SARS-CoV-2 sequences from the GISAID Database (deposited from 1 December 2019 to 24 October 2020) were analyzed to identify and characterize the recurrent deletion regions in the SARS-CoV-2 spike protein. Phylogenetic analysis of deletion variants and diverse nondeletion variants were performed to track the specific clades/lineages and transmission pattern of deletion variants.

Sequence alignment of 22164 SARS-CoV-2 genomes from the GISAID database with the reference genome revealed 9210 single nucleotide changes (C>U being the most abundant), resulting in CpG loss. The CpG reduction was linked to two known host molecular defense mechanisms the APOBEC, and ZAP proteins. APOBEC protein catalyze cytosine to uracil (C>U) deamination in ssDNA and ssRNA and ZAP selectively binds to viral CpG regions. High amount of APOBEC and ZAP was found in COVID-19 patients.Selective pressure driving the adaptation of SARS-CoV-2 to its host. Absence of APOBEC enhances zinc-finger antiviral protein (ZAP) activity leading to viral degradation.

Sequence alignment of residues in the 615 to 635 loop and the corresponding NTD binding pocket of representative CoV strains belonging to lineage B of Betacoronavirus. Gaps in the interacting NTD loops and the absence of H146 at the corresponding site on SARS-CoV makes it unlikely that SARS-CoV participates in similar intertrimeric interactions.

Comparative In silico analyses of SARS-CoV-2 genomic features (codon, codon pair, dinucleotide usage, and RNA structure around the frameshift region) was performed to find out the best potential target gene for codon pair deoptimization. Genes N and S are suggested as best targets because of high codon pair bias (CPB) compared to that of other viral genes. 5,064 complete SARS-CoV-2 genomes were analyzed. The codon and codon pair usage was calculated for all the genes coded by SARS-CoV-2. Relative synonymous codon usage (RSCU) and codon pair score (CPS) are the metrics that describe the codon and codon pair usage bias, respectively. The codon pair bias (CPB) is the average CPS across a gene.

The feature of the human-infecting coronavirus (HCoV-229E, HCoV-HKU1, HCoV-NL63, HCoV-OC43, SARS-CoV, MERS-CoV, and SARS-CoV-2), in terms of the CpG composition, have been characterized. The coronaviruses from most of the host species showed CpG suppression in the E ORF, while bat E ORF showed a diverse range from total suppression to overrepresentation, and notably avian coronaviruses and Human SARS-CoV and SARS-CoV-2 showed high CpG ratios in E ORF.
