HNF1A and Stroke: In the recessive inheritance model, a strong association was observed between the HNF1α (GG + GT) genotypes and the TT genotype with susceptibility to stroke, yielding an OR of 22.14 (95% CI = 1.261 to 388.66), RR of 10.18 (95% CI = 0.686 to 150.96), and a p-value less than 0.034 (Table 6).
