Variant Interpretation:
What is the protocol for interpreting a variation as a VUS?
Help
Interpretation and classification of clinical significance of the detected variant are based on catalogued information from the NCBI ClinVar database (http://0-www-ncbi-nlm-nih-gov.brum.beds.ac.uk/clinvar/variation/), LOVD database (http://databases.lovd.nl/ shared/genes/) and other locus specific databases as well as information from published literatures

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?
