Which percentage of diagnosed lupus cases are sle, systemic lupus erythmatosus?

Lupus: Lupus comes in 4 major types: systemic, discoid (skin only), neonatal, and drug-induced. Some people who have an abnormality in their immune system and fail to make a body defense protein called complement are also at risk for developing lupus. It has been estimated that 1.5 million people in the US have one of these lupus forms. Women are 2-3 times more likely to develop this disease than men.
