In conclusion, the rs225017 polymorphism is associated with greater IR in T2DM and it seems to interact with the Thr92Ala polymorphism in the modulation of IR.
The Thr92Ala variant common in Pima Indians, rs225011, and rs225015 were modestly associated with early-onset T2DM (p=0.01-0.04) in the case-control study, but were not associated with obesity in the obesity case-control study, nor associated with T2DM (at any age) or body-mass index (BMI; as a quantitative trait) in the family-based analysis.
An association among the Thr92Ala DIO2 variant and type 2 diabetes</span>, indices of insulin resistance (HOMA-IR), insulin secretion, free thyroid hormones, and thyrotropin (TSH) was found.
