Result: We also analyzed the effect of 27 missense variants of SARS-CoV-2
spike protein (
RBD) on the binding interaction of
spike protein with ACE2 and observed that

Abstract: The comprehensive escape mutation map not only confirms the widely circulating strains carrying important immune escape
RBD mutations such as
K417N,
E484K, and
L452R, but also facilitates the discovery of new immune escape-enabling mutations such as
F486L,
N450K,
F490S, and
R346S.
Result: Markedly,
K417N,
F486L,
L452R,
E484K, and
R346S resulted in resistance to at least six plasma samples, as the NAb titers were approximately 2-4 times lower than those for the wildtype, indicating that NAbs targeting these key residues were e
