Infantile Hypercalcemia Syndrome in Twins

Abstract

AORTIC hypoplasia and multiple stenoses of pulmonary and systemic arteries occur frequently in patients with supravalvular aortic stenosis (S.A.S.).1 2 3 4 The combination of lesions has been designated "complicated S.A.S."5 or the "S.A.S. syndrome",3 and an association with infantile hypercalcemia has been recognized.3 , 6 7 8 9 A combination of the distinctive facies described by Williams et al.,10 mental retardation, aortic hypoplasia and multiple arterial stenoses without supravalvular aortic stenosis has not previously been described. We report here such an occurrence in identical twins with transient evidence of hypercalcemia in early life.Case ReportTwin girls, J.D. and K.D., were born at full term to apparently . . .
