HLA-B53




major histocompatibility complex (human), class I, B53
Alleles	B5301 B5302
Structure (See HLA-B)
Symbol(s)	HLA-B
EBI-HLA	B*5301
EBI-HLA	B*5302
Locus	chr.6 6p21.31

HLA-B53 (B53) is an HLA-B serotype. The serotype identifies the more common HLA-B*53 gene products. The B53 sequence is identical to B35 but short sequence specifies a Bw4 rather than a Bw6 motif (as found in B35), indicating B53 is a recent product of gene conversion. This suggests an origin for HLA-B53 involving a gene conversion of HLA-B35 by an allele containing this Bw4 sequence. (For terminology help see: HLA-serotype tutorial)
