Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
Identified variants are documented in-house and are comprehensively evaluated using mutation databases and literature by scientific and medical directors.

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