Description

Next-generation sequencing (NGS) stands as a transformative technology, continually redefining diagnostics and fundamental biological research. It has significantly advanced, enhancing the ability to identify subtle genetic variations critical for diagnosing a spectrum of genetic conditions. Its expanding role in clinical settings underscores both its present utility and substantial future possibilities in patient care [1]. In cancer research, NGS offers an updated view, thoroughly detailing genomic applications like precise mutation identification and delving into epigenomic uses, such as methylation profiling. This comprehensive approach provides a deeper molecular understanding of cancer's intricacies, aiding in better diagnostic and therapeutic strategies [2].

Specialized applications of NGS address unique biological challenges. Single-cell NGS (scNGS), for example, is highlighted for its diverse methods and broad applications across various biological research areas, emphasizing its unparalleled power to analyze individual cells. This capacity allows for granular insights not achievable with bulk sequencing [3]. Furthermore, long-read sequencing technologies, a distinct form of NGS, are reviewed for their current status and challenges. These technologies, exemplified by platforms like PacBio and Oxford Nanopore, offer advantages in resolving complex genomic regions, providing crucial information often missed by shorter reads, although ongoing efforts are needed to refine data analysis and accuracy [5].

The clinical relevance of NGS is profound, particularly in infectious disease management and broader clinical genomics. NGS is increasingly important for diagnosing infectious diseases, encompassing methods and clear benefits for rapid pathogen identification, precise strain typing, and efficient resistance gene detection. This makes it an indispensable tool in modern clinical microbiology [4]. The application extends to clinical genomics, where various NGS technologies are explored for their specific uses in diagnostic settings. This includes the accurate detection of inherited diseases and its significant contribution to pharmacogenomics, tailoring medical approaches to individual genetic makeup [6].

Pharmacogenomics benefits immensely from NGS, which facilitates the identification of genetic variations directly influencing drug response. While this is a critical step towards personalized medicine, the field still grapples with challenges in translating complex sequencing data into practical clinical guidance [7]. In parallel, RNA sequencing (RNA-Seq) technologies, a key application under the NGS umbrella, have seen substantial progress. These advancements offer diverse methodologies and applications, from comprehensive gene expression profiling to the discovery of novel transcripts, significantly deepening our understanding of dynamic transcriptomes and their roles in health and disease [8].

NGS has also driven significant advancements in metagenomics, enabling comprehensive analysis of microbial communities within diverse environments. This involves various sequencing strategies, though the field continues to tackle computational and biological hurdles to refine its utility further [9]. Ultimately, integrating NGS into precision medicine holds immense promise. It explores how NGS can personalize treatments by identifying individual genetic variations, yet this pathway is not without obstacles. Challenges in data interpretation, successful clinical implementation, and critical ethical considerations must be carefully navigated to fully realize the potential of NGS in transforming personalized healthcare [10].

Conclusion

Next-generation sequencing (NGS) has rapidly evolved, becoming indispensable across numerous biological and clinical fields. Its applications span the accurate diagnosis of genetic conditions, where it excels at spotting subtle variations and plays an expanding role in clinical settings. NGS is also critical in cancer research, revealing genomic and epigenomic insights like mutations and methylation profiles for a deeper molecular understanding. In clinical microbiology, it's vital for identifying infectious pathogens, typing strains, and detecting resistance genes, significantly improving diagnostics. Beyond diagnostics, NGS encompasses specialized techniques such as single-cell sequencing, which provides granular insights into individual cells, and long-read sequencing, valuable for resolving complex genomic regions despite analytical challenges. The technology is fundamental in clinical genomics, aiding in inherited disease detection and pharmacogenomics by identifying genetic variations influencing drug responses, thereby supporting personalized medicine. Further extending its reach, RNA sequencing advances our understanding of transcriptomes through gene expression profiling, while metagenomics uses NGS for comprehensive microbial community analysis. However, integrating NGS into precision medicine, though promising for personalized treatments, faces ongoing hurdles in data interpretation, clinical implementation, and ethical considerations. Overall, NGS continues to drive significant progress, navigating challenges to deliver increasingly precise and comprehensive genomic insights.
