Abstract: Spike Q677P was detected only once in variant, B.1.1.7, whereas
Q677H was detected in all variants, i.e., B.1.1.7 (n = 1938), B.1.351 (n = 28), P.1 (n = 9), B.1.429 + B.1.427 (n = 132), and B.1.525 (n = 1584).
Abstract: Here, we analyzed the frequency of
Q677P/H and FCS point mutations in 1,144,793 human and 1042 animal
spike protein sequences and from those of the emergent variants B.1.1.7, B.1.351, P.1, B.1.429 + B.1.427, and B.1.525, which were deposited in the database of the GISAID Initiative.
Abstract: Taken together, our results show that
Q677H and FCS point mutations are prevalent and may have various biological effects on the circulating variants.
