In other investigations no correlation was detected [6-8,10,12,13,15,18,20], except for one publication [9], which reported an association between THADA SNP rs7578597 and a 2-h insulin level during an oral glucose tolerance test but no significant association between the THADA SNP and T2D risk, rendering the association disputable. This evidence concerns the gene THADA and type 2 diabetes mellitus.
