Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
Variants are categorized as pathogenic, likely pathogenic or a variant of uncertain significance (VUS) utilizing the American College of Medical Genetics and Genomics (ACMG)/Association for Molecular Pathology (AMP) guidelines as published by Richards et al 2015.

Will the lab re-contact the ordering physician if variant interpretation changes? Help
Not provided.
Recommended fields not provided:
Clinical validity, Clinical utility, Are family members with defined clinical status recruited to assess significance of VUS without charge?, Will the lab re-contact the ordering physician if variant interpretation changes?, Is research allowed on the sample after clinical testing is complete?, Sample negative report, Sample positive report
Technical Information
Test Procedure: Help
The patient's DNA is sequenced using whole genome sequencing conducted on an Illumina platform at 30X mean mappable coverage. The relevant region(s) of DNA are subsequently isolated in-silico for analysis.
Test Confirmation: Help
Tandem repeat expansions are sent out to a third party CLIA/CAP lab for orthogonal confirmation.
Test Comments: Help
This test includes repeat expansion analysis of 36 loci: AFF2, AR, ARX, ATN1, ATXN1, ATXN2, ATXN3, ATXN7, ATXN8OS, ATXN10, C9ORF72, CACNA1A, CNBP, CSTB, DIP2B, DMPK, FGF14, FMR1, FOXL2, FXN, GIPC1, GLS, HTT, JPH3, LRP12, NOP56, NOTCH2NLC, PABPN1, PHOX2B, PPP2R2B, RFC1, SOX3, TBP, TCF4, VWA1 and ZIC2 genes.

Test performance comments
Specimen preparation and clinical grade sequencing is performed by outside CLIA labs. All data processing, analysis, interpretation, diagnosis and report generation is performed in-house.
Analytical Validity: Help
The Genomic Unity® Exome Plus Analysis is a whole genome sequence based test designed to identify genetic variants that correlate with the patient's clinical symptoms. This test includes sequence analysis (single nucleotide variants, deletions/insertions, characterized intronic and regulatory variants); analysis of copy number variants, duplications/deletions, regions of homozygosity, mobile element … View more
Assay limitations: Help
