-
- Wyburn-Mason Syndrome is a rare genetic disorder that usually affects the
- brain, eyes and skin. Major symptoms may include discolored patches on the
- skin, and ballooned areas in the arteries (aneurysms) of the brain and eyes.
-
- Symptoms
-
- Wyburn-Mason Syndrome is usually present at birth but does not become
- apparent until one reaches the thirties. The onset can be either sudden or
- gradual. Usually vision is lost in one eye. This may be accompanied by
- severe headache, vomiting, and the sudden bulging of the affected eye. If an
- aneurysm occurs in the midbrain it may result in a stiff neck, symptoms of
- meningitis, loss of consciousness, ringing in the ears (tinnitus), deafness,
- loss of speech (aphasia) and other signs of neurologic deterioration. There
- are usually areas of discolored skin (nevi) around the affected eye.
-
- Causes
-
- The exact cause of Wyburn-Mason Syndrome is not known. It may 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
-
- Wyburn-Mason Syndrome is a very rare disorder that affects males more often
- than females.
-
- Related Disorders
-
- Symptoms of the following disorders can be similar to those of Wyburn-Mason
- Syndrome. Comparisons may be useful for a differential diagnosis:
-
- Bonnet-Dechance-Blanc Syndrome is characterized by congenital
- nonmalignant bulges in the veins (aneurysms) of the retina, thalamus, and
- midbrain. It occurs in early childhood and is often accompanied by mental
- deterioration.
-
- Von Hippel-Lindau Disease usually begins during young adulthood but may
- appear as early as the age of eight. It is characterized by headaches,
- dizziness and failure of muscular coordination (ataxia). Unreasonable
- behavior may also occur. Enlarged and twisted blood vessels may occur in the
- retina. Bulges in the blood vessels (aneurysms) may develop. Tumors of the
- adrenal glands may be present as well. (For more information on this
- disorder, choose "Von Hippel-Lindau" as your search term in the Rare Disease
- Database.)
-
- Sturge-Weber Syndrome is a hereditary disorder in which a port wine
- colored stain (angioma) on the face and intracranial abnormalities are
- present at birth. Generalized seizures and additional neurological symptoms
- usually occur between 1-2 years of age. Vascular lesions in the brain
- usually involve the occipital or parieto-occipital regions. (For more
- information on this disorder, choose "Sturge-Weber" as your search term in
- the Rare Disease Database.)
-
- Therapies: Standard
-
- Treatment of Wyburn-Mason is symptomatic and supportive. Surgery may be
- recommended to repair aneurysms of the brain or eye. Genetic counseling may
- be of benefit for patients and their families.
-
- Therapies: Investigational
