Variant Interpretation:
What is the protocol for interpreting a variation as a VUS?
Help
Practice guidelines for the Interpretation and Reporting of Unclassified Variants (UVs) in Clinical Molecular Genetics. Prepared and edited by Jennie Bell, Danielle Bodmer, Erik Sistermans and Simon C Ramsden
Practice guidelines for the Interpretation and Reporting of Unclassified Variants (UVs) in Clinical Molecular Genetics. Prepared and edited by Jennie Bell, Danielle Bodmer, Erik Sistermans and Simon C Ramsden
Are family members with defined clinical status recruited to assess significance of VUS without charge?
Help
No.
No.
Will the lab re-contact the ordering physician if variant interpretation changes?
Help
Yes. We systematically (every 6-8 months) re-evaluated the data and re-contact the physician in case of new findings

Test Procedure:
Help
All coding exons, 50 bp of flanking intronic sequence and at least 100bp of untranslated regions are enriched using Haloplex HS custom targeted protocol (Agilent), followed by high throughput sequencing (Illumina). Sequence variants changes are assessed and interpreted using commercial software combined with public and our own expert database. All …
