CdLS Quick Facts


  • CdLS is a genetic syndrome present from birth. There is no cure.
  • CdLS occurs in approximately 1 in 10,000 live births. It affects males and females equally, and is seen in all races.
  • The severity of CdLS ranges from mild to severe, but all individuals with CdLS share similar characteristics, such as small stature, hands, feet, and head; joined eyebrows; long eyelashes; upturned nose; and thin, downturned lips. Physical and cognitive development is delayed. Self-injurious behavior is common, and between 60-70% display some degree of autism spectrum disorder. Speech and language are delayed or absent. Limb differences and/or missing limbs occur in 25% of cases. Common medical problems include gastroesophageal reflux disease, bowel abnormalities, heart defects, seizures, and cleft palate.
  • Since 2004, changes in five different genes have been identified as causing CdLS.
  • In 99% of cases, the gene change that causes CdLS is sporadic, not inherited, which means the change occurs randomly during conception.
  • Researchers estimate there are 20,000 individuals in the U.S. who have CdLS but live without diagnosis and/or support services.
