Video tutorial sessions 12, 13 and 10 demonstrate some SNP retrievals.

Standard retrievals use Sanger1 (SNPs, 56+ million locations, 19 inbred strains) except for queries on rs numbers and other exact locations in which case all the larger data SNP sets are searched. For indels and SVs see below.

Navigation: Retrievals are specified using a step-by-step web interface. For best results proceed forward through the steps to the end where a result is produced. At this point you can click on "Refine your query" if necessary to go around again and make adjustments, or to begin a new query. Try to avoid using your browser's Reload or Back buttons.

Your results will be a viewable HTML list or the result can be downloaded as a CSV or text file. Haplotype strain grouping views and polymorphism matrix views are also available.

Genomic region: Enter gene or marker symbols, GRCm38 chr locations, or rs numbers. Use spaces or returns to separate items. Upper/lower case doesn't matter.
• Gene and marker symbols must use current MGI nomenclature.   Find genes
• Recognized symbols include genes, Mit markers, miRNA and QTLs.
• For best results lists of genes should be cleaned using MGI batch query.
• Coordinates may be bp or Mbp and may include embedded commas
• For an exact location use rs number or coordinates e.g. 1:4834655
• For an entire chromosome use e.g. 3:all   For entire genome use: all.
      (these cannot be used with the 5 largest data sets however)
• Don't mix exact locations (such as rs numbers) with genes or ranges
• See also the SNP retrieval examples page


Y and MT coverage: Most data sets cover chromosomes 1 through X. For Y coverage use Perlegen2 or CGD-MDA1. For MT coverage use Perlegen2.

Additional flank can be specified and will apply to each genomic region given. For genes, "upstream" is the region adjacent to the 5' end. For other entities such as Mit markers, rs numbers and basepair specifications, "upstream" will refer to the adjacent region with lower basepair coordinates.

Retrieving indels or SVs: Use the Choose Data Sets selection, then see Sanger2, Sanger3, and Amgen1 data sets. The majority of data in this resource are SNPs. [More info on MPD representation of indels and SVs]

Variation effect filter allows locations to be retrieved based on annotated variation status such as coding, UTR, splice, noncoding transcript, intronic, or intergenic. Also useful for significantly paring down results where appropriate.

Query size limitations
  • Up to 100 gene symbols, rs numbers, or chromosome locations can be entered into the region box for standard (Sanger1) retrievals.
  • Up to 50 Mbp can be retrieved from Sanger1 if specific variation effects (non-intronic) are selected.
  • Up to 10 Mbp can be retrieved from Sanger1 if no constraints are specified.
  • Up to one entire chromosome can be retrieved from the other large data sets.
  • Limits may vary depending on the situation.... and will be indicated when exceeded.

    Automated usage is prohibited. All usage of this resource must be by live interactive users via our web page interface. Usage judged to be violating this policy is subject to blockage. Consider file downloads (above) as an alternative.

    For info on interpreting these data and caveats, please see the resource documentation.
