Table 1A. Summary of most common amino acid variants in found Spike. All sites that vary in >0.3% of our global Spike sequence alignment are listed, and if they are in the ACE2 contact region, the threshold for inclusion is dropped to >0.1%.
Table 1B. Details concerning these most common mutations in Spike, including covarying common variants, the codon change leading to the amino acid change, and counts of variants including the geographic origin of the variants.
Table 2. All positions in Spike are listed, with the frequencies of variant forms in position, the entropy of each position, and the local regional entropy of spanning 10 continuous amino acid segments, to highlight nearby regions of variation.
