Trivia:

  • UShER seems to mask spike_339, as you can see multiple branches labeled with S:H339R only when you upload those sequences.
  • This site seems heavily selected for, it is S:G339D(G22578A) introduced since B.1.1.529, then got further mutated into S:G339H(G22577C, G22578A) from BA.2.75 (also on BA.2.86), which got inherited by XBB, and this lineage reverts A22578G to make it S:G339R, if not artifact, that's some 3-step mutations from G to D to H to R.
  • S:G339R only has about 310 seqs on GISAID to date, this lineage represents 20% of them.

@AngieHinrichs: this reversion of 22578 appears real as it clusters extremely well

I was looking at this one for a second time some thoughts:
it is no more a local lineage and have spread in multiple countries
could be S:L335S to enable S:G339R ?
Interesting the trend in positive charge from G to R at 339
