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

Entire test performed in-house
Analytical Validity: Help
PCR-based sequencing detects 99% of the reported mutations in the CLN1, CLN2, CLN3, CLN5, CLN6, CLN7, CLN8 and CLN10 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.
