Exome sequencing analysis between SM/J and A/J mice identified 4 genes (Itga6, Zak, Gpr155, and Mtx2) with nonsynonymous coding SNPs. These four genes might be candidate genes for type 2 diabetes caused by gene-gene interactions.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
