title: HLA-Dw"SHY": a new lymphocyte defined specificity associated with HLA-DRw10.
abstract: HLA-DRw10 is a relatively new class II serologically-defined alloantigen first described in the 8th International Histocompatibility Workshop. To date the HLA-Dw related to the DRw10 specificity has not been detected. We have studied a Jewish family ("SHY") of Yemenite origin, in which the parents are first cousins who share one HLA haplotype: A29,Cw2,B7,BfF,DRw10,GL02. Two of the offspring in this family are homozygous for this haplotype. MLC family study confirmed that each of the two individuals was homozygous for HLA-Dw. No currently defined HLA-Dw specificity could be assigned to "SHY" using a selected panel of Caucasoid and local HTcs. HLA-Dw"SHY" was shown to segregate with DRw10 positive/Dw blank haplotypes in two families and in 64% (7/11) of DRw10 positive unrelated positive/Dw blank haplotypes in two families and in 64% (7/11) of DRw10 positive unrelated individuals. HTC"SHY" thus expresses the first HLA-Dw specificity associated with DRw10.
