Pediatric COVID-19 in Southern California: clinical features and viral genetic diversity
Prof. Xiaowu Gai and Prof. Jennifer Dien Bard from Children’s Hospital Los Angeles (CHLA) recently published a paper exploring clinical features and SARS-CoV-2 genetic variation in children presenting with COVID-19. They observed diverse clinical presentations and identified association between disease severity, viral load and age. By using CleanPlex SARS-CoV-2 Research and Surveillance NGS Panel, they were able to conduct highly sensitive and full-genome interrogation of the SARS-CoV-2 virus using amplicon sequencing on Illumina platforms.
The origin of SARS-CoV-2 in Istanbul: Sequencing findings from the epicenter of the pandemic in Turkey
Prof. Dinler-Doganay’s Lab at Istanbul Technical University, Prof. Doganay and his colleagues at University of Health Sciences, Istanbul, Turkey and Dr. Ilker Karacan from Science and Advanced Technology Research Center, Istanbul, Turkey reported the SARS-CoV-2 viral genomes circulating in Istanbul for the first time. By using Paragon Genomics’ CleanPlex SARS-CoV-2 Research and Surveillance Panel, amplicon-based next-generation sequencing approach was successfully applied to generate near-complete genomes with an average depth of 2616. All three viral genomes carried the D614G variant (G clade according to GISAID classification) with implications for the origin of a spread.
Highly sensitive and full-genome interrogation of SARS-CoV-2 using multiplexed PCR enrichment followed by next-generation sequencing
Prof. Xiaowu Gai and Prof. Jennifer Dien Bard from Children’s Hospital Los Angeles (CHLA), Paragon Genomics R&D teams led by Dr. Zhitong Liu, Prof. Alexander Urban from Stanford University and scientists from MGI / BGI-ShenZhen collaborated on sequencing COVID-19 patient samples using Paragon Genomics’s CleanPlex SARS-CoV-2 Panel for highly sensitive and full-genome interrogation of the SARS-CoV-2 virus using multiplexed PCR enrichment followed by next-generation sequencing.
Molecular assessment of pretransplant chemotherapy in the treatment of leukemia
Prof. Elliot Stieglitz‘s Lab at the UCSF Benioff Children’s Hospital developed a NGS assay powered by Paragon Genomics’ CleanPlex technology to measure the molecular burden of juvenile myelomonocytic leukemia (JMML). The researchers demonstrated that molecular testing can be helpful to distinguish between responders and nonresponders and should become an integral part of clinical care.
Building phylogenomic data sets using highly multiplexed amplicon sequencing
Dr. Scott Geib and fellow researchers at the USDA-Agricultural Research Service developed new approach for building phylogenomic data sets using highly multiplexed amplicon sequencing powered by Paragon Genomics’ CleanPlex technology. The work provided unparalleled resolution of phylogenetic relationships in fruit flies.
Somatic Mutations And T-Cell Clonality In Patients With Immunodeficiency
Dr. Satu Mustjoki and fellow researchers from University of Helsinki, Finland, in collaboration with the University Hospital and Computer Science Department of Aalto University School of Science, report an increase in somatic mutations in CD4+ and CD8+ T cells of patients with immunodeficiency. The team used a custom CleanPlex Panel to validate the low VAF somatic mutations to gain higher confidence in their findings.
Parkin-mediated mitophagy and autophagy flux disruption in cellular models of MERRF syndrome
Prof. José A.Sánchez-Alcázar and fellow researchers from University of Pablo de Olavide, Spain collaborated with researchers from Department of Neurology, Uniklinikum C. G. Carus, Dresden, Germany and Instituto de Salud Carlos III, Spain and used CleanPlex Mitochondrial Disease Panel to study parkin-mediated mitophagy and autophagy flux disruption in cellular models of MERRF syndrome.
Sensitive, highly multiplexed sequencing of microhaplotypes from the Plasmodium falciparum heterozygome
Prof. Bryan Greenhouse, Dr. Sofonias Tessema and fellow researchers from Chan Zuckerberg Biohub, University of San Francisco, USA in collaboration with researchers from University of Massachusetts, Brown University, Clinton Health Access Initiative, and Centro de Investigação em Saúde de Manhiça (CISM) of Mozambique demonstrate that targeted NGS sequencing with a custom CleanPlex Panel can be a flexible tool for efficient, low cost, and high-throughput characterization of polyclonal of P. falciparum infections (Malaria), without the need for WGA.
