Williams-Beuren syndrome is a rare disease. Characterized by clinically mild or moderate mental retardation, aortic supravalvular stenosis, hipercalcemia and typically dismorphic elfinlike faces. The syndrome is due to a genetic disorder, generally deletion of the long arm of chromosome 7 (7q11.23), producing loss of gene codification for elastin. Every case is produced of new, when it is inherited it does so as an autosomic dominant character.

Palabras clave : Williams syndrome; mental retardation; aortic valve stenosis; elastin; chromosome 7.
