Discussion: The root of the pandemic lies in the parental A lineage with the characteristic C8782T and T28144C mutations.

Discussion: Our results disagreed with who studied the mutations among SARS-CoV-2 collected from various locations and reported C29095T in the N gene, T28144C in the ORF8 gene, and C8782T in the ORF1ab gene as the most frequent mutations.
Comparison of SARS-CoV-2 Evolution in Paediatric Primary Airway Epithelial Cell Cultures Compared with Vero-Derived Cell Lines.
Result: Analysing mutations in the PHE passage series, we identified four changes (C8782T; T18488T; T28144C; A29596G) relative to Wuhan-Hu-1 consistently at ~100% at all passages, likely reflecting fixation in the original virus stock (Figure 2a).

Discussion: In other words, the S variant (Type A) with two mutations at 8782C>T and 28144 T>C was mainly identified in East Asia.
Genomic mutations and changes in protein secondary structure and solvent accessibility of SARS-CoV-2 (COVID-19 virus).
Introduction: Cluster I includes 3037C>T; NSP3:F106F (non-structural protein3:F106F) and 14408C>T; RdRp:P323L, cluster II includes 3037C>T, 14408C>T and 23403A>G; S:D614G, cluster III includes 14408C>T, cluster IV includes 3037C>T, 14408C>T, 23403A>G, 28881G>A; N:R203K, 28882G>A
Genomic Variations in SARS-CoV-2 Genomes From Gujarat: Underlying Role of Variants in Disease Epidemiology.
Result: Clades are characterized as S (C8782T, T28144C, NS8-L84S), L (C241, C3037, A23403, C8782, G11083, G25563, G26144, T28144, G228882), V (NSP6-L37F, NS3-G251V), G (S-D614S), GH (S-D614S, NS3-Q57H), S (S-D614S, NG204R).
Analysis of SARS-CoV-2 mutations in the United States suggests presence of four substrains and novel variants.
Result: In Cluster A, B, C, and D, the co-mutations with the highest number of descendants are [241C>T, 3037C>T, 14408C>T, 23403A>G], [3037C>T, 14408C>T], [8782C>T, 18060C>T, 28144T>C], and [3037C>T, 14408C>T, 23403A>G] respectively.
Result: In contrast, the time evolution plot shows that the ratio of mutatio
Result: Mutation 28144T>C-(L84S), the first known mutation globally, has had a very unsteady trajectory.
