We aimed to investigate the genetic association of polymorphisms in genes previously linked with other AIDs, namely BANK1, IL15 and IL2/IL21 region. A total of 76 T1D patients and 162 controls from Southern Tunisia were recruited for a case-control association study investigating the relationship between sixteen SNPs of the BANK1, IL15 and IL2/IL21 gene region and T1D. In the BANK1 gene, G allele and GG genotype of rs3733197 were significantly increased in the group of T1D patients compared to controls. In addition, in the IL15 gene, the minor allele A of rs10519613 polymorphism was significantly higher in patients than in controls. No significant association was found for SNPS in IL2/IL21 gene region. The analysis of the haplotype structure revealed the G-C-A-C-T haplotype of the IL15 gene as associated with a reduction in the risk of developing T1D, while A-T-A-C-T haplotype increased the risk of developing the disease. Furthermore, in the IL2/IL21 region, only one haplotype consisting of eight SNPs was markedly associated with T1D susceptibility. Moreover, G-C combination of the BANK1/IL15 was significantly increased in T1D patients, compared to controls. Our results establish BANK1 and IL15 as new T1D genetic susceptibility factors and replicate the association of the 4q27 region with T1D. Our data agree with the effect previously observed for other autoimmune conditions and delineate a shared underlying mechanism.engType 1 diabetesBANK1Cytokine genesTunisiajournal article10.1016/j.gene.2013.12.008
