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)

Additional recommended knowledge

Recognize and detect the effects of electrostatic charges on your balance

Safe Weighing Range Ensures Accurate Results

Daily Visual Balance Check

4201	93	2	1015
4202	95		80

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