Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
Tempus uses an internally-built proprietary algorithm based on ACMG/AMP/ASCO guidelines for variant classification. Variants are reported in a tiered structure based on classification and therapeutic actionability. Variants with insufficient evidence to be classified as either pathogenic, likely pathogenic, likely benign or benign are classified as Variants of Uncertain Significance (VUS). … View more

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.
