NCIt synonyms : HLASB; HLADP; DASS-32K24.2; HLA DP1A; Major Histocompatibility Complex, Class II, DP Alpha 1 wt Allele;
NCIt definition : Human HLA-DPA1 wild-type allele is located in the vicinity of 6p21.3 and is approximately
16 kb in length. This allele, which encodes HLA class II histocompatibility antigen,
DP alpha chain protein, is involved in the modulation of antigen presentation and
T-cell mediated immunity. The gene is polymorphic and typing is often performed to
determine histocompatibility for hematopoietic stem cell transplantation.;
NCIt note : The HLA-DPA1 gene is expressed as multiple isoforms that dimerize with HLA-DP beta
chain proteins to form the HLA-DP complex.;
