ROCKVILLE, Md. – May 18, 2023 – The Association for Molecular Pathology (AMP), the premier global molecular diagnostic professional society, has published a report that was designed to establish recommendations for standardizing orthogonal confirmation practices for germline variants detected by next-generation sequencing (NGS). The manuscript, “ Recommendations for Next-Generation Sequencing Germline Variant Confirmation: A Joint Report of the Association for Molecular Pathology and National Society of Genetic Counselors ,” was released online ahead of publication in The Journal of Molecular Diagnostics .
“While NGS has quickly transformed the field of clinical molecular genetic testing, orthogonal confirmation practices for germline variants may vary between laboratories,” said Kristy R. Crooks, PhD, Associate Professor and Laboratory Director at the University of Colorado Anschutz Medical Campus, and Chair of the AMP NGS Germline Variant Confirmation Working Group. “This new report provides recommendations for orthogonal confirmation practices that, in concert with existing guidelines, are designed to help promote standardization, transparency, and quality improvement among laboratories.”
The AMP Clinical Practice Committee convened the NGS Germline Variant Confirmation Working Group to assess current evidence and standardize orthogonal confirmation practices to help limit the reporting of false positives. The new report offers the following eight recommendations that are based on a comprehensive review of published literature, empirical data, current laboratory practice surveys, feedback from open public comment, and professional experiences.
“This new report was meant to summarize the current collective state of knowledge and guide clinical laboratory professionals regarding orthogonal confirmation of germline variants,” said Susan Hsiao, MD, PhD, Associate Professor of Pathology and Cell Biology at Columbia University Vagelos College of Physicians and Surgeons, and 2023 AMP Clinical Practice Committee Chair. “AMP will continue to reassess and modify our guidelines as the methodology and bioinformatics underlying NGS-based variant detection develop as part of our ongoing commitment to improving clinical practice and patient care.”
