IL23R and type 2 diabetes mellitus: Thus, this group found significant associations between three SNP genotypes and type 2 diabetes, IL12B rs6887695-CC (OR = 2.90), IL12B rs3212227-CC (OR = 5.90), and IL23R rs2201841-GG (OR = 2.69), demonstrating this way that the genetic risk of PsD-related diabetes might be governed by genes outside the HLA system [22].
