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.

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
Decline to answer.
Recommended fields not provided:
Clinical validity, Clinical utility, Is research allowed on the sample after clinical testing is complete?, Sample negative report, Sample positive report
Technical Information
Test Procedure: Help
Whole genome sequencing is conducted on an Illumina platform using the Illumina TruSeq DNA PCR-Free Library Preparation Kit at 30X mean mappable coverage. Analysis is focused on the muscular dystrophy associated genes listed at https://www.variantyx.com/md-analysis/

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® Muscular Dystrophy Analysis is designed to identify genetic variants that correlate with muscular dystrophies. This analysis includes sequence analysis (single nucleotide variants, deletions/insertions, and characterized intronic variants), copy number variants, duplications/deletions, mobile element insertions, and inversions in a panel of 52 genes. The sensitivity, specificity and positive … View more
