Indications

Molecular testing is useful to confirm the diagnosis and to identify the disease causing mutations within a family to allow for carrier testing and prenatal diagnosis.

Methodology

Sanger sequencing

Please note FGFR3 testing is not offered as a panel. You must specify which condition is clinically suspected. Testing for each condition must be ordered individually and will be billed separately. If you request more than one test, please specify the order in which they should be run or if they should be run simultaneously.

Specimen Requirements

The preferred sample type is peripheral blood collected in an EDTA (purple top) tube – at least 2-3ml for pediatric patients and 5-6ml for adult patients. Extracted DNA, dried blood spots, and saliva are also accepted for this test. Saliva samples must be submitted in an approved saliva kit. Contact the lab to receive a saliva kit or to have one sent to your patient.

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.

Prenatal Testing Information

Prenatal diagnosis is available if the familial mutations are known or there are clinical features identified via ultrasound suggestive of a diagnosis in the fetus. Additional fees for cell culture and maternal cell contamination may apply. Maternal cell contamination studies are required for all prenatal molecular tests. Contact the laboratory prior to sending a prenatal specimen.

Meet The Jones Family

Meet The Jones Family

The journey to becoming parents did not start as an easy one for my husband and I. We suffered the heartache of miscarriage and the unimaginable pain of burying our first born child. Our son, sweet 1 lb 1.4 ounce, 12 inches long, teeny, tiny little Joseph “Hamilton” Jones was born with spina bifida, hydrocephalus, and a heart defect. It tore our hearts out leaving the hospital without him, knowing our dreams and hope for the future were shattered. ...
