Detection of cross-reactive anti-DNA antibody idiotypes in the serum of systemic lupus erythematosus patients and of their relatives
Abstract
Two common cross-reacting anti-DNA antibody idiotypes designated 16/6 and 32/15, previously identified in the serum of patients who have systemic lupus erythematosus, were found in 24% and 7%, respectively, of 147 first-degree relatives. These findings imply that high-frequency germ-line genes exist among lupus relatives, as well as patients. These dominant or public anti-DNA antibody idiotypes are not likely to be pathogenic factors, but are probably a genetically associated phenomenon.
