Gene Linked to Lupus Might Explain Gender Difference in Disease Risk

In an international human genetic study, researchers at UT Southwestern Medical Center have identified a gene linked to the autoimmune disease lupus, and its location on the X chromosome might help explain why females are 10 times more susceptible to the disease than males.

Identifying this gene, IRAK1, as a disease gene may also have therapeutic implications, said Dr. Chandra Mohan, professor of internal medicine and senior author of the study. "Our work also shows that blocking IRAK1 action shuts down lupus in an animal model. Though many genes may be involved in lupus, we only have very limited information on them," he said.

The study appears online this week in the Proceedings of the National Academy of Sciences.
