myvariantviewer

A JBrowse plugin that fetches info from MyVariant.info, MyGene.info, and CIVIC and displays it.

Example configuration

Fetch genes and variants from hg19:

  {
     "label" : "MyGene.info",
     "storeClass" : "MyVariantViewer/Store/SeqFeature/Genes",
     "urlTemplate" : "http://mygene.info/v2/query?q=hg19.{refseq}:{start}-{end}&fields=all&email=colin.diesh@gmail.com&size=1000",
     "subParts" : [
        "exon"
     ],
     "type" : "CanvasFeatures",
     "hg19" : true
  },
  {
     "label" : "MyVariant.info"
     "storeClass" : "MyVariantViewer/Store/SeqFeature/Variants",
     "urlTemplate" : "query?q={refseq}:{start}-{end}&size=1000&fetch_all=true&email=colin.diesh@gmail.com",
     "baseUrl": "http://myvariant.info/v1/",
     "type" : "CanvasFeatures",
  },
  {
     "label" : "CIVIC",
     "storeClass" : "MyVariantViewer/Store/SeqFeature/CIVIC",
     "type" : "CanvasVariants",
     "onClick": {
         "action": "iframeDialog",
         "url": "https://civicdb.org/events/genes/{gene_id}/summary/variants/{id}/summary"
     }
  },

Also note that a name store can be configured for querying myvariant.info via the search box as well

"names": {
    "type": "MyVariantViewer/Store/Names/REST",
    "url": "http://myvariant.info/v1/query"
}

Only query from a specific data source

Example to only query variants from clinvar (combining the exists-in clinvar query with fields=clinvar return values)

  {
     "storeClass" : "MyVariantViewer/Store/SeqFeature/Variants",
     "baseUrl" : "http://myvariant.info/v1/",
     "urlTemplate" : "query?q={refseq}:{start}-{end} AND _exists_:clinvar&size=1000&fetch_all=true&email=colin.diesh@gmail.com&fields=clinvar",
     "type" : "CanvasFeatures",
     "label" : "MyVariant.info clinvar"
  }

See https://github.com/cmdcolin/myvariantviewer/blob/master/test/ for test data on hg19 and hg38

Notes

Currently tested with v2 and v3 of MyGene.info and v1 of MyVariant.info on hg19 and hg38 builds. See test/hg19 and test/hg38 for sample tracks. Also works with multiple species, see test/danio for example
