Identification of a novel HLA-DQB1 allele, DQB1*0314, by sequence-based typing in the Korean population.

摘要

The polymorphism of HLA class II genes is largely confined to the exon 2 region. Sequence analysis of exon 2 of the DQB1 gene revealed the novel polymorphism in the Korean population. The new DQB1 allele, DQB1*0314, was differed from DQB1*0304 only at codon 46 (GAG-->GGG), corresponding to non-synonymous amino acid change (Glu-->Gly).
