-
- Jackson-Weiss Syndrome is a rare disorder inherited as an autosomal
- dominant genetic trait. This disorder is characterized by permanent
- premature closure of the bones of the skull (craniosynostosis) along with
- abnormalities of bones in the face and feet. Typically the deformities of
- the feet include fusion of the bones of the upper foot along with malformed
- great toes. Symptoms of this disorder can vary within a family from mild to
- severe.
-
- Symptoms
-
- Jackson-Weiss Syndrome is a rare disorder in which the symptoms may vary from
- mild to severe. The most common symptoms that have been found in affected
- patients include: premature closure of the bones of the skull
- (Craniosynostosis); an underdeveloped jaw; widely spaced eyes
- (hypertelorism); down-slanting eyes; drooping eyelids (ptosis); crossed eyes
- (strabismus); abnormalities of the outer ear; a flat bridge of the nose; a
- beaked nose; failure of the upper jaw bones to properly fuse together causing
- an opening in the roof of the mouth (cleft palate); a high arched palate;
- and/or an accumulation of fluid in the skull (hydrocephaly). (For more
- information on these disorders choose "Craniosynostosis" or "Hydrocephalus"
- as your search terms in the Rare Disease Database).
-
- Premature closure of the bones of the skull (craniosynostosis) may cause
- disturbances in vision, headaches and/or excessive pressure within the skull.
-
- Other symptoms that have been found in some patients with Jackson-Weiss
- Syndrome include: fingers and/or toes that may be webbed (syndactyly),
- short, bent abnormally or may have bones missing; limited joint movement;
- mental retardation; and/or a condition in which the knees are close together
- with the ankles widely spaced (genu valgum).
-
- Causes
-
- Jackson-Weiss Syndrome is a rare disorder inherited as an autosomal dominant
- genetic trait with incomplete penetrance. Symptoms varying from mild to
- severe.
-
- 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.
-
- Incomplete penetrance means that all characteristics of a particular
- trait may not be manifested in all those who inherit the gene.
-
- Affected Population
-
- Jackson-Weiss Syndrome is a very rare disorder that affects males and females
- in equal numbers. There have been over one hundred and thirty cases of this
- disorder reported in the medical literature.
-
- Related Disorders
-
- Symptoms of the following disorders can be similar to those of Jackson-Weiss
- Syndrome. Comparisons may be useful for a differential diagnosis:
-
- Apert Syndrome is a rare disorder inherited as an autosomal dominant
- genetic trait. This disorder is characterized by fused or webbed fingers and
- toes (syndactyly), a pointed head (acrocephaly or oxycephaly), other skeletal
- and facial abnormalities, and mental retardation. (For more information on
- this disorder, choose "Apert Syndrome" as your search term in the Rare
- Disease Database).
-
- Carpenter Syndrome is a rare disorder inherited as an autosomal recessive
- genetic trait. This disorder is characterized by an unusual shape of the
- head (oxycephaly) as well as deformities of the hands (branchysyndactyly) and
- feet (preaxial polydactyly). (For more information on this disorder, choose
- "Carpenter Syndrome" as your search term in the Rare Disease Database).
-
- Crouzon Disease is a rare disorder inherited as an autosomal dominant
- genetic trait. Symptoms of this disorder may be: abnormalities of the skull,
- face and brain due to premature closure of the bones of the skull; swelling
- of the optic disk inside the eye; impaired vision; hearing loss; a beaked-
- shaped nose; an underdeveloped lower jaw; and/or a high arched palate. (For
- more information on this disorder, choose "Crouzon Disease" as your search
- term in the Rare Disease Database).
-
- Pfeiffer Syndrome is a rare disorder inherited as an autosomal dominant
- genetic trait. This disorder is characterized by a short, pointed head
- (acrobrachycephaly) and abnormalities of the face, jaws and teeth. Webbed
- fingers or toes (syndactyly) and other abnormalities of the thumbs and big
- toes may also occur. Symptoms can vary from mild to severe. (For more
- information on this disorder, choose "Pfeiffer Syndrome" as your search term
- in the Rare Disease Database).
-
- Saethre-Chotzen Syndrome is a rare disorder thought to be inherited as an
- autosomal dominant genetic trait. This disorder is characterized by a small
- head (microcephaly), premature closure of the bones of the skull
- (craniosynostosis), mildly fused webbed fingers and/or toes (syndactyly), and
- facial abnormalities. (For more information on this disorder choose
- "Saethre-Chotzen Syndrome" as your search term, in the Rare Disease
- Database).
-
- Therapies: Standard
-
- Patients with Jackson-Weiss Syndrome may benefit from surgery to correct the
- craniosynostosis, cleft palate, and/or abnormalities of the hands and feet.
-
- Speech therapy may be needed when cleft palate is present.
-
- Genetic counseling may be of benefit for patients and their families.
- 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.
