There is no cure for Williams syndrome. Treatment is symptomatic and supportive. Individuals with Williams syndrome need regular monitoring for potential medical problems by a physician familiar with the disorder.  Specialized services and therapies are also recommended to help individuals with WS maximize their potential.


Research Update: "Early research suggested that an inversion of the genes in the WS critical area could result in a pattern of problems which resembles Williams syndrome (so-called "atypical Williams syndrome"). However, recent research of individuals with an inversion who were at one time diagnosed as having Williams syndrome (including the individuals referred to in the original article by Osborne et al.), shows that although several of the people had mental retardation and/or ADHD, none of them shared any traits that are specific to WS.  It is also now known that 28-35% of transmitting parents have inversions as do 6-7% of nontransmitting parents (an estimate of the inversion rate in the general population). These parents definitely do not have a pattern of problems that resembles Williams syndrome.

With this new research in mind, it is important to stress that WS is a genetic diagnosis.  In greater than 98% of cases, an individual who does not have the elastin deletion does not have Williams syndrome."

The resources below are intended to help physicians treating children with Williams syndrome get oriented to the special conditions, developmental milestones and medical needs of these individuals.
