HLA-B73

From Wikipedia, the free encyclopedia
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)

Serotype

[edit]

B*73:01 is one of the four B alleles that reacts with neither Bw4 nor Bw6. The others are B*18:06, B*46:01, and B*55:03.[3]
