Cornelia de Lange syndrome (CdLS) is characterized by distinctive facial features, growth retardation, developmental delay, hirsutism, and limb abnormalities. Craniofacial features include synophrys, arched eyebrows, long eyelashes, small upturned nose and thin downturned lips, small widely spaced teeth, and microcephaly.

Additional findings may include cardiac defects, gastrointestinal dysfunction, hearing loss, myopia, seizures, cleft palate, and cryptorchidism or hypoplastic genitalia.

The prevalence of disorder is estimated at 1:50,000 for the classic form of CdLS. CdLS can be inherited in an autosomal dominant or X-linked manner.
