SARS-CoV-2 strains from 2 Moroccan patients with Covid-19 were sequenced. They belong to clade GK, sublineage AY.33 of Delta variant B1.617.2 (Delta 2). Both samples had T29A, T50I, T299I, and Q613 new amino acid changes, in addition to 10 modifications which characterised it as a Delta variant. The emergence and transmission of novel variations originating from volatile organic compounds (VOCs) is a global issue; their resistance to vaccination is unknown, and genomic surveillance of the SARS-CoV-2 genome remains the key method for detecting variants and preventing their spread.

Phylogenetic analysis of RBD 2019-nCoV spike glycoprotein and SARS-CoV RBD shows relatively high identity of about 73%. (1)According to the findings, several SARS-CoV-specific monoclonal antibodies may be successful at neutralising 2019-nCoV.
(2) It is essential to test anti-SARS-CoV antibodies for cross-reactivity with 2019-nCoV spike protein, since this might have consequences for the fast development of vaccines and therapeutic antibodies against 2019-nCoV.

Korber et al. present evidence that there are now more SARS-CoV-2 viruses circulating in the human population globally that have the G614 form of the Spike protein versus the D614 form that was originally identified from the first human cases in Wuhan, China. Follow-up studies show that patients infected with G614 shed more viral nucleic acid compared with those with D614, and G614-bearing viruses show significantly higher infectious titers in vitro than their D614 counterparts.

Virus mutagenic capability depends upon several factors, including the fdelity of viral enzymes that replicate nucleic acids, as SARS-CoV-2 RNA dependent RNA polymerase (RdRp) According to the observations of the authors, after February 2020, when the first locally transmitted SARS-CoV-2 cases out of Asia were reported, viral genomes presented diferent point mutations, clearly distinguishable within different geographic areas. Over time, it was observed that they were able to identify three recurrent mutations in Europe (in positions 3036, 14408 and 23403) and 3 other different mutations in North America (in positions 17746, 17857 and 18060). So far, these mutations have not been detected in Asia. The number and the occurrence, as well as the median value of virus point mutations registered out of Asia, increase over time. In the preset study, they found that the RdRp mutation, located at position 14408, which is present in European viral genomes starting from February 20th, 2020, is associated with a higher number of point mutations compared to viral genomes from Asia.

Whole Genome sequencing of the WH-Human 1 corona virus (WHCV) was reported The order of genes (5 to 3) was as follows: replicase ORF1ab, spike (S), envelope (E), membrane (M) and nucle- ocapsid (N). WHCV has 5 and 3 terminal sequences that are typical of betacoronaviruses, with 265 nt at the 5 terminal end and 229 nt at the 3 terminal end. The predicted replicase ORF1ab gene of WHCV is 21,291 nt in length and contained 16 predicted non-structural proteins. highly conserved domain (LLRKNGNKG: amino acids 122130) in nsp1 with SARS-CoV. The predicted S, ORF3a, E, M and N genes of WHCV are 3,822, 828, 228, 669 and 1,260 nt in length, respectively.

Sequence analysis of Indian SARS-CoV-2 sequences (3277 from GISAID) revealed that GR, GH, and G (GISAID) or 20B and 20A (Nextstrain) clades were the prevalent clades in India during the middle and later half of the year 2020. SARS-CoV2 sequences from North America, South America, Europe, Africa, Oceania, and Asia (without Indian sequences) were also analyzed to find the clade dynamics. Other than North America and Europe, all the other continents showed the prevalence of GR clade in the middle and later half of the year 2020. North America showed a consistent prevalence of GH clade throughout the year. And a massive increase in GV clade sequences was observed in Europe during the latter part of 2020.

Mutational and Co-mutational analysis of SARS-CoV-2 Sequences from India revealed different Co-mutation patterns and clade-specific mutations across seven Indian states and one union territory during term2 (April 2020 to July 2020) and term3 (August 2020 to December 2020). 70% of sequences from Telangana had 8 and above mutations within a single viral strain. 45% of sequences from Maharashtra possessed 7 co-mutations. West Bengal had a lower number of co-mutations even in ‘Term3’ (nearly 60% of sequences having 2 and 3 co-mutations per viral sequence).

Of 3080 SARS-CoV-2 genomes analyzed, ~1.5% genome had a rare missense mutation in three accessory proteins ORF6, ORF7b, and ORF10. The mutation caused several changes in the R-group properties of amino acids. Of 3080 genomes analyzed, 2126 genomes were from the USA, 306 genomes were from Asia, 281 genomes were from Europe, 365 genomes were from Oceania, and one genome from Africa. Mutations in putative diacidic motif- may affect the suppression of the expression of co-transfected myc-nsp8.
Mutated ORF7b(F(19)L)-Retention in Golgi complex is affected.
Mutated ORF7b (L(20)STOP)-Non-functional protein.
Nonsense mutation in ORF10- Non-functional protein.
Mutated ORF10 (V(6)I)-synonymous change of R-group property (Functions not affected).
Mutation may have potential role in viral rapid replications, virulence and pathogenicity.
