HNF1A and type 2 diabetes mellitus: Although there was no evidence for HNF1A association with type 2 diabetes susceptibility in the study either at the single variant or at the gene level, there was a marginal aggregate association with type 2 diabetes risk in a multigene test (p = 0.023) which included rare coding alleles in a set of genes implicated in monogenic/syndromic diabetes or related glycemic traits.15
