Variant Interpretation:
What is the protocol for interpreting a variation as a VUS?
Help
Variants are classified using the Standards and guidelines for the interpretation of sequence variants published by the American College of Medical Genetics and Genomics and the Association for Molecular Pathology (Richards et al, 2015, PMID 25741868).
Variants are classified using the Standards and guidelines for the interpretation of sequence variants published by the American College of Medical Genetics and Genomics and the Association for Molecular Pathology (Richards et al, 2015, PMID 25741868).
Are family members with defined clinical status recruited to assess significance of VUS without charge?
Help
Yes. Our VUS resolution program involves targeting additional family members for a VUS, with the intention of this additional information aiding in reclassification of the variant. In order to qualify for our VUS resolution program, your patient must have at least one VUS listed on a test report that was issued … View more

Sequencing: >94% for single nucleotide and >76% for small insertion/deletion variants for the nucleotides evaluated. Exonic deletions/duplications: >97% for unique regions of the genome. This test is not validated to identify small deletions/insertions of greater than 20bp, exonic deletions and duplications in pseudogenes or other repetitive regions of the genome …
