The Northwest Clinical Genomics Laboratory (NCGL) offers targeted analysis for variants previously identified in our laboratory. Known pathogenic variant testing should be selected if such a variant was previously identified in the family by the NCGL (we tested a relative of the patient) and we have a positive control for that patient.
Sanger Sequencing: The coding exon and flanking intron sequences known to contain the variant are amplified by PCR in a single reaction and then sequenced by automated sequencing.
BLOOD IS PREFERRED.
BLOOD: 2 EDTA (purple top) tubes
Whole blood may be stored up to 5-7 days in the refrigerator before shipping.
Single site (known familial mutation or variant): 5 µg DNA
Oragene Saliva samples are accepted
How to Order
It may be helpful for the clinician to phone or contact us to discuss the patient with the the genetic counselor, Dru Leistritz (206-543-5464 or firstname.lastname@example.org), to determine if testing is appropriate and which test to select. After selecting the test, please follow these steps to order it:
1. Complete Required Forms
2. Complete Billing Information (third page of Requisition Form)
3. Collect Specimen
4. Ship specimen to NCGL
