About Cornelia De Lange Syndrome Awareness Day
Cornelia de Lange syndrome (CdLS) is characterized by slow growth before and after birth leading to short stature; intellectual disability that is usually moderate to severe; and abnormalities of bones in the arms, hands, and fingers.
CdLS occurs in approximately 1 in 10,000 live births. It affects males and females equally, and is seen in all races.
The syndrome is named after Dutch pediatrician Cornelia Catharina de Lange, who described it in 1933.
