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). If the variation cannot be placed into a pathogenic or non-pathogenic state, further studies including evaluation of family members and/or assessing … 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. They must contact us and want further information if they act on behalf of the patient

Tests performed
Entire test performed in-house
Analytical Validity: Help
PCR-based sequencing detects 99% of the reported mutations in the CFH, CFI, CFB, CFHR5, CD46, C3, APLN & THBD genes. The sensitivity of DNA sequencing is over 99% for the detection of nucleotide base changes, small deletions, insertions and indels in the region analyzed.
