The IL2RA gene has also been associated with type 1 diabetes (T1D) [12]–[14] and localized the association region in two independent groups of SNPs, spanning overlapping regions of 14 and 40 Kb encompassing IL2RA intron 1 and the 5′ regions of IL2RA and the RNA binding motif protein 17 (RBM17) genes. This evidence concerns the gene IL2RA and type 1 diabetes mellitus.
