Variants Of Unknown Significance (VUS) Policy And Interpretation

What is the protocol for interpreting a variation as a VUS? Help
VUS and novel variants will be interpreted by trained lab team member and a lab director using current medical literature and databases
What is the laboratory's policy on reporting novel variations? Help
Unusual or clinically significant novel variants will be communicated to the ordering provider via telephone call or email communication.
Are family members with defined clinical status recruited to assess significance of VUS without charge?Help
No
Will the lab re-contact the ordering physician if variant interpretation changes? Help
Yes, No systemic re-evaluation of previously reported variants/findings are currently performed. However, if the same variant/finding is identified in another patient and current assessment results in change in variant classification/interpretation, then the laboratory will recontact the ordering provider and issue an updated report.
