-
- Acrodysostosis is a very rare genetic disorder. Major symptoms may
- include extremely shortened hands and feet, a flattened nose, short stature
- and mental retardation.
-
- Symptoms
-
- Acrodysostosis is characterized by hands and feet that are short with stubby
- fingers and toes, and broad short nails. Short at birth, growth retardation
- continues over the years. The patients exhibit faces with flattened nose
- bridges and a short, wide, "pug" appearance. Underdeveloped jaws, improper
- alignment of teeth, widely spaced eyes and mental retardation also occur.
- Deformity of bones in the arms, legs and elbows occurs as well as early
- fusion of these bones. The head is abnormally short and broad.
-
- Causes
-
- The exact cause of Acrodysostosis is not known, although it has been found
- that the parents of these patients are usually older than normal. The
- disorder is thought to be inherited as an autosomal dominant trait. (Human
- traits, including the classic genetic diseases are the product of the
- interaction of two genes for that condition, 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 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
-
- Acrodysostosis is a very rare disorder and affects females twice as often as
- males.
-
- Related Disorders
-
- Symptoms of the following disorders can be similar to those of
- Acrodysostosis. Comparisons may be useful for a differential diagnosis:
-
- McCune-Albright Syndrome manifests symptoms of early sexual development,
- disabling bone-related pain, and spots of discolored skin. The change in
- bone integrity produces pain and increasing deformity. Additional symptoms
- associated with the disorder may include an increased functioning of the
- thyroid gland, and an enlargement of the extremities of the skeleton.
- Although people with this disorder are exceptionally tall during childhood,
- they stop growing prematurely and are unusually short stature in adulthood.
- (For more information on this disorder, choose "McCune-Albright" as your
- search term in the Rare Disease Database).
-
- Turner Syndrome is a genetic disorder affecting females which is
- characterized by lack of sexual development, small stature, a webbed neck,
- heart defects, and various other congenital abnormalities. Growth is slowed
- and the individual remains unusually short, often under four feet tall at
- adulthood. The jaw may have an unusual shape, and the palate may be arched.
- Intelligence is only rarely impaired. (For more information on this
- disorder, choose "Turner" as your search term in the Rare Disease Database).
-
- Therapies: Standard
-
- Treatment of Acrodysostosis may include plastic surgery in severe cases.
- Genetic counseling may be of benefit for patients and their families. Other
- treatment is symptomatic and supportive.
-
- Therapies: Investigational
