Verification of markers at known diabetes susceptibility/resistance (Idd) loci

As an extension of the genome scan, we concentrate on all reported diabetes susceptibility/resistance loci in a separate genomic microsatellite analysis for stocks in which a congenic interval, transgene or gene knockout have been introduced from another strain into NOD (or NOD genome introduced into a diabetes resistant background). The markers used allow allele distinction between most donor and recipient strains. It should be noted that not all Idd susceptibility alleles are NOD in origin (e.g., Idd7 on Chromosome 7 and Idd14 on Chromosome 13).

The following table is a listing of the markers used:

We are always in seach of additional markers polymorphic between NOD, 129, and C57BL/6.  If you know of any we do not currently include, please email the T1DR Project Manager (t1dr-info@jax.org) with this information.
