Result: The combination of
G251V and
L37F, which was initially considered a defining mutation pattern for the B.2 to B.6 lineage (clade V in GISAID classification), has shown under more detailed analysis that isolates carrying the
G251V mutation are distributed in other lineages too.
Result: The subsequent amino acid substitutions
L37F in
ORF3a and
G251V in
nsp6 were found to be present in 13.3% and 1.4% of genomes, respectively.
