Test Description

This test involves targeted sequencing, analysis, and interpretation of a single variant or known familial mutation by an appropriate technology (ex. Sanger sequencing).

Test Methods and Limitations

Only amplification of the regions of the gene in which the targeted variant is located is performed; other regions of the gene are not analyzed. The products are sequenced in the forward and reverse directions. Nucleotide numbering is based on GenBank accession number; nucleotide 1 corresponds to the A of the start codon ATG.

This analysis cannot detect single and multi-exon deletions and duplications, or variants in regions not analyzed. This assay is not designed to detect mosaicism; possible cases of mosaicism may be investigated at the discretion of the laboratory director.

Variants are evaluated by their frequency as reported in public databases such as the Genome Aggregation Database (gnomAD), Human Gene Mutation Database (HGMD), and ClinVar. Variants that have a frequency greater than expected given the prevalence of disease are considered to be benign. In some cases, due to the complexity of the sequence, not all variants in the flanking intronic regions are able to be analyzed. The interpretation of variants is based on our current understanding of the genes involved. This understanding may change over time as more information becomes available.

DNA, Isolated
Test Details Page
Collection

Required DNA Quantity by Test Type*:

  • Next Generation Sequencing (NGS): Send >1000 ng total gDNA @ >15 ng/μL. Please ship samples in 10mM Tris. Do not use EDTA.
  • Sanger Sequencing: Send >500 ng total gDNA @ >15 ng/μL (varies by the size of the gene and the variants requested).
  • Non-Sanger Sequencing Tests: Send >500 ng total gDNA @ >15 ng/μL.
Sample Condition * Required DNA Quality: High molecular weight DNA (>12kb). A260/A280 reading should be ≥ 1.8. A260/230 a ratio range of 1.8 to 2.2. Contact the laboratory for specific amounts if total ng cannot be met.
Shipping Ship overnight at ambient temperature.
Special Sample Instructions
  • Research Laboratories: DNA extracted in research laboratories is not acceptable. Only under exceptional circumstances (e.g., proband not available) will DNA extracted in a research laboratory be accepted for clinical testing. Additional testing (e.g., of other family members) may be required to confirm results.
  • Laboratories outside the United States: Non-US laboratories are not subject to CLIA regulations and will be reviewed on a case-by-case basis. Please call to speak with a laboratory genetic counselor before submitting a DNA sample from any non-CLIA-certified laboratory.
  • Special Notes: If extracted DNA is submitted, information regarding the method used for extraction should be sent along with the sample.
Dried Blood Spots
Test Details Page
Collection Container(s) Dried blood spot card
Collection

Follow kit instructions. Briefly, allow blood to saturate the card until indicated areas are filled and blood has soaked through the card. Air dry the card at ambient temperature for at least 3 hours.

  • NBS: Please contact Revvity Omics to request the StepOne® kit.
  • Gene Sequencing: Please contact Revvity Omics to request the DBS collection kit.
  • For pre-punched DBS: The required minimum is 6 punches
Sample Condition Follow the instructions provided with the collection set. Store the dried blood at ambient temperature for up to two days. If the specimen cannot be sent as soon as it is dry, the filter paper should be placed in a sealable plastic bag and stored in a refrigerator (≤ 8°C) or preferably in a freezer.
Shipping Follow kit instructions. Double bag and ship overnight at ambient temperature.
Saliva
Test Details Page
Collection Container(s) Oragene™ Saliva Collection Kit or ORAcollect-Dx kit
Collection Collect saliva on an Oragene™ Saliva Collection Kit ORAcollect-Dx kit according to the manufacturer's instructions.
Sample Condition Store at ambient temperature. Do not refrigerate or freeze.
Shipping Ship overnight at ambient temperature.
Special Sample Instructions Please contact Revvity Omics to request the saliva collection kit for patients who cannot provide a blood sample as whole blood is the preferred sample. Testing using Saliva swabs is currently not available for customers in India. Contact the Revvity Omics laboratory for more information.
Whole Blood (EDTA)
Test Details Page
Collection Container(s) EDTA (purple top)
Collection Infants (< 2-years): 2 to 3 mL; Children (>2-years): 3 to 5 mL; Older children and adults: Minimum 5mL. The blood tube should be inverted several times immediately after blood collection to prevent coagulation.
Sample Condition Store at ambient temperature. Do not refrigerate or freeze.
Shipping Ship overnight at ambient temperature ensuring receipt within 5-days of collection.
Special Sample Instructions Clotted or hemolyzed samples are not accepted.
