NFKB1 and type 2 diabetes mellitus: To our knowledge, this SNP has not been previously investigated in other diseases, although it was in high LD with the common rs28362491 (−94 ATTG indel) in the NFKB1 promoter that was associated with differences in gene expression (the deletion would drive less promoter activity) and has been widely studied in cancer and immune-mediated processes [19, 20, 28], including the risk for type 2 diabetes in our population [29].
