Data are reanalyzed from Rothschild et al. (2024). A total of 185 SNV are observed and this Table contains the 28 SNV conserved in at least 60% of the 30 individuals from the 1,000 genome project (Byrska-Bishop et al., 2022) analyzed by Rothschild et al. (2024). Note that the rDNA numbering in Ref (Rothschild et al., 2024) starts with “0” and is thus shifted by one nucleotide, which is corrected here. If the residue in the chrUN_GL000220v1 reference sequence differs from the reported reference sequence, it is notated in the last column.

ES39B: extension segment 39B; h41: helix 41; j11/12: junction between helices 11 and 12; Ref: Reference; SSU: small (ribosomal) subunit. Residues in bold are not disordered and discussed in the text.
