The variant allele frequency (VAF), reported as the fraction of sequencing reads supporting a variant call, can be used to screen for technical artifacts, yet a specific filtering threshold has yet to be established. A total of 13,122 manually curated variants, sequenced from 289 patients using the Agilent SureSelect Focused Exome enrichment kit at the University of Kentucky Clinical Genomics laboratory from October 2019 to May 2023, were evaluated. Totals of 278 single-nucleotide polymorphisms (SNPs) and 3340 SNPs as technical artifacts are clinically reported. All reported variants had a VAF between 0.33 and 0.63, and 82% (2725/3340) of sequencing artifacts had a VAF of <0.33. It is proposed that removing SNPs in which the VAF is less than approximately 0.30 reduces manual curation time by approximately 20% while capturing all medically relevant variants in medical exome sequencing data sets.","PeriodicalId":50128,"journal":{"name":"Journal of Molecular Diagnostics","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142479408","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}

A retrospective review of clinical sequencing data for solid tumor malignancies diagnosed between February 2022 and April 2023 on next-generation sequencing data was performed. Cases were reviewed for variants in genes associated with CH/CCUS. Variant allele frequencies and other factors of the sequencing data were assessed for determining risk of CH/CCUS. A total of 2479 cases were evaluated during the study period. Of these, 29 cases demonstrated potential CH/CCUS-associated mutations, with a total of 33 variants identified. These were identified in a variety of tumor types, with gliomas being the most common. Significant cardiac histories were found in over half of cases identified, and few cases had abnormal blood counts. Detailed criteria for flagging variants as suspicious for CH and recommendations for these criteria as future guidelines for reporting are described. These variants are incidental findings that require more extensive follow-up or change in therapy management using a single institutional cohort.","PeriodicalId":50128,"journal":{"name":"Journal of Molecular Diagnostics","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142373414","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}

We developed a single multiplexed PCR and a single-nucleotide extension (SNE) assay to identify 14 common mutations causing 99% of TD I and TD II, including the challenging three adjacent mutations in the stop codon of exon 18 of the FGFR3 gene. The assay design also provides a solution for resolving SNE PCR product sizing using performance optimized polymer-7. The assay was validated using 37 previously characterized, de-identified patient samples representing the nine wild-types and 10 of 14 mutant genotypes. Four artificial templates were synthesized to mimic four TD I mutations not represented in the available patient samples. Fragment size and fluorophore channel for each SNE product from 10 samples and the four artificial templates were used to define bins and panels for analysis with GeneMarker version 3.0 and GeneMapper version 6.0 software. Allele calls (bin placement within the panels) were verified using the remaining 27 previously characterized samples. This TD I and II PCR and SNE assay is a robust multiplexed assay, streamlined, to identify 14 mutations in one single reaction. This assay has a shorter turnaround time in comparison to traditional Sanger or next-generation sequencing.","PeriodicalId":50128,"journal":{"name":"Journal of Molecular Diagnostics","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142367258","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}

Consequently, most children born to T. cruzi-infected mothers are required to undergo serological testing after 9 months, which risks loss to follow-up. Alternatively, the loop-mediated isothermal amplification (LAMP) test for T. cruzi DNA offers high analytical and clinical performance and is easy to use in low-complexity laboratories. Recently, we optimized this technique using an ultrarapid DNA extraction method combined with the LAMP in dried blood spots (DBSs) on FTA cards. The procedure has been implemented in 10 public maternities across Paraguay, Bolivia, and Argentina, involving the training of 14 technicians. Operators' performance was evaluated using a standardized DBS testing panel for harmonization, including negative controls and DBS samples artificially contaminated with T. cruzi at 50 and 20 cells/mL. There was strong agreement (ĸ = 0.924) for controls and 50 cells/mL samples, and good agreement (ĸ = 0.718) across all testing panels, even at the detection limit of the test. A prospective study collected 306 DBSs from 222 newborns at birth and/or 2 months, detecting T. cruzi microscopically in four cases. LAMP identified eight positive cases and perfectly aligned with real-time PCR (ĸ = 1), demonstrating higher sensitivity than microscopic observation for early detection of infection in infants.","PeriodicalId":50128,"journal":{"name":"Journal of Molecular Diagnostics","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142367259","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}

However, methodology for the targeted detection of these SVs is lacking. This article reports the use of formalin-fixed paraffin-embedded targeted-locus capture (FFPE-TLC) sequencing as a novel technology for the targeted detection of tumor-specific SVs. Analysis of 29 FFPE colorectal tumor samples and 8 matched normal samples revealed tumor-specific SVs in 24 patients (83%), with a median of 2 SVs per patient (range, 1 to 21). A total of 104 SVs were found in the common fragile site-associated genes MACROD2, PRKN, FHIT, and WWOX in 18 patients (62%), and 39 SVs caused by three LINE transposable elements were found in 15 patients (52%). Tumor specificity of SVs was independently verified by Droplet Digital PCR of tumor tissue DNA, and their applicability as plasma circulating tumor DNA biomarkers was demonstrated. It was concluded that FFPE-TLC sequencing enables the detection of tumor-specific SVs caused by chromosomal rearrangements and LINE retrotranspositions in FFPE tissue. Therefore, FFPE-TLC sequencing facilitates the investigation of the biological and clinical effects of SVs using FFPE material from (retrospective) cohorts of cancer patients and has potential clinical applicability in the detection of SV biomarkers in the routine molecular diagnostics setting.","PeriodicalId":50128,"journal":{"name":"Journal of Molecular Diagnostics","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142331459","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}
