How do I access allele frequencies in dbSNP?
There are several ways to get allele frequency information: Use the average frequency information for a single reference SNP (refSNP, rs#). The frequency information for a single submitted SNP (ss#), is located toward the bottom of the page. The same data is also available in submission format. To view genotype information for a particular population, do the following: 1 Go to the dbSNP homepage and select the Search by Population detail link and conduct a search as indicated in the documentation.2 Once dbSNP generates a report of the population detail, select a sub-batch ID of interest to generate a Population Detail report.3 To generate an Individual Genotype Batch report, select a batch ID of interest from the Population Detail report.4 To view the individual genotypes of your batch, Select detail located under View genotype in the batch summary section. An example of the Individual Genotype Batch report is available. Allele frequency data are available at dbSNP’s FTP site in severa
