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

Analytical Validity: Help
IriSight™ for Pregnancy Loss is a whole genome sequence based test designed to identify genetic variants that correlate with pregnancy loss, prenatal findings and/or are predicted to result in severe, early onset genetic disorders. This test includes sequence analysis (single nucleotide variants, deletions/insertions, characterized intronic variants); copy number variants, duplications/deletions, … View more
