A study of 40 patients of classical or definite rheumatoid arthritis of North India origin diagnosed on ARA criteria revealed a significant increase in the frequency of HLA‐DR4 (70%) as compared to the control population (1 2.5%) giving a relative risk of 16.33. Thus, in the native North Indian population, the genes for susceptibility to RA seem to be in linkage disequilibrium with the same DR determinant as in the white Caucasoid population.
