The New York State Department of Health's Clinical Laboratory Evaluation Program (CLEP) provides a useful framework for understanding laboratory-developed test oversight, particularly through its guidelines for next-generation sequencing assays. These CLEP requirements for analytical validation are widely recognized as a national standard, yet there is limited peer-reviewed literature detailing the studies needed for CLEP approval. This study presents the validation of the Rapid Pan-Heme (RPPH) assay, a genomic profiling tool for hematopoietic neoplasms, developed in compliance with CLEP standards. The RPPH assay features a comprehensive next-generation sequencing panel targeting &gt;400 genes with clinically relevant variants, including single-nucleotide variants, insertions and deletions, and fusions critical for classifying hematopoietic malignancies. CLEP approval mandates detailed documentation, quality control metrics, validation studies (accuracy, precision, and reproducibility), and compliant clinical reporting. It is demonstrated that RPPH achieves CLEP's stringent analytical sensitivity and reproducibility criteria. Variants were orthogonally validated, and proper controls were implemented. Additionally, it is outlined how RPPH's clinical reports align with CLEP requirements. Overall, this study establishes RPPH as a robust molecular diagnostic tool and provides actionable insights for researchers navigating regulatory compliance and assay validation in clinical settings.</div></div>","PeriodicalId":50128,"journal":{"name":"Journal of Molecular Diagnostics","volume":"27 6","pages":"Pages 485-501"},"PeriodicalIF":3.4,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143755541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optical genome mapping is a high-resolution technology capable of identifying structural variants and copy number variations across the entire genome; however, it currently requires 1 million cells.

First, dilution experiments demonstrated that a 50% CD138-positive mix was sufficient to achieve complete detection of clonal structural and copy number variants, while establishing a detection threshold of 24% for copy number variants. Using this optimized protocol, 13 additional samples from 13 patients were analyzed. Optical genome mapping achieved 93% (13/15) concordance with fluorescence <em>in situ</em> hybridization for clonal anomalies and revealed &gt;22 additional genomic variations not detected by fluorescence <em>in situ</em> hybridization.

Despite their clinical significance, accurate identification and interpretation of CNVs remain challenging, especially in the context of whole-exome sequencing (WES), which is commonly used in clinical diagnostic laboratories. Although WES offers economic advantages over whole-genome sequencing, it struggles with CNV detection because of technical noise introduced by laboratory and analytic processes. Manual curation of CNV calls generated by these tools is labor intensive and error prone. To address this, SeeNV, a command-line tool, is introduced to aid manual curation of CNVs at scale. SeeNV is one solution to these issues, developed in collaboration with and used by the Precision Diagnostics Laboratory at Children's Hospital Colorado. SeeNV generates static infographics for each CNV, incorporating sample and cohort sequencing coverage statistics, CNV population frequency, and, more, facilitating rapid and precise assessment. Using CNV calls identified in publicly available WES and whole-genome sequencing samples, users can rapidly and reliably curate CNV calls, needing only 4.3 seconds to curate a call, achieving 0.95 recall (analytical sensitivity) and 0.74 precision (positive predictive value). SeeNV is freely available for download on GitHub.</div></div>","PeriodicalId":50128,"journal":{"name":"Journal of Molecular Diagnostics","volume":"27 5","pages":"Pages 336-345"},"PeriodicalIF":3.4,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143568766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
