory. Genotyping will be the responsibility of the Purchaser.

Detailed description

This mutation was identified in an ENU screen for recessive cardiovascular development phenotypes in Dr. Cecilia Lo's laboratory, NHLBI Cardiovascular Development Consortium (CvDC). It was recovered from G1 sperm and associated with the phenotype described here. Because G1 sperm were cryopreserved, additional incidental mutations are also segregating in this strain.

Homozygotes demonstrate double outlet right ventricle (DORV), atrioventricular septal defect (AVSD), aortic arch anomalies including right aortic arch (RAA) and/or aberrant left subclavian artery, vascular ring, and aortic valve atresia.

Development

This mutation, identified in an ENU screen for recessive cardiovascular development phenotypes, was created and maintained on a C57BL/6J genetic background by the NHLBI Cardiovascular Development Consortium (CvDC), Bench to Bassinet Program.

Allele

Symbol: Prdm1^b2b1765Clo
Name: Bench to Bassinet Program (B2B/CVDC), mutation 1765 Cecilia Lo
MGI accession ID: MGI:5446157
Generation method: Chemically induced (ENU)
Marker symbol: Prdm1
Marker name: PR domain containing 1, with ZNF domain
Chromosome: 10
Strain of origin: C57BL/6J
Molecular note: This ENU-induced mutation was isolated in a screen at the University of Pittsburgh. The molecular lesion is an A to G substitution at coding nucleotide 1625 of the cDNA (c.1625A>G, NM_007548). This changes the aspartic acid residue to glycine at position 542 of the encoded protein (p.D542G).
General note: Summative Diagnosis:
Cardiac phenotype: Double outlet right ventricle (DORV), atrioventricular septal defect (AVSD), aortic arch anomalies including right aortic arch (RAA) and/or aberrant left subclavian artery, vascular ring, and aortic valve atresia

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

1400	Aortic valve abnormality
2720	Right aortic arch
2730	Aberrant left subclavian artery
2760	Vascular ring
