Chromosome Disorder 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.” But now using our newly introduced web application we have the capability to specifically categorize chromosomal karyotypes and finally begin to understand more about the genes involved in each rare chromosome rearrangement. We hope to eventually improve specifically tailored treatments to help affected individuals.
