“…Input FASTQ sequence alignment with Wuhan-Hu-1 reference was done using MiniMap2 version 2.22 in CodFreq pipeline (https://github.com/hivdb/codfreq). The output of MiniMap2, an aligned SAM file, was converted to a CodFreq file by a publicly available pipeline using a PySam library (version 0.18.0) and further analyzed with the CoVDB ( 49 , 50 ). PCR and sequencing runs were performed once with the appropriate positive and negative controls.…”

“…Defining of SARS-CoV-2 variant/subvariants and the antiviral resistance mutations that target RdRp and 3CLPro inhibitors were assessed according to the mutation annotations given by CoV-RDB [ 25 ]. In this study, remdesivir (RDV) (Veklury, GS-5734, Gliead Sciences, Inc., Foster City, CA, USA) as RdRp inhibitor, NTV/r (Paxlovid/PF-07321332, Pfizer Labs, New York, NY, USA) and ensitrelvir (ENS) (Xocova/S-217622, Shionogi & Co., Ltd. Osaka, Japan) as 3CLpro inhibitors were assessed.…”

“…The resistance mutations included R285C, A449V, D484Y, V557L, S759A, V792I, E796G, C799F, C799R, E802A, and M924R, that are associated with the reduced activity to RdRp, were matched with GISAID mutations for RDV resistance. For the mutations related to the reduced activity against 3CLpro inhibitors, G15S, T21I, T45I, D48Y, M49I, M49T, L50F, G138S, F140L, N142D, N142L, N142S, G143S, S144A/E/L/P/R/T/V/W, C160F, M165T, E166A/G/K/V, L167F, H172Q/Y/T, H173V, V186G, R188S, Q189K, T190I, A191T/V, Q192A, and Q192E mutation patterns were involved and matched with the GISAID mutations for NTV/r and ENS resistance [ 25 ]. Antiviral drug resistance was interpreted for RdRp and 3CLPro inhibitors as medians ≥10-fold, 5–10-fold, 2.5–5, and <2.5-fold reductions in susceptibility, and gray cell as no susceptibility, according to the CoV-RDB protocols [ 25 ].…”

“…VarEPS [7] assesses the risk level of mutations and variants based on their transmissibility and affinity to neutralizing antibodies. Additionally, databases like CoV-RDB [8, 9] and COG-UK-ME [10] have compiled mutations associated with reduced susceptibility to various factors, such as clinical stage SARS-CoV-2 Spike monoclonal antibody (mAb), RNA-dependent RNA polymerase (RdRP) inhibitor, 3C-like protease (3CLpro) inhibitor, or mutations on T cell epitope. However, despite these significant efforts, there are limitations in terms of efficiency and comprehensiveness.…”
