Detailed information page for an individual SNP. The page is divided into five sections. The first one contains general information about the SNP, including its identifier, its alleles, and its position in the gene (or genes) it belongs to. The second portion describes the protein domains that this SNP belongs to, according to SWISS-PROT. The next section lists all submissions for this SNP, and provides the dbSNP submission identifier, the submitter's name and the private SNP identifier. The "Tools" section contains links to various PCR primer design programs, and to a facility to export the data shown in this page in XML format. Finally, the flanking sequence for this SNP is shown, up to a maximum of 10,000 nucleotides.
