International Textbook of Diabetes Mellitus, 4th Ed., Excerpt #165: Molecular Genetics of Type 1 Diabetes Part 2

HLA-DR and -DQ: The highest risk of T1DM is conferred by heterozygosity for the DRB1*0301-DQA1*0501-DQB1*0201 and DRB1*04-DQA1* 0301-DQB1*0302 haplotypes, referred to as the DR3.DQ2/DR4.DQ8 genotype. This allelic combination is carried by 30–40% of individuals with T1DM, but only around 2.5% of the general population [3]. A recent meta-analysis of multiple ethnic groups suggested that this translates into an OR value greater than 16, an unusually large odds ratio for a complex disease [14]. This is consistent with an earlier study which estimated that the risk of developing T1DM was between 1 in 15 and 1 in 25 among those with the DR3.DQ2/DR4.DQ8 genotype, compared with 1 in 300 in the general population [15]. High risk is also conferred by the DR3.DQ2/DR3.DQ2 and DR4.DQ8/DR4.DQ8 homozygous genotypes (OR = 6.32 and OR = 5.68, respectively, from meta-analysis).
