The HLA-DQ8 haplotype (p < 0.0001) and DQ2/8 genotype (p < 0.02) predominated among Swedish compared with non-Swedish patients.

METHODS: Blood samples from 243 paediatric patients were genotyped for the high-risk HLA haplotypes DR3-DQ2 (DQA1*05-DQB1*02) and DR4-DQ8 (DRB1*0401/2/4/5-DQB1*0302) and PTPN22 C1858 T polymorphism.

The frequency of the risk haplotype DR4-DQ8 was higher in Swedish than in Lithuanian patients (p = 0.004), as well as the high-risk combination of DR4-DQ8 and DR3-DQ2 haplotypes (p = 0.009).

IAA, IA2 autoantibodies, and ICA are increased in DQ8 positives; GAD65 antibodies are increased in DQ2 positives.
