Indications

This test may be a useful screening tool for patients with developmental delay, or with one or more overlapping features suggestive of one of the represented epigenetic signature conditions or imprinting disorders.

Methodology

Methylation array

Detection

Methylation abnormalties detected using this test may require additional targeted testing to confirm and further
characterize the underlying genomic abnormality. This test will not detect females with Fragile X (FMR1) expansions.

Specimen Requirements

4-6 ml of peripheral blood collected in an EDTA (lavender top) tube is the required specimen type. The minimal blood needed for reliable DNA isolation is 3 ml. Extracted DNA or banked is also accepted for this test given the original specimen was whole blood collected in an EDTA tube.

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.

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...
