How do I find SNP allele frequency information for different populations?
You can get SNP allele frequency for different populations by using the genotype report format. To get this format, select a refSNP from a population you are interested in, let’s use rs221 for this example. 1 Go to the Entrez SNP page and type in rs221 in the search text box at the top of the page, and click the “Go” box to generate the rs221 record.2 Click the “Display” drop-down menu toggle located just underneath the tabs on the left near the top of the SNP page, to see a list of SNP display options. Select “genotype detail” as the display type3 If you click on the “+” sign located just to the left of each genotype option, you will see SNP frequency for populations available on dbSNP. You can also get this data in xml format by choosing “genotype XML” as the display type in step 2.
