Variant View Software


Variant View is a visualization tool for analyzing genetic sequence variants.

Variant View is useful to domain experts in several ways: First, it integrates diverse data types previously distributed across input files and external databases. Second, it provides summary metrics that are valuable for sorting genes and identifying candidates for further exploration. Third, it displays rich information about variant type and distribution across a gene. This information is not available in any other visualization tool and is valuable for interpreting the biological impact of variants, which requires human inspection.

Variant View was implemented using a combination of HTML, CSS, JavaScript, and the JavaScript library visualization toolkit D3 (Data Driven Documents).


You can try Variant View by navigating to the Variant View Demo Page. The sample variant data set for this demo is provided by Dr. Linda Chang and Dr. Gerben Duns. All patient ids have been sanitized. Any names that appear in the data set are made-up.


Instructions for how to run and use Variant View are found in the READ_ME.txt file included in the software package.
