GAD2 and type 1 diabetes mellitus: When the frequencies of rs763361 TT genotype in T1D patients and controls were stratified for gender, the susceptibility risk was observed for T1D females (P = 0.0012), but not for males (Table 4).Further, when considering the entire population (patients with T1D and controls), those subjects carrying the rs763361 TT genotype had an increased frequency of anti-GAD65 autoantibody: 31.9% × 24.5%; OR = 1.57; CI = 1.136–2.194; and P = 0.0081 (Table 5).
