Overview

These Snx17 and Lrp2 mutations were 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 mutant strain, carrying at least two mutations, 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.

Two mutant phenotypes are observed. In the first (associated with the Snx17 gene, sorting nexin 17), homozygotes demonstrate double outlet right ventricle (DORV)/overriding aorta (Ao), and atrioventricular septal defect (AVSD). Anopthalmia and duplex kidneys are also seen.

In the second phenotype (associated with the Lrp2 gene, low density lipoprotein receptor-related protein 2), persistent truncus arteriosus (PTA), aortic arch anomalies, and vascular ring are seen. Agnathia, microstomia, holoprosencephaly, omphalocele, and low set ears are also seen.

Development

This ENU-induced mutation strain, carrying at least two mutations, was created and maintained on a C57BL/6J genetic background by the NHLBI Cardiovascular Development Consortium (CvDC), Bench to Bassinet Program. In the Snx17^b2b1625.1Clo allele, an A-to-G single point mutation at position 431 of the cDNA (c.A431G, NM_153680) was discovered through whole exome, high throughput sequencing. This mutation is predicted to cause an amino acid substitution at position 4144 of the encoded protein (p.E144G). In the Lrp2^b2b1625.2Clo allele, an A-to-G single point mutation at position -3 of the cDNA (c.8456-3A>G, NM_001081088) was discovered through whole exome, high throughput sequencing. This mutation is a presumed splicing mutation.

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/).

Molecular Note

This ENU-induced mutation was isolated in a screen at the University of Pittsburgh. It is a subline of b2b1625Clo. The molecular lesion is an A to G substituation at coding nucleotide 431 in exon 5 of the cDNA (c.431A>G, NM_153680). This changes the glutamic acid residue to glycine at position 144 of the encoded protein (p.E144G).

Molecular Note

This ENU-induced mutation was isolated in a screen at the University of Pittsburgh. It is a subline of b2b1625Clo. The molecular lesion is an A to G substitution at nucleotide -3 before coding nucleotide 8456 (c.8456-3A>G, NM_001081088) in intron 44. This changes splice acceptor site AAG to TAG (which may have a different efficiency).

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.
