A genetic variant in LINGO2 contributes to the risk of gestational diabetes mellitus in a Chinese population

AbstractGenome ‐wide association studies (GWASs) showed that three single nucleotide polymorphisms (SNPs; rs10968576, rs1412239, and rs824248) in the leucine‐rich repeat and Ig domain containing 2 (LINGO2) were associated with obesity or type 2 diabetes (T2D). We aimed to determine the influence of the LINGO2 variants on the gestational diabetes mellitus (GDM) risk. Thus, we performed a case–control study including 964 GDM cases and 1,021 controls to test the associations between the three LINGO2 variants (rs10968576, rs1412239, and rs824248) and susceptibility to GDM. Logistic regression analyses show ed no significant association between LINGO2 variations (rs10968576 and rs1412239) and GDM susceptibility, but we observed that LINGO2 rs824248 A >  T was significantly associated with an increased risk of GDM using the dominant model (TT/AT vs. AA: adjusted odds ratio [OR] = 1.26, 95% confidence interval [CI] = 1.05–1.51;p = 0.012) and the additive model (TT vs. AT vs. AA: adjusted OR = 1.16, 95% CI = 1.03–1.31;p = 0.016). In the additive model, a stronger risk effect of rs824248 was observed among obese women (prepregnancy body mass index [BMI] >  22 kg/m2, adjusted OR  = 1.34, 95% CI = 1.12–1.59) compared with that in lean women (prepregnancy BMI ≤ 22 kg/m2, adjusted OR  = 1.02, 95% CI  = 0.86–1.21;p = 0.029 for heterogeneity test). Further interactive analyses also detected a significant multi...
