Clinical Information
Test purpose: Help
Diagnosis; Mutation Confirmation; Pre-symptomatic; Screening
Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
Identified variants are documented in-house and are comprehensively evaluated using mutation databases and literature by scientific and medical directors.

Will the lab re-contact the ordering physician if variant interpretation changes? Help
Yes.
Recommended fields not provided:
Clinical validity, Clinical utility, Target population, Are family members with defined clinical status recruited to assess significance of VUS without charge?, Is research allowed on the sample after clinical testing is complete?, Sample negative report, Sample positive report
Technical Information
Test Procedure: Help
Stepwise approach: 1.) MAPT: Sequencing of the exons 1, 2 and 9-13. 2.) MAPT: MLPA for deletion/duplication analysis. 3.) GRN: Sequencing of the entire coding regions and flanking non-coding sequences. 4.) GRN: MLPA for deletion/duplication analysis.
