Cytogenomics Array Group

What is the Cytogenomics Array Group?

The Cytogenomics Array Group (CAG) began as an informal network of colleagues in North and South Carolina (originally the "Carolinas Array Group") formed to exchange information between laboratories regarding constitutional microarrays and rare case findings. In order to facilitate this exchange, we created a web-accessible database (CAGdb) to house each laboratory’s abnormal cases, which could then be freely shared in a de-identified fashion with all participating laboratories. CNV details, interpretation comments, parental and other follow-up data, and clinical features (all fully stripped of patient identifiers) are collected and shared for each case in this site. This database provides a useful laboratory tool to track experience with in-house microarray cases, network with colleagues, and to share experience with rare findings. Additionally, this resource is meant to facilitate submission to other larger-scale data collections in order to aid in syndrome discovery efforts and make information on rare cases more broadly available. Participating laboratories are encouraged to submit data to NCBI’s ClinVar project (https://www.ncbi.nlm.nih.gov/clinvar) through ISCA data collection (http://www.clinicalgenome.org). With laboratory permission, all cases, or any subset of selected cases, in the CAGdb will be reformatted and submitted to NCBI on that laboratory’s behalf. We encourage participation from any interested laboratories and invite suggestions for improvement of the functionality of the project. This is operated as a non-profit resource through the Fullerton Genetics Laboratory at Mission Health System and is freely available to all participants.
