Data suggest IGT10 mice, diabetes type 2 model, exhibit 2 genetic defects: haploinsufficiency (heterozygosity for null allele) of insulin receptor (Insr); splice-site mutation in protein phosphatase 2 regulatory subunit B alpha (Ppp2r2a). Inheritance of either allele results in insulin resistance but not overt diabetes. Double heterozygosity leads to insulin resistance and diabetes type 2 without increase in body weight.

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.
