Stock number: 013657
Research areas: Cardiovascular Research, Developmental Biology Research, Internal/Organ Research

Description

This strain carries multiple undefined mutations identified in a screen of ENU-induced mutations and may be useful in studies of congenital heart disease.

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 strain, carrying undefined mutations b2b904.1Clo and b2b904.2Clo, 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 of mutant type 1 demonstrate right ventricular myocardial noncompaction and a dilated ventricular chamber. Mutant type 2 animals show ventricular hypertrophy.

Development

This strain contains at least two undefined mutations (b2b904.1Clo and b2b904.2Clo) that were identified in an ENU screen for recessive cardiovascular development phenotypes. It was created and maintained on a C57BL/6J genetic background by the NHLBI Cardiovascular Development Consortium (CvDC), Bench to Bassinet Program.

Allele

Symbol: b2b904Clo
Name: Bench to Bassinet Program (B2B/CVDC), mutation 904 Cecilia Lo
MGI accession ID: MGI:5431494
Generation method: Chemically induced (ENU)
Marker symbol: b2b904Clo
Marker name: Mutant line 904
Chromosome: UN
Strain of origin: C57BL/6J
Molecular note: This ENU-induced mutation was isolated in a screen at the University of Pittsburgh. More than one mutation in this line results in a discernible phenotype in a homozygous recessive screen. At least two segregating phenotype groups are identified. See b2b904.1Clo and b2b904.2Clo
General note: Summative Diagnosis:
Mutant phenotype 1: Right ventricular myocardial noncompaction, dilated ventricular chamber
Mutant phenotype 2: Biventricular hypertrophy

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
1802	Excessive myocardial trabeculation or noncompaction
3608	Left ventricular hypertrophy
3609	Right ventricular hypertrophy
7505	Biventricular hypertrophy
