First off, let me just say that when you click onto this site, the username is “guest”, and the password field is left blank. (In reading that first sentence, you have just saved yourself a lot of frustration.) SNPper is a database of single nucleotide polymorphisms (though I happen to think that it would make a great name for a barber shop, as well). There is no shortage of SNPs in this database—it houses 9,163,169 to be exact—and there are multiple ways to use this online resource. You can search by the name of the SNP, by position on a specific chromosome, or you can input a name of a gene to find all known SNPs associated with it. There is a fair amount of background information on the site, including how the database was constructed and what types of data are included. As an added bonus, the website includes other analysis tools such as the GeneOntology browser and amino acid properties table.
