BACKGROUND Current estimates suggest that even in the most resourced settings, the aetiology of encephalitis is identified in less than half of clinical cases. It is acknowledged that filling this gap needs a combination of rigorous sampling and improved diagnostic technologies. Next generation sequencing (NGS) methods are powerful tools with the potential for comprehensive and unbiased detecti...

Next-generation sequencing (NGS) is becoming a standard for genetic analyses of clinical samples. DNAs retrieved from formalin-fixed, paraffin-embedded (FFPE) tissue specimens are commonly degraded, and specimens such as core biopsies are sometimes too small to obtain enough DNA for NGS applications. Thus, it is important to measure both the DNA quantity and quality accurately from clinical sam...

Diagnostic Yield of Clinical Next-Generation Sequencing Panels for Epilepsy During the past 2 years, next-generation DNA sequencing (NGS) has become a widespread diagnostic tool in neurology. Several studies have addressed the diagnostic yield and cost of NGS relative to other types of DNA testing. G-banded karyotyping identifies chromosomal aberrations and has a 3% diagnostic yield for unexpla...

To investigate the causative agent of swine diarrhea, next-generation sequencing (NGS) was performed on a porcine fecal sample. The NGS reads were assembled, which generated a complete swine Deltacoronavirus genome sequence, that of strain SDCV/USA/Illinois121/2014.

In this issue of Neurology® Neuroimmunology & Neuroinflammation, Salzberg et al report on the results of a small prospective study of the application of nextgeneration sequencing (NGS) of RNA and DNA extracted from brain biopsy tissue specimens obtained from 10 patients with suspected neuroinfectious disease processes. In 3 patients, the NGS results, which included JC virus, Epstein-Barr virus,...

Next-generation sequencing (NGS) is not routinely used in applied settings due to lack of confidence in results. This workshop convened experts to identify measurement challenges impeding NGS implementation and potential standards-based solutions to address these challenges.
