The Cornelia de Lange Syndrome (CdLS) Foundation provides a host of services for anyone touched by this little-known genetic syndrome and other isolating conditions.

If CdLS is Part of Your Life, We’re Here to Help

CdLS occurs in approximately 1 in 10,000 live births and the CdLS Foundation is honored to currently serve over 2,800 individuals with this rare genetic syndrome.

We also aim to reach the thousands more who live without a diagnosis and/or are unaware of services available to them. If you or someone you know would benefit from our many support services, please let us know!
