-
- Trismus Pseudocamptodactyly Syndrome is a rare disorder inherited as an
- autosomal dominant genetic trait. The major features of this disorder are an
- inability to open the mouth completely and a bending deformity of the fingers
- that occurs when extending the wrist backward. Abnormally short muscle
- tendons are the cause of these conditions.
-
- Symptoms
-
- Pseudocamptodactyly Syndrome is a rare disorder in which the patient is born
- with short muscle tendons that prevent normal growth and development. One of
- the major features of this disorder is a limited ability to open the mouth.
- This condition makes chewing difficult for some. The cause of the limitation
- in opening the mouth has not been determined and in some cases has been so
- subtle that it has gone unnoticed.
-
- Short flexor tendons in the fingers is another feature of Trismus
- Pseudocamptodactyly Syndrome. This causes a condition in which the fingers
- bend toward the palm of the hand when the wrist is flexed backward.
-
- Some patients with Trismus Pseudocamptodactyly Syndrome also have short
- flexor muscles of the feet. This can cause abnormalities such as: toes that
- turn downward (talipes equinovarus); inward curvature of the heel with the
- foot twisted in an abnormal position (metatarsus adductus); a flat arch of
- the foot (pes planus); an abnormality in which the front part of the foot is
- pointed in toward the middle of the body while the heel remains straight
- (metatarsus varus); and/or a condition in which the foot is flexed backward
- and turns outward (calcaneovalgus).
-
- Other symptoms found in some patients with Trismus Pseudocamptodactyly
- Syndrome may be: short stature; a short muscle in the back of the leg
- (gastrocnemius); short muscles in the back of the thigh (hamstrings) causing
- a tilt of the pelvis; and/or mild spasms of the neck causing the head to tilt
- (spasmodic torticollis).
-
- Causes
-
- Trismus Pseudocamptodactyly Syndrome is inherited as an autosomal dominant
- genetic trait with a variance in the severity. Human traits, including the
- classic genetic diseases, are the product of the interaction of two genes,
- one received from the father and one from the mother. In dominant disorders
- a single copy of the disease gene (received from either the mother or father)
- will be expressed "dominating" the other normal gene and resulting in the
- appearance of the disease. The risk of transmitting the disorder from
- affected parent to offspring is fifty percent for each pregnancy regardless
- of the sex of the resulting child.
-
- Affected Population
-
- Trismus Pseudocamptodactyly Syndrome is a rare disorder that affects males
- and females in equal numbers. Many American cases of this disorder have been
- traced to a Dutch girl who migrated to Tennessee. Five cases in three
- generations of a Japanese family have also been reported. There have been
- over thirty-five cases of this disorder reported in the medical literature.
-
- Related Disorders
-
- Symptoms of the following disorders can be similar to those of Trismus
- Pseudocamptodactyly Syndrome. Comparisons may be useful for a differential
- diagnosis:
-
- Camptodactyly is a rare disorder that may occur alone or be associated
- with a syndrome. When Camptodactyly occurs alone it is inherited as an
- autosomal dominant genetic trait. This disorder is characterized by fingers
- flexed towards the palm of the hand. Typically all the fingers are affected
- except the thumb. The toes may be affected in some cases. Camptodactyly
- affects males and females equally.
-
- Gordon Syndrome is a rare disorder that belongs to a group of genetic
- musculoskeletal disorders called the Distal Arthrogryposes. This disorder is
- characterized by permanent flexion of one or more fingers (camptodactyly), a
- cleft palate, and clubfeet. Other developmental abnormalities may also
- occur. (For more information on this disorder, choose "Gordon Syndrome" as
- your search term in the Rare Disease Database).
-
- Spasmodic Torticollis is a tonic or intermittent spasm of the neck
- muscles resulting in rotation and tilting of the head which is often painful.
- There are three different varieties of the disorder: tonic causing sustained
- turning of the head due to increased asymmetric muscle tone in one or more
- neck muscles; clonic which causes shaking movements of the head; and mixed
- tonic and clonic involving both kinds of movement. (For more information on
- this disorder choose "Spasmodic Torticollis as your search term in the Rare
- Disease Database).
-
- Therapies: Standard
-
- Patients with deformities of the foot will require orthopedic care. Physical
- Therapy may be of benefit to some patients.
-
- Genetic counseling may be of benefit for patients and their families.
- Genetic testing of families (linkage analysis) has been performed to identify
- carriers of the gene. Other treatment is symptomatic and supportive.
-
- Therapies: Investigational
-
- Research on birth defects and their causes is ongoing. The National
- Institutes of Health (NIH) is sponsoring the Human Genome Project which is
- aimed at mapping every gene in the human body and learning why they sometimes
- malfunction. It is hoped that this new knowledge will lead to prevention and
- treatment of genetic disorders in the future.
