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. Contact lab for details

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.

Technical Information
Test Procedure: Help
Next-generation sequencing (NGS) is used to test for the presence of variants within the mitochondrial genome (includes 13 protein coding genes, 22 transfer RNA genes, and 2 ribosomal RNA genes) and to determine the mitochondrial haplogroup of the patient. Large deletions within the mitochondrial genome are first detected by gel … View more
Test Confirmation: Help

Analytical Validity: Help
Analytical sensitivity, specificity, and accuracy are ≥ 99%
Assay limitations: Help
Clinical Correlations: A small percentage of individuals who have mitochondrial genome involvement may have a variant that is not identified by the methods performed. The absence of a variant, therefore, does not eliminate the possibility of a mitochondrial disease due to variant in the mitochondrial genome. Variants in mitochondrial genes … View more

Software used to interpret novel variations Help
Variants may be analyzed using any combination of the following: Alamut, REVEL, Polyphen-2, SIFT, AGVGD, MutationTaster, SpliceSiteFinder-like, MaxEntScan, NNSPLICE, GeneSplicer, gene-specific online databases, ISCA, UCSC Genome Browser

Laboratory's policy on reporting novel variations Help
All novel variants and copy number variants are evaluated for potential pathogenicity and included in the written report, accordingly.
