For all those affected by a rare chromosome disorder.

About CDO

Background - Updated February 2007

CDO was founded in 1992 by a group of seven parents raising children born with rare chromosome disorders. The Alliance of Genetic Support Groups (now the Genetic Alliance) helped CDO get its start that year, and CDO was approved as a member of the National Organization of Rare Disorders (NORD) in 1998.

Our mission: to provide support to parents of children born with rare chromosome disorders, gather together and share information, and to promote research and a positive community understanding of these disorders. CDO envisions a time in the not too distant future when doctors will have a great deal of information available on each and every chromosome disorder. They will be able to tell parents symptoms associated with a particular deletion, duplication or other disorder as well as what not to worry about. It is also our hope that appropriate therapies or other treatments will be recommended specific to particular disorders and that affected individuals will have a much greater chance of a fuller life. This is already beginning to happen and it is CDO’s goal to further support this research in any way possible.

With an extensive library of available up-to-date articles, detailed registry, newsletters, research opportunities, interaction with our medical advisory board, and a listserv that’s online 24 hours a day, CDO is able to provide support and information to families around the world.
