GLO1 and type 2 diabetes mellitus: Our observation of equal genotype frequencies between individuals with normal glucose metabolism, impaired glucose metabolism and type 2 diabetes [17], and the lack of association between GLO1 SNPs and iAUC of MGO after an OGTT do not support the possibility that impaired detoxification capacity of MGO caused by GLO1 SNPs are an important contributor to the higher MGO peaks observed after an OGTT.
