Scleroderma is a group of rare diseases that involves hardening and thickening of the skin. Internal organs can also be damaged.
Tests and diagnosis
Genetic testing is used to detect altered genes that may cause illness or disease. Although genetic testing can offer important health information, it has limitations.
