My aunt has Raynaud's syndrome and has been told that she's at higher risk than the general population for getting Scleroderma in the future. Is this true? She's very concerned and I thought I'd get some info for her to give her peace of mind. Aside from Raynaud's, what are the earliest symptoms of Scleroderma? At what point should she go to her physician? Is there a blood test or some sort of "genetic marker" for Scleroderma?
