Trismus pseudocamptodactyly syndrome is a rare genetic condition. A defining feature is the inability to open the mouth completely (trismus). Other signs and symptoms include abnormally short tendons and muscles, resulting in contractures, club foot, and other musculoskeletal abnormalities.
It is an autosomal dominant condition caused by a mutation in MYH8. Approximately 60 cases have been reported worldwide.
Treatment is symptomatic in nature.
