N2 - In view of our recent report that T cell receptor (TCR) a chain restriction fragment length polymorphism (RFLP) Is associated with multiple sclerosis (MS), we have assessed the possibility that HLA-DR2, HLA-DPw4, and TCR a chain RFLPs may interact to increase the risk of developing MS. Detection of TCR a chain polymorphisms, and HLA-DR and -DP typing were carried out by RFLP analysis on MS patients and healthy controls from the Melbourne metropolitan area. Interaction effects among these loci In producing susceptibility to MS were assessed by hierarchical log-linear analysis. Although HLA-DR2 was significantly associated with MS (x2 = 9.30, P = 0.002), no interactive effect between MS and HLA-DPw4 was observed. Significant interactions were observed with MS and both CQ and Va, with the strongest effect seen with C„ (\2 = 21.30, P < 0.001). The combination of DR2/Ca imparted a relative risk of 47. However, when the data were analysed for four and three way interactions, no significant effects were seen with MS, DR2, DPw4, V„, and Ca, implying that the combined presence of these polymorphic markers is not essential for Increasing susceptibility to MS.
