Comparing HT children with T1D patients T allele and T/T genotype at the IL2RA locus (rs7093069) were statistically significant more frequent in patients with diabetes (P = 0.002, OR = 1.92, 95%CI = 1.25–3.02, the power of the test 0.999, estimated effect size w equal to 0.314, with the total sample size n = 558 and P = 0.002, OR = 4,96, 95%CI = 1.64–22.39, the power of the test 1, estimated effect size w equal to 0.449, with the total sample size n = 354, respectively) (Figures 2, 3). Here, IL2RA is linked to diabetes mellitus.
