Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
Use gene specific databases, HGMD, PubMed

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. Whenever the status of a genetic variation is changed we will contact the requesting professional if he/she is not available the department will be contacted
