How does Cytogenetic Microarray testing work?
Our analysis includes use of DNA microarray technology to detect possible imbalances in over 150 regions of common microdeletion / microduplication syndromes, all subtelomeric regions, the pseudoautosomal regions, and across the genome. Microarray is completed using the the Infinium® Assay with Illumina® HumanCNV610-quad DNA Analysis BeadChip platform. This SNP array includes DNA from over 610,000 markers (copy number or SNP) covering all 24 chromosomes. Using Illumina GenomeStudio™ analytical software, differences in copy number of different DNA clones can be detected. Imbalances detected may be confirmed by FISH analysis.
