A SFC type 1 is a scleroderma-associated autoantibody. This antibody typically causes the body to form sclerotic lesions in connective tissue, leading to organ fibrosis and eventually causing death. The sclera is the thin white layer around your eye that gives it its color, hence the name scleroderma. If you have this type of illness, you may experience symptoms like pain or swelling in joints, Raynaud’s phenomenon (a blood vessel disorder), erythrocyte sedimentation rate elevation (ESR) levels, and decreased lung function due to interstitial lung disease, among others. SFC Type 1 is also known as Anti-centromere Antibody Associated scleroderma. This type of scleroderma is an autoimmune disorder. The body’s immune system attacks itself and causes inflammation in different parts of the body, such as connective tissue and organs.
Sclerosis can also affect the heart valves causing valve damage that could lead to heart failure or sudden death.
