HLA-B73

major histocompatibility complex (human), class I, B73
Alleles	B*7301
Structure (See HLA-B)
Symbol(s)	HLA-B
EBI-HLA	B*7301
Locus	chr.6 6p21.31

HLA-B73 (B73) is an HLA-B serotype. The serotype identifies the HLA-B*7301 gene product.^[1] Part of B*7301 is similar to the HLA-B22 family, however part resembles the domains seen in other apes.^[2] B73 is more common in Western Indian Ocean, Mediterranean and Africa. (For terminology help see: HLA-serotype tutorial)
