Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
Variants are identified and evaluated using a proprietary collection of bioinformatic tools and comprehensively interpreted.

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

Entire test performed in-house
Analytical Validity: Help
Greater than 99% sensitivity and specificity based on CAP proficiency testing
Assay limitations: Help
The assay will not consistently detect germline mosaicism below 50% or rule out the presence of large chromosomal aberrations, including rearrangements, inversions that do not change copy number of genomic regions. The assay does not detect repeat expansions. Possible intergenic variant interactions are not commented on. False positive or false … View more
