We observed a significant association between HNF1A variants and type 2 diabetes in the population of European ancestry (OR 1.46 [95% CI 1.00, 2.13], p=0.049), but not in those of African ancestry (OR 1.10 [95% CI 0.77, 1.58], p=0.60) or Hispanic-Latino ancestry (OR 1.00 [95% CI 0.60, 1.64], p=1.0) (Fig. 2, ESM Table 2). Here, HNF1A is linked to type 2 diabetes mellitus.
