Table 2.
Synonymous versus Nonsynonymous Substitutions in wzd and wze.
| Dataset | N in wzd/wze | S in wzd/wze | N in Other | S in Other | P value |
|---|---|---|---|---|---|
| PMEN1 | 21 | 1 | 39 | 15 | 0.03 |
| PMEN2 | 9 | 1 | 19 | 6 | 0.64 |
| PMEN14 | 37 | 1 | 7 | 3 | 0.03 |
| Total | 67 | 3 | 65 | 24 | 10−4 |
Note.—The table shows the number of synonymous (S) and nonsynonymous (N) substitutions in wzd and wze versus other genes in the cps locus in three PMEN lineages. P value shows the significance of the Fisher’s exact test examining the proportion of nonsynonymous to synonymous mutations in the wzd/wze region.
