What is Williams Syndrome?
Williams syndrome is a rare, congenital (present at birth) disorder characterized by physical and developmental problems including an impulsive and outgoing (excessively social) personality, limited spatial skills and motor control, and intellectual disability (i.e., developmental delay, learning disabilities, mental retardation, or attention deficit disorder). Other features include characteristic "elfin-like" facial features, heart and blood vessel problems, hypercalcemia (elevated blood calcium levels), low birth weight, slow weight gain, feeding problems, irritability during infancy, dental and kidney abnormalities, hyperacusis (sensitive hearing), and musculoskeletal problems. Symptoms vary among patients. Although individuals with Williams syndrome may show competence in areas such as language, music, and interpersonal relations, their IQs are usually below average, and they are considered moderately to mildly retarded. Scientists have learned that most individuals with Williams syndrome have a deletion of genetic material on chromosome 7. This probably causes the physical and developmental problems experienced by patients.
Is there any treatment?
There is neither a cure for Williams syndrome nor a standard course of treatment. Treatment is symptomatic and supportive. Individuals with Williams syndrome need regular monitoring for potential medical problems by a physician familiar with the disorder, as well as specialized services to maximize their potential.
What is the prognosis?
The prognosis for individuals with Williams syndrome varies. Some may be able to master self-help skills, complete academic or vocational school, and live in supervised homes or on their own, while others may not progress to this level.
