Finally a meta-analysis of 24,198 individuals demonstrated FTO rs9939609 (in high LD with rs8050136 with r2 > 0.8) was highly significantly associated with T2D before and after adjustment for BMI (before adjustment OR = 1.14, 95% CI = 1.12–1.16, p = 1.00 × 10−41; after adjustment OR = 1.07, 95% CI = 1.05–1.09, p = 6.42 × 10−41) (Xi et al., 2014). Here, FTO is linked to type 2 diabetes mellitus.
