How to construct links to ClinVar

The simplest way to link to ClinVar is to link to a single VCV, or variant, page.

The base url is:

http://www.ncbi.nlm.nih.gov/clinvar/

Add either the Variation ID or the VCV accession number to the base URL. Some examples:

  • Use the Variation ID: https://www.ncbi.nlm.nih.gov/clinvar/variation/7105/
  • Use the VCV accession: https://www.ncbi.nlm.nih.gov/clinvar/variation/VCV000007105/

More customized links can be created by querying ClinVar. For example, you may want to link to all ClinVar variants in a gene or all ClinVar variants within a genomic region.

  • The result may be a single record or a set of records that satisfy the query. 
  • In this case, use the base URL and add a qualifier for the query to construct the final URL.
  • The table below summarizes some common approaches to link to ClinVar.
  • These examples are a sample only. Any field or property listed in the help documentation can be used to build a URL by combining the base URL with the qualifier.
  • You can use Advanced search to test query options and results.

If you want to search with this type of data Add a qualifier like this Example
VariationID variation/7105 http://www.ncbi.nlm.nih.gov/clinvar/variation/7105
Variation accession /variation/VCV000007105 http://www.ncbi.nlm.nih.gov/clinvar/variation/VCV000007105

Use [chrpos37] for GRCh37/hg19 and  [chrpos38] for GRCh38/hg38

Enter the range delimited by a colon (:)
