An insertion unique to SARS-CoV-2 exhibits superantigenic character strengthened by recent mutations.
Method: Two mutants associated with European Covid-19 patients were constructed using CHARMM-GUI: one is the main strain mutant D614G and the other contains four mutations including Q239K, A831V, D614G and D839Y.
SARS-CoV-2 gene content and COVID-19 mutation impact by comparing 44 Sarbecovirus genomes.
Result: First, we investigated Sarbecovirus conservation of 14 amino acids in the spike protein in which mutations appear to be accumulating in the SARS-CoV-2 population, namely D614G, L5F, L8V/W, H49Y, Y145H, Q239K, V367F, G476S, V483A, V615I/F, A831V, D839Y/N/E, S943P, P1263L.
Result: In contrast, L5F, L8V/W, H49Y, PMID: 32730807

Result: Although the eight single mutations (i.e., Q239K, V341I, A435S, K458R, I472V, H519P, A831V, and S943T) in both groups A and B do not exist by themselves, they were found to occur in combination with D614G.

Superantigenic character of an insert unique to SARS-CoV-2 spike supported by skewed TCR repertoire in patients with hyperinflammation.
Method: Two mutants associated with European COVID-19 patients were constructed using CHARMM-GUI: one is the main strain mutant D614G, and the other contains four mutations including Q239K, A831V, D614G, and D839Y.
