Elucidation of Genome Polymorphisms in Emerging SARS-CoV-2

The COVID-19 pandemic is having a devastating effect on the healthcare system and the economy of the world. The unavailability of a specific treatment regime and a candidate vaccine yet opens up scope for new approaches and discoveries of drugs for mitigation of the sufferings of humankind due to the disease. The present isolated whole-genome sequences of SARS-CoV-2 from 11 different nations subjected to evolutionary study and genome-wide association study throughin silicoapproaches including multiple sequence alignment, phylogenetic study through MEGA7 and have been analyzed through DNAsp respectively. These investigations recognized the nucleotide varieties and single nucleotide mutations/polymorphisms on the genomic regions as well as protein-coding regions. The resulted mutations have diversified the genomic contents of SARS-CoV-2 according to the altered nucleotides found in 11 genome sequences. India and Nepal have found to have progressively more distinct species of SARS-CoV-2 with variations in Spike protein and Nucleocapsid protein-coding sites. These genomic variations might be the explanation behind the less case fatality rate of India and Nepal dependent on the populaces. The anticipated idea of this investigation upgrades the information about genomic medication and might be useful in the planning of antibodies against SARS-CoV-2.
