My mum has systemic lupus and I was wondering if this is hereditary? Is there a chance I will get it too (or my daughters)?

You ask, "Is lupus a genetic disease?" The answer for most people is "no". Lupus does not have a strong 'genetic tendency' seen in many other diseases, but there is evidence emerging that a small but definite genetic tendency exists. As lupus becomes more recognised and more readily diagnosed there are clearly more families, in whom a lupus link exists, and it is these families which are providing important data for research.
