D399N in the context of other N gene mutations in deposited GISAID consensus sequences. Matrix shows co-occurrences of D399N with other N gene mutations, sorted in descending frequency from left to right, with frequencies plotted above as a bar plot. Frequency of each individual mutation is plotted to the left. Highlighted in orange are the genomes with D399N without any co-occurring N gene mutations. N gene mutations with <10 total co-occurrences are collapsed into an “Other N mutations” category.
