Rare mutations in the accessory proteins ORF6, ORF7b, and ORF10 of the SARS-CoV-2 genomes.
subject: ORF6, pathogenicity, ORF10, ORF7b, Rare mutations
description: A total number of 3080 SARS-CoV-2 genomes from all continents are considered from the NCBI database. Every accessory protein ORF6, ORF7b, and ORF10 of SARS-CoV-2 possess a single missense mutation in less than 1.5% of the 3080 genomes. It has now been observed that different non-synonymous mutations occurred in these three accessory proteins. Most of these rare mutations are changing the amino acids such as hydrophilic to hydrophobic, acidic or basic to hydrophobic, and vice versa etc. So these highly conserved proteins might play an essential role in virus pathogenicity. This study opens a question whether it carries some messages about the virus rapid replications, and virulence.
