CDO Database Registry
Please click on any of the links below to access CDOs complete list of registered chromosomal karyotypes. Our registry is designed to update automatically when a new member joins CDO so the information you see is always current. Please do not be discouraged if the chromosomal karyotype you are searching for is not listed. New members are joining CDO daily and it is possible we will be able to connect you with another individual or family very soon.
If you have not yet joined CDO, please consider registering. Each new member application helps individuals, families, physicians and researchers learn more about these very rare chromosome disorders.
Physicians, researchers and other medical and developmental professionals are most welcome to join CDO too. Submit your research study details for addition to our website by e-mailing info@chromodisorder.org
Please note: Use the drop down menu first to select the chromosome number, then choose Deletion, Duplication, Insertion etc.
