This strain is one of a set of eight NOD.B10 congenic Idd5 strains (Stock No. 008893, 008894, 004344,012392, 012393, 012394, and 012395 that resulted by crossing segments of C57BL/10SnJ derived chromosome 1 into the NOD/MrkTac background. These strains may be useful to better understand the variation of diabetic resistance conferred by Idd loci; for studying long-range chromosome remodeling and may be useful for identifying diabetes susceptible candidate genes within the Idd5 subloci.

QTL | Idd5.1 | insulin dependent diabetes susceptibility 5.1 |
This NOD congenic strain, commonly referred to as NOD.B10-Idd5R46, line 2193, carries a diabetes resistant C57BL/10SnJ (Stock No. 000666) chromosome 1 segment. The B10 introgressed segment is defined within D1Mit74 (57.6Mb) through AL671560 (SNP marker at approximately 62Mb) and includes the insulin dependent diabetes susceptibility (Idd)5.1; including candidate gene Ctla4.
Diabetes incidence is modest but significant among 7 month old female mice of this strain, which is reported at 62%, compared with more than 80% in NOD controls (Hunter, et al. 2007).
This strain may be useful to understand the epistatic interactions of Idd5.1 alleles with other Idd loci.
This NOD/MrkTac congenic stock contains a genomic segment, D1Mit74 (57.6Mb) through AL671560 (SNP marker at approximately 62Mb), from C57BL/10SnJ (B10) introgressed into chromosome 1. The B10 genomic segment includes Idd5.1. The major candidate gene for Idd5.1 is Ctla4. This strain was produced by mating mice from NOD/MrkTac (NOD) to B10 followed by 15 additional crosses to NOD with selection for chromosome 1, Idd5 markers. Siblings carrying the B10 derived segments denoted by markers D1Mit74 through AL671560 were intercrossed to make homozygous. 5kSNP Chip Data, based on NCBI, build 37, identifies no B10 genetic contamination of other chromosomes. The Type 1 Diabetes Resource received this strain in 2010.

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.
