next generation sequencing principle

It enables scientists to analyze the entire human genome in a single sequencing experiment, or sequence thousands to tens of thousands of genomes in one year. A, illustration of well-documented translocation between chromosomes 17 and 22 which places the platelet-derived growth factor-β (PDGFB) gene under control of the highly active collagen type 1A1 promoter (COL1A1). Sunyaev S, Ramensky V, Koch I, Lathe 3rd W, Kondrashov AS, Bork P. Prediction of deleterious human alleles. Biomark Med. 2012;14:467–75. In targeted NGS reactions, sequencing reads are intentionally distributed to specific genomic locations, which allows for higher sequencing coverage and therefore ensures accurate detection of sequence variants at these loci, regardless of platform error rates. Nucleic Acids Res. The DNA polymerase then binds to the primer and adds the first fluorescently-labelled terminator to the new DNA strand. Accurate and comprehensive sequencing of personal genomes. Wang K, Li M, Hakonarson H. ANNOVAR: functional annotation of genetic variants from high-throughput sequencing data. So-called “next-generation” sequencing technologies enable rapid generation of data by sequencing massive amounts of DNA in parallel using diverse methodologies which overcome the limitations of Sanger sequencing methods used to sequence the first human genome. We provide an overview of the capabilities and clinical applications of DNA sequencing technologies to raise awareness among researchers about the power of these novel genomic tools. Nat Genet. Hugo J. Investment in the development of NGS technologies by the NHGRI was made with the goal of expediting the use of genome sequencing data in the clinical practice of medicine. Inherent to NGS technologies are unique sequencing chemistries that differ from the Sanger dideoxynucleotide chain termination chemistry. 2008;36, e105. Field guide to next-generation DNA sequencers. Voelkerding KV, Dames SA, Durtschi JD. Next Generation Sequencing (NGS) Die Einführung der Next Generation Sequencing (NGS)-Technologien hat die Etablierung bedeutender, neuer diagnostischer Anwendungen in der täglichen Routine ermöglicht. Nat Methods. Kirkness EF. For example, a population-scale sequencing effort known as the 1,000 Genomes project is collecting WGS data from a diverse sampling of individuals to map patterns of inheritance, typically focusing on the most common form of genetic variation, the SNP (41, 59). Next Generation Sequencing (NGS) and Sanger Sequencing are two types of nucleotide sequencing techniques developed over the time. Ironically, one of the key limitations of NGS also serves as its greatest strength, the high volume of data generation. In principle, the concept behind NGS technology is similar to CE—the bases of a small fragment of DNA are sequentially identified from signals emitted as each fragment is … Analysis of large sequencing data sets mandates an advanced computational infrastructure dedicated to preserving, processing, and analyzing NGS data. Direct selection of human genomic loci by microarray hybridization. 29), regulatory regions (FAIRE-Seq and DNase-Seq; refs. 1 Definition. Next-generation sequencing, in contrast, makes large-scale whole-genome sequencing (WGS) accessible and practical for the average researcher. 2C and D). Application of next generation sequencing to molecular diagnosis of inherited diseases. Rapid, low-input, low-bias construction of shotgun fragment libraries by high-density in vitro transposition. Genome Res. Summerer D, Wu H, Haase B, Cheng Y, Schracke N, Stahler CF, Chee MS, Stahler PF, Beier M. Microarray-based multicycle-enrichment of genomic subsets for targeted next-generation sequencing. Zhang W, Cui H, Wong LJ. Unlocking Mendelian disease using exome sequencing. Ding and colleagues also used NGS to sequence cancer genomes from metastasis and primary breast cancer samples to investigate the mutational evolution of cancer cells, identifying two de novo mutations and a large deletion acquired by metastatic cells during disease progression and 20 mutations shared by primary and metastatic cell populations (58). 2009;27:1025–31. © 2020 Springer Nature Switzerland AG. A basic workflow for NGS sequencing technologies is presented in Fig. MacArthur DG, Balasubramanian S, Frankish A, Huang N, Morris J, Walter K, Jostins L, Habegger L, Pickrell JK, Montgomery SB, Albers CA, Zhang ZD, Conrad DF, Lunter G, Zheng H, Ayub Q, DePristo MA, Banks E, Hu M, Handsaker RE, Rosenfeld JA, Fromer M, Jin M, Mu XJ, Khurana E, Ye K, Kay M, Saunders GI, Suner MM, Hunt T, Barnes IH, Amid C, Carvalho-Silva DR, Bignell AH, Snow C, Yngvadottir B, Bumpstead S, Cooper DN, Xue Y, Romero IG, Wang J, Li Y, Gibbs RA, McCarroll SA, Dermitzakis ET, Pritchard JK, Barrett JC, Harrow J, Hurles ME, Gerstein MB, Tyler-Smith C. A systematic survey of loss-of-function variants in human protein-coding genes. Amplification-based and single-molecule sequencing technologies have been referred to as “second-generation” and “third-generation” sequencing technologies, respectively, in the literature (ref. Quality scores and SNP detection in sequencing-by-synthesis systems. Demand for fast, inexpensive, and accurate DNA sequencing data has led to the birth and dominance of a new generation of sequencing technologies. For example, local sequence content has been shown to exert a bias on the coverage of short read NGS platforms, whereby higher read densities are more likely to be found at genomic regions with elevated GC content (37). Conceptually, an NGS instrument can be thought of as a digital measuring stick for genome cartography efforts, providing information on the nucleotide content, relative abundance, and genomic locations of the DNA templates and its sequences. Sanger sequencing (chain termination methodology), created during the mid-1970’s by Frederick Sanger and co-workers has been the molecular biology workhorse for many years. 6 (June 2016): 333–51. De Keulenaer S, Hellemans J, Lefever S, Renard JP, De Schrijver J, Van de Voorde H, Tabatabaiefar MA, Van Nieuwerburgh F, Flamez D, Pattyn F, Scharlaken B, Deforce D, Bekaert S, Van Criekinge W, Vandesompele J, Van Camp G, Coucke P. Molecular diagnostics for congenital hearing loss including 15 deafness genes using a next generation sequencing platform. These input metrics are typically easy to achieve using unmodified fresh or fresh-frozen samples, however, this may be more challenging with clinical specimens, especially archived formalin-fixed, paraffin-embedded (FFPE) samples. Anal Bioanal Chem. dsDNA, double-stranded DNA; TFBS, transcription factor–binding sites. Nature. Cluster Generation Sequencing Illumina Sequencing Workflow. NGS platforms perform massively parallel sequencing, during which millions of fragments of DNA from a single sample are sequenced in unison. The main limitation of Sanger sequencing is one of throughput, that is, the amount of DNA sequence that can be read with each sequencing reaction. Current clinical testing applications including multigene panels and exome and genome sequencing for candidate and causal gene identification are discussed. Biesecker LG. Interestingly, oncogenic mutations in ARID1A and DICER1 genes were again shown to be reproducibly identified in other samples with high specificity by alternative means. Accurate whole human genome sequencing using reversible terminator chemistry. Cancer Prevention Research Next-generation sequencing (NGS) is not a single technology, but rather several different technologies that share a common feature of massively parallel sequencing of clonally amplified or single DNA molecules in a flow cell or chip. Success stories from early clinical pilot studies using NGS underscore the value of using a mutidisciplinary team dedicated to the collection and interpretation of NGS data in a clinically relevant time frame (55, 56).
