Mixed connective tissue disease

Summary of Mixed connective tissue disease
Mixed connective tissue disease is an autoimmune disease in which the body's defense system attacks itself. Mixed connective tissue disease combines features of scleroderma, myositis, systemic lupus erythematosus, and rheumatoid arthritis and is thus considered an overlap syndrome. Distinguishing laboratory characteristics are a positive, speckled antinuclear antibody and an anti-U1 ribonucleoprotein antibody.
