» What are the features that go together to make Cornelia de Lange Syndrome?

There are four main features in this syndrome. Children with CdLS are small at birth and remain small compared to children of the same age. They are all slow learners but this varies from mild to severe. Most children have limb abnormalities which range from extremely small hands to complete absence of forearms. The most striking feature of the syndrome is that all the children are alike, like brothers and sisters.
