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 interpretation of a variation as a VUS is done according to the practice guidelines provided by the American College of Medical Genetics (ACMG; ACMG recommendations for standards for interpretation and reporting of sequence variations).
- 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.
- ALAMUT, integrating other programs (Polyphen-2, Mutation Taster, Alignment, ExPASy, BLAST) .
- 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).
- Centogene has a common practice to report all variants found in genetic testing, including novel and previously reported variants. A number of criteria are used to support a variant as being potentially disease-causing, including segregation with disease status in other affected family members, absence from a control population, and location in a conserved amino acid sequence. Evidence of altered gene function is ideally required to confirm pathogenicity, however this type of supporting evidence
- 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?)
- No, We are performing a majority of carrier testing with reduced pricing and in selected cases at no cost.
- 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, In case of identification of mutation that can be present in non-affected family members, or after identification of highly specific genetic change, or in additional special situations we could contact the ordering physician again.
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.)
- After clinical testing is completed, with the patient’s signed consent, Centogene utilizes and archives the sample according to all regulatory guidelines and standards.
