Whole-Genome SNP Microarray: Cytoscan HD Microarray

Test Information

The Affymetrix CytoScan HD platform allows for genome-wide detection of copy number gains and losses. In addition to detection of copy number variations (CNVs), this SNP array also allows for the analysis of loss of heterozygosity (LOH) which can be useful in identifying uniparental disomy (UPD) as well as autozygosity (identity by descent).

Specimen Requirements

5 to 7 ml of peripheral blood collected in an EDTA (lavender top) tube is the preferred specimen type. The minimal blood needed for reliable DNA isolation is 3 ml.

Additional specimen types include: saliva, extracted DNA, and solid tissue. Please contact the lab for more details.

Transport Instructions

The specimen should be kept at room temperature and delivered via overnight shipping. If shipment is delayed by one or two days, the specimen should be refrigerated and shipped at room temperature. Do not freeze the specimen. Samples collected on Friday can be safely designated for Monday delivery.

Lucy's Story

Lucy's Story

When our daughter Lucy had a metabolic crisis at 7 days old, we were shocked and devastated to find out that she was born with a rare genetic disorder (MSUD). Her newborn screening results did not make it back in time to prevent the crisis, and no one at our local hospital was familiar with the disease. They did not know how to treat her. Calls were made to Greenwood Genetic Center to confirm her diagnosis...
