Cornelia de Lange syndrome in children

Abstract

Cornelia de Lange syndrome is a multisystem malformation syndrome recognized primarily on the basis of characteristic facial dysmorphism, including low anterior hairline, arched eyebrows, synophrys, anteverted nares, maxillary prognathism, thin lips, «carp» mouth, in association with prenatal and postnatal growth retardation, mental retardation and, in many cases, upper limb anomalies. However, there are clinical options with milder phenotypes in this syndrome. The prevalence of the syndrome is 1:10,000-30,000 live births, occurs equally, regardless of gender. Although this syndrome is considered rare, experts agree that it is likely underdiagnosed.
