“World Lupus Day was 5/10/23 and by WELCOA a health topic for May. Genes do play a role in the predisposition to the development of lupus. There are dozens of known genetic variants linked to lupus. These genes impact both who gets lupus and how severe it is.  20 percent of people with lupus will have a parent or sibling who already has lupus or may develop lupus. About 5 percent of the children born to individuals with lupus will develop the illness.  Although lupus can develop in people with no family history of lupus, there are likely to be other autoimmune diseases in some family members.  Lupus is not contagious, not even through sexual contact. You cannot “catch” lupus from someone or “give” lupus to someone.
