HLA-B42




major histocompatibility complex (human), class I, B42
Alleles	B4201 B4202
Structure (See HLA-B)
Symbol(s)	HLA-B
EBI-HLA	B*4201
EBI-HLA	B*4202
Locus	chr.6 6p21.31

HLA-B42 (B42) is an HLA-B serotype. The serotype identifies the HLA-B*4201 and *4202 gene products.^[1] HLA-B*4201 is common Central Africa. (For terminology help see: HLA-serotype tutorial)
