Key: One letter code for corresponding amino acid: A – Alanine, R – Arginine, N – Asparagine, D – Aspartic acid, C – Cysteine, E – Glutamate, Q – Glutamine, G – Glycine, H – Histidine, I – Isoleucine, L – Leucine, K – Lysine, M – Methionine, F – Phenylalanine, P – Proline, S – Serine, T – Threonine, W – Tryptophan, Y – Tyrosine, V – Valine.
The mutation positions are with respect to the reference (hCoV-19/Wuhan/WIV04/2019). The percentage (%) incidence is calculated as number of observed mutations across regions from the total 7213 viral samples. Highly recurrent mutations were observed in nsp12; P4715L, ORF3a; Q57H, N protein; R203K and G204R, and S protein; D614G.
