What are the signs and symptoms of Cornelia de Lange syndrome?

The signs and symptoms of Cornelia de Lange syndrome (CdLS) vary widely among affected people and can range from relatively mild to severe. Affected people may experience:[1][2]
  • Slowed growth before and after birth
  • Intellectual disability
  • Developmental delay
  • Autistic and/or self-destructive behaviors
  • Skeletal abnormalities of the arms and hands
  • Gastrointestinal problems
  • Hirsutism (excess hair growth)
  • Hearing loss
  • Myopia
  • Congenital heart defects
  • Genital abnormalities (i.e. cryptorchidism)
  • Seizures

Affected people typically have distinctive craniofacial features, as well, which may include microcephaly; arched eyebrows that often grow together in the middle (synophrys); long eyelashes; low-set ears; small, widely spaced teeth; and a small, upturned nose.[1][2]

The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature.

The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined.

Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
