A complex of HLA-D specificities detected by HTC typing: Dw7, Dw11, and TMo.

Homozygous typing cells defining HLA-D antigens related to Dw7 appear to identify a complex of partially overlapping structures. The relationships between these specificities were analyzed using 7th Workshop cells and other cells sent to the reference laboratory. The local cells JLe and KA seem to fit the antigen Dw11, which is in large part included in Dw7. TMo defines a component that is rare in normal whites and frequently observed in children with rheumatoid arthritis.
