Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
Invitae's variant interpretation methodology adheres closely to ACMG guidelines. Observed variants are interpreted according to the framework of evidence recommended by these guidelines, based on evidence in peer-reviewed literature and Invitae's database. Our clinical report documents the evidence and logic supporting each variant interpretation to make it easy for the … View more

Are family members with defined clinical status recruited to assess significance of VUS without charge? Help
Yes.

Will the lab re-contact the ordering physician if variant interpretation changes? Help
Yes.
