This section contains FAQs that provide information about general dbSNP search options as well as FAQs that cover specific SNP searches — everything from searching for SNPs in populations to searching for SNPs in genes and chromosomes. There are FAQs in this section about searching for SNP primers, and FAQs about searching for a SNP with a specific ID. There are FAQs that show you how to search for specific SNP data, how to conduct Batch queries under various circumstances, and FAQs that show you how to locate SNPs using sequence homology (BLAST). There are even FAQs that show you how to find dbSNP statistical data and data histories or historic data.
