The single DR beta gene of the DRw8 haplotype is closely related to the DR beta 3III gene encoding DRw52. Academic Article uri icon

abstract

  • In most individuals two HLA-DR beta genes are expressed from each chromosome. One of these genes encodes one of the classical DR specificities, while the other encodes either of the supertypic DRw52/DRw53 specificities. In addition to these genes usually one or two DR beta pseudogenes are present. In contrast, the DRw8 chromosomal region only contains a single DR beta gene. To determine the relationship of this single gene to the multiple DR beta genes of other DR specificities, comparisons of Southern genomic blots were carried out. In this analysis genomic clones for each individual DR beta chain locus were included. The DR beta w8 gene was indistinguishable from the DR beta III gene of DR3 cells (encoding DRw52), suggesting that it is closely related to the latter gene. The functional implications of this finding are discussed.
