Small nucleotide Polymorphism data (single nucleotide polymorphism, insertion or deletion) can be queried through GnpSNP information system. GnpSNP provide an easy tool to filter and export genotypes and markers information to refine genetics or diversity analyses.

In some species, these variations can also be found in our genome browsers and, in this case, links between both resources may exist/

GnpSNP can manage confidentiality between data: it can stores public data and private data (before publication).
