HLA-DP [SEP] found in taxon
HLA-DP
HLA-DP is a protein/peptide-antigen receptor and graft-versus-host disease antigen that is composed of 2 subunits, DPα and DPβ. DPα and DPβ are encoded by two loci, HLA-DPA1 and HLA-DPB1, that are found in the MHC Class II (or HLA-D) region in the Human Leukocyte Antigen complex on human chromosome 6 (see protein boxes on right for links).
Less is known about HLA-DP relative to HLA-DQ and
-Zweymüller syndrome.
Clinical significance Vasculitis.
A link has been shown between ANCA-associated vasculitis and SNPs in the COL11A2 gene in a Genomewide Association Study. It is proposed that this association may be due to linkage disequilibrium between a SNP in the HLA-DP locus and SNPs in COL11A2. This is theorised as the SNP in the HLA molecule was found to be very strongly associated with these diseases with evidence for a single genetic association.
