However, a similar study from the Polish population by Buraczynska et al. [33], reported on the association of HSP70-2 (+1267 A/G) SNP with DN subjects, in which the authors had shown that the GG genotype and ‘G’ allele were significantly associated with DN (but not in T2DM), with an OR for the G allele of 4.77 (95% CI: 3.81–5.96). This evidence concerns the gene HSPA1A and type 2 diabetes mellitus.
