title: Costello syndrome: a postnatal growth retardation syndrome with distinct phenotype.
abstract: In this report we describe two non-related patients, a 12-year-old girl and 3 6/12-year-old boy, with Costello syndrome. Costello syndrome is a true MCA/MR syndrome with severe postnatal growth retardation as the first clinical sign. Characteristic facial changes, loose, hyperelastic skin and papillomata become progressively more evident with age. Patients with Costello syndrome present a pleasant, happy nature and are mildly to moderately mentally retarded.
