This undefined 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.

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 laterality defect including situs inversus totalis, double outlet right ventricle (DORV), atrioventricular septal defect (AVSD), pulmonary atresia, and dual inferior vena cava (IVC). Pulmonary agenesis, and immotile/dyskinetic airway cilia motility are also seen.
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.
