What Is Mixed Connective Tissue Disease (MCTD)?

Mixed Connective Tissue Disease (MCTD) is a rare autoimmune disorder that combines features of several connective tissue diseases, including systemic lupus erythematosus (SLE), scleroderma, and polymyositis. This complex condition primarily affects the body’s connective tissues, which play a crucial role in supporting and structuring organs and tissues throughout the body.

MCTD is characterized by the presence of specific autoantibodies, particularly the anti-U1 ribonucleoprotein (RNP) antibody. This antibody is a hallmark of the disease and helps in distinguishing MCTD from other autoimmune disorders. The exact cause of MCTD remains unclear, but it is believed to involve a combination of genetic predisposition and environmental triggers.

Understanding the Autoimmune Aspect
