Allele Frequency Distribution of SNPs
| SNP | Current data | Previously reported data |
| Total number | 26,530 | 502 |
| Uncommon | 1,342 (5.1%) | 30 (6.0%) |
| Common ≥1 population | 21,101 (79.5%) | 385 (76.7%) |
| Common ≥2 populations | 15,029 (56.6%) | 263 (52.4%) |
| Common in all 3 populations | 7,908 (29.8%) | 135 (27.0%) |
-
A common SNP is defined in which the minor allele frequency is ≥20%. This frequency threshold was used so that the current data could be compared with previously reported estimates of allele frequency (Marth et al. 2001).
