Abstract

Cornelia de Lange syndrome is a rare autosomal dominant or X-linked developmental disorder characterized by characteristic facial dysmorphism, intellectual disability, growth retardation, upper limb and multiorgan anomalies. Causative mutations have been identified in five genes coding for the cohesion complex structure components or regulatory elements. Among them, RAD21 is associated with a milder phenotype. Very few RAD21 intragenic mutations have been identified so far. Thus, any new patient is a valuable tool to delineate the associated phenotype. We discuss a new patient with RAD21 confirmed molecular diagnosis and compare his clinical features to those of previously described patients carrying different RAD21 intragenic mutations.
