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.

Marine carbon component of Hlx European diet has declined from the Mesolithic to present, however the haplotype has not undergone equilibration, therefore diet alone cannot explain its resistance to recombination.

Please help improve it to make it understandable to non-experts gla, without removing the technical details. Most important of which is the TNF tumor necrosis factors with 3 loci in the region.
