En los loci HLA-A y -B se observó deficiencia en la frecuencia de heterocigóticos esperada (phaplotipos más. HLA-DQ2 (DQ2) is a serotype group within HLA-DQ (DQ) serotyping system. The serotype is determined by the antibody recognition of β2 subset of DQ β-chains. HLA A1-B8-DR3-DQ2 haplotype is a multigene haplotype that covers a majority of the human major histocompatibility complex on chromosome 6 (not to be.

Juvenile diabetes T1D has a high association with DQ2. One possibility is that peoples from central Asia or the Middle East migrated into Iberia as peoples from Africa crossed into Iberia from the south prior to the Neolithic, recombination occurred resulting in the haplotype, and bearers favorably expanded into Europe prior to the Holocene.
