1. A significant association was detected between the variant genotype of the PTPN22 gene (C1858T, rs2476601) and T1DM in Kuwaiti Arabs. HLA-DQ2 and DQ8 alleles showed a strong association with T1DM. Of T1DM patients having the variant TT-genotype of the PTPN22 gene, 93% had at least one DQ2 allele and 60% had either a DQ2 or a DQ8 allele.
