-
-
- Individuals with Cornelia de Lange Syndrome greatly resemble each other.
- Major characteristics include skeletal and facial abnormalities, excessive
- hairiness and severe mental retardation.
-
- Symptoms
-
- Newborns with Cornelia de Lange Syndrome have low birth weight (under 5
- pounds) and feeding difficulties. The typical features of Cornelia de Lange
- Syndrome include a small head (microcephaly); a small, broad nose; thin,
- downturned lips; thick, bushy eyebrows; and long eyelashes. A cleft palate
- may occur. Generally the hands and feet are small. Limb abnormalities may
- include the absence of the upper portion of one or more limbs (phocomelia) or
- the absence of one or more of the fingers or toes (oligodactyly). Other
- characteristics may include excessive hair on the body (hirsutism), hearing
- loss, seizures, and cardiac and gastrointestinal abnormalities. Commonly
- people with Cornelia de Lange Syndrome are short. Mental retardation may be
- severe and speech may be impaired.
-
- Cause
- In the majority of cases of Cornelia de Lange Syndrome, the cause in not
- known (sporadic). It is suspected that some cases may be genetic in origin.
- It has been suggested that some cases of this syndrome may be inherited as an
- autosomal dominant trait. It is possible that the gene responsible for this
- syndrome is located on the long arm of chromosome 3.
-
- 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
-
- Cornelia de Lange Syndrome affects males and females in equal numbers. There
- is a 2 to 4 percent rate of recurrence within families. The syndrome is
- estimated to occur in between 1:10,000 and 1:30,000 births.
-
- Therapies: Standard
-
- Treatment of Cornelia de Lange Syndrome is symptomatic and supportive.
- Genetic counseling may be of benefit for patients and their families.
- Physical therapy, occupational therapy, special education services,
- artificial limbs and hearing aids may be provided on an individual basis as
- needed.
-
- Therapies: Investigational
-
- An effort is being made to document individuals diagnosed as having Cornelia
- de Lange Syndrome. It is hoped that the maintenance of files with
- photographs, examination results and family histories may lead to an
- understanding of the genetic basis of this syndrome.
-
- 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.
