Abstract: The Williams syndrome is a sporadic disorder generally characterized by a peculiar pattern of craniofacial abnormalities (elfin facies), prenatal and postnatal growth deficiency, mental retardation, variable congenital heart disease (including supravalvular aortic stenosis), and occasionally infantile hypercalcemia.1 Its etiology, pathogenesis, and possible relationship to vitamin D and calcium metabolism have not as yet been determined.2 Previous reports of children with this syndrome make reference to their overall mental retardation as determined by IQ as measured by various psychological tests.1,3 Frequent mention is also made of these children9s tendency to an unusual, outgoing personality.1,3 Other observers describe a unique type of mental deficiency with poor motor coordination but an unusual command of language, often resulting in a superficial overestimation of cognitive abilities.3
