The Genome Variation Server (GVS), fed by a local database, enables rapid access to human genotype data found
in dbSNP, and provides tools for
analysis of genotype data. The current release of genotype data found in the GVS database is that of dbSNP build 138 (July 2013).
The variation locations are mapped to the human genome reference sequence of February 2009 (UCSC hg19, NCBI build 37).
This GVS database contains 11.7 million variations with corresponding genotype data.
To be included in our database, a variation must have genotype data, and it must be uniquely mapped to the human genome by dbSNP.
As most submitters to dbSNP report double genotypes for X and Y chromosome variations, we put double genotypes in our
database, and changed single genotypes to (homozygous) double genotypes. If a genotype on the Y chromosome was reported to be heterozygous, we
omitted it. We have not corrected the frequencies for male X chromosome genotypes.
A list of the files from which the database has been built can be found here.
The GVS will continue to be updated with new analysis features and with more genotype data as it becomes available.
