Detailed Description

This A3641T Megf8 (multiple EGF-like-domains 8) point 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), transposition of great arteries, dextrocardia, and complete atroventricular septal defect (AVSD). Heterotaxia is 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. An A3641T (Ref seq NM_001160400) point mutation in Megf8 cDNA was discovered through whole exome, high throughput sequencing. This is predicted to alter an arginine residue to an isoleucine at position 1214 (N1214I) in the encoded protein.

General Note

Summative Diagnosis:
Cardiovascular defects: Hetertoaxy with complex congenital heart disease such as transposition of the great arteries (TGA;{SDD}) and dextrocardia with double outlet right ventricle (DORV;{ILL}).
Non-cardiac phenotype: Anopthalmia, short snout, micrognathia, Cleft palate

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
0190	Heterotaxy syndrome
0602	DORV, ventricular defect committed to aorta
0700	D-loop transposition of the great arteries
1120	Complete common atrioventricular canal
3804	Congenital heart disease
3950	{S,D,D}
3973	{I,L,L}
4846	Carpenter syndrome

Molecular Note

This ENU-induced mutation was isolated in a screen at the University of Pittsburgh.The causitive molecular lesion for the cardiovascular phenotypes is an A to T substitution at coding nucleotide 3641 in exon 21 of the cDNA (c.3641A>T, NM_001160400). This changes the asparagine residue to isoleucine at position 1214 in the encoded protein (p.N1214I).

Payment Terms and Conditions

Terms are granted by individual review and stated on the customer invoice(s) and account statement. These transactions are payable in U.S. currency within the granted terms. Payment for services, products, shipping containers, and shipping costs that are rendered are expected within the payment terms indicated on the invoice or stated by contract. Invoices and account balances in arrears of stated terms may result in The Jackson Laboratory pursuing collection activities including but not limited to outside agencies and court filings.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
