What causes MCTD? The exact cause of Mixed Connective Tissue Disease is still unknown. However, because the immune system in people with MCTD mistakenly battles against healthy cells, it is considered an autoimmune disorder. When it comes to connective tissue disorders like MCTD, the immune system attacks fibers that are responsible for framing and supporting your body. Researchers are still working to identify what specific proteins (in the immune system) are responsible for the symptoms of MCTD. Symptoms of MC...
