Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
All detected variants are evaluated according to the most recent American College of Medical Genetics and Genomics (ACMG) and Association for Molecular Pathology (AMP) recommendations. Variants are classified based on known, predicted, or possible pathogenicity and reported with interpretive comments detailing their potential or known significance.

Are family members with defined clinical status recruited to assess significance of VUS without charge? Help
Decline to answer.

Will the lab re-contact the ordering physician if variant interpretation changes? Help
No. The laboratory encourages health care providers to contact the laboratory at any time to learn how the status of a particular variant may have changed over time.
Research:
Is research allowed on the sample after clinical testing is complete? Help
Research testing is only performed under IRB approved protocol with an opt-out policy in place.
Recommended fields not provided:
Clinical validity, Clinical utility, Sample negative report, Sample positive report
Technical Information
Test Procedure: Help
This test utilizes next-generation sequencing to detect single nucleotide and copy number variants in 221 nuclear genes and amplification of the entire mitochondrial genome by long-range polymerase chain reaction.
Test Confirmation: Help
Confirmation of select reportable variants will be performed by alternate methodologies based on internal laboratory criteria.
Availability: Help
Tests performed
Entire test performed in-house
Analytical Validity: Help
Next-generation sequencing (NGS) and/or Sanger sequencing is performed to test for the presence of variants in coding regions and intron/exon boundaries of the genes analyzed, as well as some other regions that have known disease-causing variants. The human genome reference GRCh37/hg19 build was used for sequence read alignment. At least … View more
