Variant Interpretation:
What is the protocol for interpreting a variation as a VUS?
Help
Use gene specific databases, HGMD, PubMed
Use gene specific databases, HGMD, PubMed
Are family members with defined clinical status recruited to assess significance of VUS without charge?
Help
Yes.
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
