Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
Our lab has created a variant classification system which is based on the American College of Medical Genetics and Genomics guidelines (Genet Med. 2015 May;17(5):405-24).

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
Decline to answer.
