Williams syndrome is a disorder of unknown etiology with a characteristic facial appearance, vascular disease and infantile hypercalcemia. Most cases are sporadic. We report the case of a dizygotic male twin with the Williams syndrome. This appears to be the first report of twins with only one affected. This suggests a mutational event as the cause of Williams syndrome.
