Result: An additional aa change was also present in S2 subunit HRP2 region (V1176F) of MT21774/2020 (Figure 3C).
Discussion: The V1176F aa change (MT21774 sequence) is located in the short S2 subunit, region involved in viral envelope fusion with cell membrane after ACE2-receptor binding, TMRPSS2 priming and endocytosis.

Figure: L18F, E484K, N501Y, D614G, H655Y, and V1176F are associated with the Gamma variant of concern, and S13I, W152C, L452R are associated with the Epsilon variant of concern.
Discussion: The spike protein mutation V1176F results in increased stability of the spike protein and has also been associated with higher mortality rates.

Result: The amino acid substitutions detected in both the isolates were D614G, E484K, V1176F in the spike, A119S, G204R, M234I, R203K in the N, L205V in NSP5, L71F in NSP7 and P32L in NSP 12.
Discussion: The characteristic spike mutations in P2 lineage are D614G, E484K and V1176F.
