10. How Common Is It?
Approximately two in every 100,000 individuals have this disorder. Of those individuals, 84% are women. Other autoimmune and connective tissue disorders are more common, but mixed connective tissue disease remains a rare disease worldwide.
Some cases are initially diagnosed as a single connective tissue disorder, such as rheumatoid arthritis, so the diagnosis rate may be slightly higher than represented. Due to the rarity of this disorder, severe cases are especially uncommon.
