Description

This undefined mutation was 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 undefined 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 cardiovascular defects that involve a double outlet right ventricle (DORV), ventricular septal defects (subaortic VSD or AVSD), ventricular non-compaction, dysplastic cushion-like semilunar and atrioventricular valves. Vascular congestion, hypoplastic thymus, and cystic kidneys are also seen.

Development

This undefined 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.

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
0600	Double outlet right ventricle
0606	DORV + AVSD (AV canal)
1100	Atrioventricular canal (endocardial cushion defect)
1300	Ventricular septal defect
1802	Excessive myocardial trabeculation or noncompaction
4508	Polycystic kidney disease
