Proposal for a potential BA.2.75*/BQ.1*recombinant sublineage
Earliest sequence: 22.12.2022 (Singapore)
Countries detected: Singapore, Malaysia, USA, England, Austria

This is another potiential BA.2.75*/BQ.1* recombinant sublineage defined by S:D111N, ORF1ab:T1828N, ORF3a:S195P. Nextclade identifies the sequences as XBP or XBS while usher places them within BA.2.75. 42 seq. as of 11.03.23.

Gisaid query: C5748A, T13324C, G21893A, C22747T, T25975C

Defining Mutations:
nuc unique C5748A, T13324C, G21893A, C22747T, T25975C
nuc homoplasies C11124T, C23595T
ORF1ab unique T1828N
ORF1ab homoplasies A3620V
S unique D111N
S homoplasies T678I
ORF3a unique S195P

Small subclade defined by ORF1ab: T749A, P7013L, R7014H, R7014S (11 seq., England) maybe worth proposing on its own.
