LONDON -- Rheumatoid arthritis, a disabling, painful disease of the joints, is linked to two genetic
mutations, one involving a process already treated by drugs and a second offering a new target for therapy, researchers said. Having the variant genes, called TRAF1 and C5, on one chromosome made the malady 30 percent likelier, and the risk was doubled when they were on two, according to a study published today in the New England Journal of Medicine.
