Variant Interpretation:
What is the protocol for interpreting a variation as a VUS?
Help
Constitutional copy number variants (CNV) detected in the Genomic Microarray (GMA) Laboratory at ARUP Laboratories go through a standardized, comprehensive evaluation and classification process. This process was developed using guidance provided by the American College of Medical Genetics and Genomics (ACMG)

Analytical Validity:
Help
For known abnormalities with sufficient coverage on the array platform, sensitivity and specificity exceeded 95%; however, as this is a whole genome technology, all regions of the genome that are covered by this technology could not be evaluated as all true positives and true negatives are not known. Therefore, specificity …
