title: Complete characterization of the DQB1 first exon polymorphism.
abstract: Here we report an additional source of variation resulting from genetic polymorphism in HLA-DQbeta1 genes, namely, allelic diversity in the first exon of the HLA-DQB1 locus, which encodes the leader peptide sequence. Six different variants, including a novel polymorphic site, were detected among the DBQ1 haplotypes.
