major histocompatibility complex (human), class I, B42
Alleles B*4201
B*4202

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 in Central Africa. (For terminology help see: HLA-serotype tutorial)

Serological typing for B*4201 and B*4202 is relatively efficient.
