title: HLA-linked susceptibility gene of Takayasu Disease.
abstract: The HLA-A, B, DR and MB antigens were investigated in patients suffering from Takayasu disease (Aortitis syndrome). Out of twenty-one HLA-A and B antigens tested, only HLA-Bw52 was significantly deviated (30147, PF = 63.8%, RR = 7.8) from the controls (14/76, PF = 18.4%). Since in the Japanese, HLA-Bw52 is in positive linkage disequilibria with HLA-DR2 and MB1, the association of the DR2 and MB1 antigens with Takayasu disease was studied. The HLA-DR2 antigen was significantly increased (23/30, PF = 76.7%,, RR = 6.0) in patients compared with the control (18/51, PF = 35.3%). Moreover, an almost perfect association of MBI (29/30, PF = 96.7%, RR = 12.6) with Takayasu disease was demonstrated. This finding supports the hypothesis that the genes in the HLA-D region play a major role in determining the susceptibility to Takayasu disease.
