Chromosome Deletion Outreach, Inc. is a non-profit organization, founded, supported, and run by parents just like you. Our children are affected by a wide range of chromosome disorders, including deletions, duplications, trisomies, inversions, translocations, and rings.

Sometimes these disorders are so unusual that doctors tell us, “You’re the only one out there.”

We’ve been helping each other for over twelve years. Our families live around the world and CDO provides a network of support and information through an extensive library of available up-to-date articles, detailed registry, newsletters, and a listserv that’s online 24 hours a day, everyday.

Please join us. Your support of CDO will help promote research and a better understanding of our children’s rare chromosome disorders.
