Whole Genome Sequencing
Is it time to move beyond the exome?
Is it time to move beyond the exome?
Studies have suggested that up to 15% of disease-causing variants may be found in the non-coding regions of the genome, which are not covered by exome sequencing tests. The PCR-free sequencing methods used in Whole Genome Sequencing (WGS) provide for more uniform coverage across both coding and non-coding regions of DNA. The more uniform coverage offered through WGS can in fact provide better coverage of some regions of the exome than traditional exome sequencing, increasing the possibility of finding a disease causing mutation.
Choose from standard Proband Only and Trio testing options. Parents also have the option of receiving full result reports, if desired.
All of our Whole Genome Sequencing tests as STAT options with a TAT of 10-12 days.
This unique testing option allows providers to combine whole genome sequencing with our StepOne® comprehensive biochemical profile to aid clinical correlation.
Data generation (only) is also available for those physicians and institutions that prefer to do their own genome analysis and report writing.
Supplemental testing options available to complement our full Whole Genome Sequencing test offerings.
PerkinElmer Genomics is one of the first laboratories to offer Whole Genome Sequencing on a clinical basis in effort to maximize clinical diagnostic yield for our clients and patients. Combining superior coverage of the exome (over 98% covered > 20x) with a six week turn-around time, our whole genome sequencing test is designed to maintain the same quality and TAT that clients deserve from an exome sequencing test, while providing access to additional valuable information throughout the genome.
The genome comprises all of a person’s the DNA. The exome, the protein-coding portion of the genome, only accounts for about 1-2% of the genome.
The exome is the part of our DNA that contains protein-coding genes, and accounts for approximately 1-2% of our total amount of DNA (genome).
Whole Genome Sequencing is a genetic test that analyzes all of the DNA in a person’s Genome.
Whole Genome Sequencing could be used in a variety of situations, including:
The literature and research defining the full diagnostic yield of Whole Genome Sequencing is still evolving. However, given that it is estimated that approximately 15% of disease-causing mutations are found in non-coding regions, the yield is expected to be significantly larger than standard Whole Exome Sequencing.
Whole genome sequencing must be ordered by a qualified healthcare provider.
PerkinElmer Genomics’ standard WGS testing options have an average turn-around-time of 6 weeks. STAT testing options are also available to accelerate the delivery of results to patient, and have an average TAT of 10-12 days.
For pricing, please email PerkinElmer Genomics or call us at 1800-419-1400.
PerkinElmer Genomics accepts multiple sample types including Saliva Swabs, Dried Blood Spots, Whole Blood, and Genomic DNA. Please note that DBS are required to perform the StepOne® Biochemical Profile.
All reported variants are confirmed using an orthogonal method.
PerkinElmer Genomics follows the published ACMG guidelines when classifying identified variants.
Yes, a copy of the raw sequencing data can be requested. Individual data will be released on a secure hard drive for a small fee of $150. Requests can be submitted by utilizing our Data Release Form.
Separate parental reports are not included for all TRIO samples. Separate parental reports are an “additional testing option” and must be selected separately on the test requisition form. If selected, each parent must also “Opt In” to which findings they would like to receive in their report.
