Williams-Beuren syndrome (WBS) is a rare autosomal dominant multisystem disorder associated with the hemizygous deletion of a number of genes on chromosome 7q11.23. The range of phenotypes may include congenital vascular and heart disease, characteristic facial features, premature aging, generally mild mental retardation, short stature, myopathy, hypercalcemia, and a unique cognitive profile. To date at least 28 genes have been identified within the deleted region.
