Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
Variants are identified and evaluated using a custom collection of bioinformatic tools and comprehensively interpreted by our team of directors and genetic counselors.

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