Abstract

The rapid emergence of SARS-CoV-2 variants raised public health questions concerning the capability of diagnostic tests to detect new strains, the efficacy of vaccines, and how to map the geographical distribution of variants to understand transmission patterns and loads on healthcare resources. Next-generation sequencing (NGS) is the primary method for detecting and tracing new variants, but it is expensive, and it can take weeks before sequence data are available in public repositories.

    Pairwise whole-genome alignments of all sequences were performed using LASTZ v1.04.02 with NCBI Reference Sequence: NC_045512.2 as the SARS-CoV-2 reference genome.20,21 The Bioconductor package for genetic variants, VariantAnnotation v1.20.2, was then used for the translation into amino acids in R v3.3.2, and the identification of amino acid substitutions or frameshifts were used to call a unique mutation incident.22,23 Selection of the lineages considered for the marker panel was performed by combining the top 100 most frequent lineages reported worldwide for the 120-day period between May 12, 2021 and September 11, 2021 (data not shown). 1,200,791 sequences representing 393 lineages were analyzed.

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding. For details on the theoretical underpinning of rigor criteria and the tools shown here, including references cited, please follow this link.
