Database of Genomic Variants archive
DGVa is a central archive that receives data from, and distributes data to, a number of resources. The DGVa accepts direct submissions from researchers and accession numbers for data objects included in these are given the prefix 'e'. The DGVa also exchanges data on a regular basis with dbVar (a peer archive hosted by NCBI in the USA). Data objects accessioned by dbVar have the prefix 'n'. You can retrieve DGVa data from the data download page, search the DGVa using Biomart, and view the data in a genomic context using Ensembl. The DGVa also supplies data to DGV (Database of Genomic Variants, hosted by The Centre for Applied Genomics in Canada), where further curation and interpretation is carried out.
