Maps clinically significant variants by gene and position!
ClinVar is a freely accessible, public archive of reports of the relationships between human variations and phenotypes, with supporting evidence at NLM/NCBI. To help you access your variants of interest quickly, ClinVar is offering an experimental release of an all-new visualization tool in the search results. This graphical display provides an overview of variants when you search by gene or genomic region (Figures 1 and 2).
Currently the graphical display is implemented as an experiment and will appear for only 10 percent of searches by gene or genomic region, but the links in this post will show the display so you can try it out. Alternatively, if you would like to bring up the graphical display for your gene or genomic region search, you can edit the URL in the address bar to change the default gr=0 to gr=1. For example, the following URL with show the graphical display:
https://www.ncbi.nlm.nih.gov/clinvar/?gr=1&term=DSG2[gene]
Note that you can only get the graphical display with gene or genomic region searches. For other types of searches, you will see the table only.
Gene search display
The display for a gene search highlights small variants within the gene. Large structural variants are also marked as a single dot in the middle of the variation. The interactive display shows the placement of variants on the gene and their clinical significance and allows you to zoom in or pan right / left and limit results to variants in a chosen gene. Figure 1 shows the graphical display as it appears at the top of the search results for the desmoglein 2 (DSG2) gene and how to filter and navigate to variants of interest (Search ClinVar: DSG2[gene]).
