major histocompatibility complex (human), class I, B50 Alleles B*5001, B*5002, Structure (See HLA-B) Symbol(s) HLA-B EBI-HLA B*5001 B*5002 Locus chr.6 6p21.31
HLA-B50 (B50) is an HLA-B serotype. B50 is a split antigen from the B21 broad antigen, the sister serotype B49. The serotype identifies the more common HLA-B*50 gene products. (For terminology help see: HLA-serotype tutorial)
Serotype + B50 and B21 serotype recognition of some more common HLA B*50 allelesderived from IMGT/HLA B*50 B50 B21 Sample allele % % size (N) 5001 85 3 1700
The B*5002 by serotype definition is a B45 serotype.
