Recombination: Details on XD, XE and XF recombinants by Tom Peacock
There’s a new thread on Twitter by Tom Peacock of Imperial College covering the latest information on the SARS-CoV-2 recombinants XD, XE and XF.
XD is the new name for the French Delta x BA.1 lineage.
XE is a large UK BA.1 x BA.2 lineage. Sequenced and verified by @UKHSA and @sangerinstitute, first identified by @nzm8qs
XF is a UK Delta x BA.1 lineage. Again sequenced and verified by @UKHSA and first identified by @nzm8qs
Thread starts below:
With three Omicron-related recombinants getting assigned Pango lineages I'm going to write a thread covering:
– What are recombinants?
– Why are we seeing so many now?
– What exactly are the new lineages XD, XE and XF?
– How concerned should we be about them? pic.twitter.com/PrPGaUSs3p

** Were they named XD, XE and XF for Scrabble purposes? **
