pubmed-article:10703621 | pubmed:abstractText | Four new DR52-associated DRB1 alleles are described. One allele, DRB1*1130, is a hybrid between a DRB3*02 allele and a DRB1*11011 allele. The other alleles, DRB1*13072, DRB1*1315, and DRB1*1331, are simple reshufflings of known polymorphic motifs. | lld:pubmed |
