Definition of Williams syndrome
Williams syndrome is a rare genetic disorder that can lead to problems with development.
Causes, incidence, and risk factors
Williams syndrome is a rare condition caused by missing genes. Parents may not have any family history of the condition. However, a person with Williams syndrome has a 50% chance of passing the disorder on to each of his or her children. The cause usually occurs randomly.
Signs and tests
There is no cure for Williams syndrome. Avoid taking extra calcium and vitamin D. Treat high levels of blood calcium, if present. Blood vessel narrowing can be a significant health problem and is treated based on its severity.
About 75% of those with Williams syndrome have some mental retardation.
