Frequency of N protein key mutations across the SARS-CoV-2 major variants.

The table indicates the frequencies of 16 key mutations described in the SARS-CoV-2 N protein (columns) across the previously Circulating Variants of Concern (Alpha, Beta, Gamma, and Delta), the Current Variants of Concern (Omicron, Omicron - XBB.1.5.X, Omicron – CH.1.1.X, Omicron – BA.2.75.X, Omicron – BA.5, Omicron BQ.1.X, BQ1.1, and XBB.1), the top 5 growing lineages in the world on 2023 February 27th (XBB.1.5, CH.1.1.1, BM.4.1, BM.4.1.1, XBB.1.9) and the top five most counted lineages in Brazil (B.1.617.2, P.1.1, BA.2, AY.43, AY.34.1). Values represent the frequency of each mutation among all reported isolates
