Test purpose: Help
Diagnosis; Mutation Confirmation; Screening
Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
Missense and silent changes unknown to the HGMD database and to SNP databases (SNP137, 1000 genomes)

Are family members with defined clinical status recruited to assess significance of VUS without charge? Help

Will the lab re-contact the ordering physician if variant interpretation changes? Help
