Variants Of Unknown Significance (VUS) Policy And Interpretation
- What is the protocol for interpreting a variation as a VUS? HelpDescription of how the laboratory handles Variants of Unknown Significance. This may be a general statement for the laboratory and not specific to this test.
- The PreventionGenetics protocol for interpreting sequence variants has been carefully developed over a period of 10 years. We are conservative in our interpretations. We do not label a variant as pathogenic or benign without conclusive evidence. Although we use a variety of software to assist us in interpretation, we rely primarily on evidence published in the literature, on control allele frequencies (especially from the 1000Genomes and Exon Sequencing Project), and on genetic evidence. Programs that predict pathogenicity or splicing are given much less weight.
- What software is used to interpret novel variations? HelpList of the software applications that the lab uses to interpret novel variants. Examples for medical molecular genetics interpretation include: Melina II, MEME Suite, VISTACartagenia Bench, Alamut, SIFT, PolyPhen, Align-GVGD, GeneSplicer, laboratory proprietary internal software.
- GeneSplicer, Human Splicing Finder, MaxEntScan, Mutation Taster, NNSPLICE, PolyPhen 2, SIFT and Splice Site Finder.
- What is the laboratory's policy on reporting novel variations? HelpDescription of how the lab reports novel variations, it may include who gets contacted and how (ex. person ordering the test will be contacted via telephone as soon as VUS is identified).
- Sequence variants found in our patients are contributed to ClinVar. Anonymous patient sequence data will also be shared with researchers for preparation of peer-reviewed publications.
- Are family members with defined clinical status recruited to assess
significance of VUS without charge?HelpDoes the laboratory offer testing for a variant of unknown significance to family members, free of charge? (Is test offered to affected individuals and/or presumed obligate carriers to help determine clinical significance of a VUS?)
- Yes, Please visit our website for details at https://www.preventiongenetics.com/forms.php for Targeted variant tests.
- Will the lab re-contact the ordering physician if variant interpretation
changes? HelpDescription of laboratory procedures to monitor and address reinterpretation of genetic tests results over time, after issuing the report. Does laboratory systematically re-evaluate prior interpretations and generate new reports, or does the person ordering the test need to periodically recontact the labortory to inquire about changes in test interpretation?
- Yes, Please visit our website for details http://preventiongenetics.com/
Research
- Is research allowed on the sample after clinical testing is
complete?HelpAfter clinical testing is complete, does the laboratory perform any research testing using the submitted specimen? (Quality control is not considered as research for this question.)
