The Single-Nucleotide Polymorphism database (dbSNP) is a variation database at the National Center for Biotechnology Information (NCBI). It is a public repository of submitted nucleotide variations and is part of NCBI's search and retrieval system Entrez. This unit describes two basic protocols to search dbSNP effectively, one to perform a text-based search and another to perform a sequence-based search. The unit also describes one of the result display formats called GeneView to obtain information about all submitted SNPs in a particular gene. Curr. Protoc.
