Delta with K417N originally corresponded to lineages AY.1 and AY.2, [50] subsequently also lineage AY.3, [51] and has been nicknamed "Delta plus" or "Nepal variant". [52] It has the K417N mutation, [53] which is also present in the Beta variant. [54] The exchange at position 417 is a lysine-to-asparagine substitution. [55]
The variant, called "Delta with K417N" by Public Health England, includes two clades corresponding to the Pango lineages AY.1 and AY.2. [153] It has been nicknamed "Delta plus" [154] from "Delta plus K417N". [155] The name of the mutation, K417N, refers to an exchange whereby lysine (K) is replaced by asparagine (N) at position 417.
