HLA-DQ5 [SEP] found in taxon
HLA-DQ5
HLA-DQ5 (DQ5) is a human leukocyte antigen serotype subgroup within HLA-DQ(DQ) serotypes. The serotype is determined by the antibody recognition of β subset of DQ β-chains. The β-chain of DQ is encoded by HLA-DQB1 locus and DQ5 are encoded by the HLA-DQB1 allele group. This group currently contains 4 common alleles, DQB1, , , and . HLA-DQ5 and HLA-DQB1*05 are almost synonymous in meaning. DQ5 β-chains combine
Rheumatoid arthritis The primary involvement appears to be DR10.
Genetic Linkage.
HLA-DR10 is not genetically linked to DR51, DR52 or DR53, but is linked to HLA-DQ1 and DQ5 serotypes. One haplotype found in caucasians is the HLA-A1-B37-Cw6-DR10-DQ5.
