Trismus-Pseudocamptodactyly Syndrome is a very rare inherited disorder characterized by the inability to completely open the mouth (trismus), causing difficulty with chewing (mastication) and/or the presence of abnormally short muscle-tendon units in the fingers, causing the fingers to curve or bend (camptodactyly) when the hand is bent back at the wrist (dorsiflexion). Because the fingers are not permanently bent or curved, this particular finding is termed "pseudocamptodactyly" (pseudo meaning false). In addition, the muscle-tendon units of the forearms and/or the legs may also be abnormally short, resulting in limited movements and various deformities of the feet. Individuals with this disorder are slightly shorter than would otherwise be expected (mild short stature). The severity of these physical findings varies from individual to individual. Trismus-Pseudocamptodactyly Syndrome is thought to be inherited as an autosomal dominant trait.
