Application of a Sanger-Based External Quality Assurance Strategy for the Transition of HIV-1 Drug Resistance Assays to Next Generation Sequencing

The Nationwide Institute of Allergy and Infectious Ailments (NIAID) Virology High quality Assurance (VQA) established a sturdy proficiency testing program for Sanger sequencing (SS)-based HIV-1 drug resistance (HIVDR) testing in 2001. Whereas most of the classes discovered through the growth of such applications may additionally apply to subsequent technology sequencing (NGS)-based HIVDR assays, challenges stay for the continued analysis of NGS-based testing. These challenges embrace a correct evaluation of assay accuracy and the reproducibility of low abundance variant detection, intra- and inter-assay efficiency comparisons amongst laboratories utilizing lab-defined assessments, and totally different knowledge evaluation pipelines designed for NGS. In collaboration with the World Well being Group (WHO) International HIVDR Laboratory Community and the Public Well being Company of Canada, the Rush VQA program distributed archived proficiency testing panels to 10 laboratories to guage internally developed NGS assays.
Consensus FASTA information have been submitted utilizing 5%, 10%, and 20% variant detection thresholds, and scored based mostly on the identical standards used for SS. This small research confirmed that the SS Exterior High quality Assurance (EQA) strategy can be utilized as a transitional technique for utilizing NGS to generate SS-like knowledge and for ongoing efficiency whereas utilizing NGS knowledge from the identical high quality management supplies to additional consider NGS assay efficiency. Lung most cancers (LC) is the primary reason behind demise for most cancers worldwide and non-small cell lung most cancers (NSCLC) represents the commonest histology.
The invention of genomic alterations in driver genes that supply the opportunity of therapeutic intervention has fully modified the strategy to the analysis and remedy of superior NSCLC sufferers, and tumor molecular profiling has grow to be necessary for the selection of probably the most acceptable therapeutic technique. Nevertheless, in roughly 30% of NSCLC sufferers tumor tissue is insufficient for biomarker evaluation. The event of extremely delicate subsequent technology sequencing (NGS) applied sciences for the evaluation of circulating cell-free DNA (cfDNA) is rising as a invaluable different to evaluate tumor molecular panorama in case of tissue unavailability. Moreover, cfDNA NGS testing can higher recapitulate NSCLC heterogeneity as in contrast with tissue testing. On this overview we describe the primary benefits and limits of utilizing NGS-based cfDNA evaluation to information the therapeutic decision-making course of in superior NSCLC sufferers, to watch the response to remedy and to establish mechanisms of resistance early.

 

 

Fast EGFR Mutation Detection Utilizing the Idylla Platform: Single establishment expertise of 1200 instances analyzed by an in-house developed pipeline and comparability with concurrent subsequenttechnology sequencing outcomes

Mutations within the epidermal development issue receptor (EGFR) are the commonest targetable alterations in lung adenocarcinoma. To facilitate speedy testing, we integrated the Idylla EGFR assay as screening technique previous to subsequent technology sequencing (NGS). We describe our validation and expertise utilizing an in-house developed evaluation pipeline, enhanced with a guide overview algorithm. Outcomes are in contrast with corresponding NGS outcomes. In all, 1,249 samples have been studied. Validation demonstrated 98.57%  concordance with the reference strategies. The restrict of detection diverse from 2 to five% variant allele frequency if whole EGFR Cq was between 20 and 23. Of 1179 scientific instances, 23.41% have been EGFR constructive by Idylla.
Concurrent NGS was efficiently carried out on 94.9%  of requests. Concordance of Idylla with NGS was 98.62% and 98.50%  utilizing our in-house and Idylla evaluation pipelines, respectively. Discordances concerned missed mutations by each assays related to low tumor/low enter. Incorporating a guide overview algorithm to complement automated calls, improved accuracy from 98.62 to 99.37% and sensitivity from 94.68% to 97.58%. Total reporting time, from receipt of fabric to official scientific report, ranged from 1-Three days. We conclude that Idylla EGFR testing permits speedy and delicate screening with out compromising subsequent complete NGS, when required. Subsequent-generation sequencing (NGS) is more and more being adopted as a invaluable technique for the detection of somatic variants in scientific oncology.
Nevertheless, it’s nonetheless difficult to succeed in a passable degree of robustness and standardization in scientific follow when utilizing the at the moment obtainable bioinformatics pipelines to detect variants from uncooked sequencing knowledge. Furthermore, acceptable reference datasets are missing for scientific bioinformatics pipeline growth, validation and proficiency testing. Right here, we developed VarBen, an open-source software program for variant simulation to generate custom-made reference datasets by straight enhancing the unique sequencing reads. VarBen can introduce quite a lot of variants, together with single-nucleotide variants, small insertions and deletions, and enormous structural variants, into focused, exome or whole-genome sequencing knowledge, and might deal with sequencing knowledge from each the Illumina and Ion Torrent sequencing platforms.

Analysis of Ion Torrent subsequenttechnology sequencing for thalassemia analysis

Introduction: To guage a next-generation sequencing (NGS) workflow within the screening and analysis of thalassemia.
StrategiesOn this potential research, blood samples have been obtained from folks present process genetic screening for thalassemia at our centre in Guangzhou, China. Genomic DNA was polymerase chain response (PCR)-amplified and sequenced utilizing the Ion Torrent system and outcomes in contrast with conventional genetic analyses.
OutcomesOf the 359 topics, 148 (41%) have been confirmed to have thalassemia. Variant detection recognized 35 differing types together with the commonest. Identification of the mutational websites by NGS have been in keeping with these recognized by Sanger sequencing and Hole-PCR. The sensitivity and specificities of the Ion Torrent NGS have been 100%. In a separate take a look at of 16 samples, outcomes have been constant when repeated ten instances.
