is a condition characterized by scleroderma with primary biliary cirrhosis. Scleroderma is mainly limited to CREST syndrome, which includes calcinosis cutis (calcium deposits in the skin), Raynaud's phenomenon, esophageal dysfunction (acid reflux and decrease in motility in the esophagus), sclerodactyly, and telangiectasis. Diffuse scleroderma, or scleroderma that affects blood vessels, internal organs, and the skin, has also been reported. Although generally considered an autoimmune disorder, other causes have been suggested, including genetics. Reynolds syndrome may be caused by mutations in the LBR gene and inherited in an autosomal dominant fashion.
