The new allelic variant HLA-B*38:55Q differs from the closest related B*38:01:01 by one nucleotide substitution at position 373 in exon 3 (TGC>CGC). This results in a difference of one amino acid at residue 101 of the HLA-B heavy chain, from a neutral-polar Cys to a basic-polar Arg, thus impairing disulphide bridge formation in the alpha-2 domain. This alteration of the secondary structure probably affects the maturation of the heavy chain and the level of surface expression, making the HLA-B*38:55Q undetectable by standard serological typing.

Abstract

The new allelic variant HLA-B*38:55Q differs from the closest related B*38:01:01 by one nucleotide substitution at position 373 in exon 3 (TGC>CGC). This results in a difference of one amino acid at residue 101 of the HLA-B heavy chain, from a neutral-polar Cys to a basic-polar Arg, thus impairing disulphide bridge formation in the alpha-2 domain. This alteration of the secondary structure probably affects the maturation of the heavy chain and the level of surface expression, making the HLA-B*38:55Q undetectable by standard serological typing.
