GeneDx offers full-service molecular cytogenetic testing, including a custom-designed whole-genome array CGH test. In addition, an economical targeted array CGH test is available to rule out 65 common or novel genomic disorders as well as terminal and pericentromeric chromosomal rearrangements. Supplementing these tests is a FISH service that can be requested as a stand-alone test for genomic disorders or specific segmental aneuploidies, or as a follow-up test for parents of a proband with a positive array CGH result.
GeneDx also offer prenatal array CGH testing. For more information, click

The ISCA consortium
GeneDx participates in the International Standard Cytogenomic Array (ISCA) consortium. Anonymized array CGH data and clinical information may be submitted to a HIPAA-compliant, de-identified database as part of the National Institutes of Health's effort to improve diagnostic testing and enhance our understanding of the relationships between genetic changes and clinical symptoms. Visit the consortium website
here. Confidentiality and full anonymity of each submission is maintained. Please use the current GeneDx molecular cytogenetics test requisition and consent forms when requesting testing. If these GeneDx forms are not sent with the submitted specimen, array data will be anonymized and submitted to the ISCA database. If you wish not to have genomic information derived from your submitted sample sent to the database, please email
