Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
Novel variations are evaluated using a variety of algorithms including splice site analysis, sequence conservation within species and isoforms and functional estimation (i.e. SIFT, Polyphen, AlignGVGD & Mutation Taster), in addition to allele frequency in population controls and published literature. If the variation cannot be placed into a pathogenic or … View more

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
No.
