Class II HLA antigens in multiple sclerosis.

Abstract
HLA typing in Wellington revealed a strong association of multiple sclerosis with DR2 than with DQw1. The association of DQw1 appeared to be due to linkage disequilibrium of this antigen with DR2. These results, when considered in conjunction with other studies, are most easily explained by the hypothesis that susceptibility to multiple sclerosis is influenced by multiple risk factors, with DR2 being an importnat risk factor in Caucasoid populations.
