Target population: Help
Solid tumors with metastatic disease or not; FFPE samples with greater than or equal to 30% neoplastic content
Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
If a variant is uncharacterized or listed as unknown in the knowledgebases with no other functional studies identified, and is not classified in ClinVar for the patient's tumor type, the molecular impact is classified as unknown.

Are family members with defined clinical status recruited to assess significance of VUS without charge? Help
No.

Will the lab re-contact the ordering physician if variant interpretation changes? Help
No. The lab does not re-contact the ordering physicians as routine practice.

Laboratory's policy on reporting novel variations Help
Novel variants are interpreted in the context of the patient’s disease according the AMP/ASCO/CAP guidelines in which the variant is given a tier classification to signify the level of scientific literature associated with therapeutic, prognostic, and/or diagnostic evidence. All detected variants are reported on a clinical laboratory report that is … View more
