Discussion: Although more data are needed to elucidate the evolution of SARS-CoV-2 variants in minks, the independent presence of
Y453F in Greek mink farms suggests its positive selection for mink-specific mutations.
Discussion: Most single-nucleotide polymorphisms (SNPs) found within the
S gene were mostly accumulated in the
spike protein RBM region, with the mink-specific amino-acid substitution (
S-
Y453F) being present in all sequenced genomes.
