Allele Frequency Distribution ofSNPs

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).
