Trismus-Pseudocamptodactyly Syndrome

Trismus-pseudocamptodactyly syndrome (TPS) is a disorder of muscle development and function. It is characterized by short muscles and tendons resulting in limited range of motion of the hands, legs, and mouth. The most serious complications of the condition occur as a result of the limited mobility of the mouth (trismus). TPS is typically reported to be inherited in an autosomal dominant manner and is caused by mutations in the MYH8 gene. Treatment may involve surgical correction and physical therapy.
