The analysis of changes in the structure of the surface protein S (thorn protein) showed that the majority of viruses (63.4%) differed from it by only one amino acid residue.
In the overwhelming majority of cases,mutation D614G, characteristic of the representatives of clade G and its derivatives GH and GR, which have a global distribution. In turn, 33.3% of circulating viruses carry 2–3 substitutions, and only 2.9% have 4 or more substitutions.
