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 b2b2153.1Clo and b2b2153.2Clo, 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 (b2b2153.1Clo) demonstrate cardiac defects including double outlet right ventricle (DORV) with subaortic ventricular septal defect (VSD), and ventricular hypertrophy. Craniofacial defect with micrognathia, cleft palate, and eye defects are also seen. The b2b2153.2Clo mutation is associated with biventricular hypertrophy, a curly tail, low set ears, cleft palate, micrognathia, and eye defects such as microphthalmia, enopthalmia, and anophthalmia.

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/).
