![]() If you click on the center, the cross-shaped icon will display indicating you can drag the view left or right. Locate the blue-colored section indicating the cytogenetic band(s) being displayed. The chromosome overview - or ideogram - atop the page supports both changing the range of the display, and moving the range of the display. These include navigation by cytogenetic band supported by the horizontal ideogram display at the top of the page by gene in the blue bar by exon in the selected gene in the blue bar, modifying zoom level or panning in Sequence Viewer, clicking on a feature in Sequence Viewer, etc. There are multiple tools provided to support navigation on the sequence being displayed. Select a gene from the drop down menu to navigate to it. The "History" section displays your recent gene searches. Note that the results section has two tabs, one for genes and one for all other features. If multiple results are returned by your query, select one for display by clicking on its row in the results under the search box. Additional gene search examples can found here.Note that base pairs (bp) can be writen out, or abbreviated (K for kb, M for Mb) To limit the scope of the display by size, indicate the size after a slash (/) as in the "chr1:1,500,000 / 200". An asterisk (*) can be used as a wild card for gene symbols only. Here you will note that Variation Viewer supports queries by location in multiple formats, by cytogenetic band, gene symbol, or dbSNP ID (rs number) or dbVar ID (esv and nsv number). ![]() When you move your cursor to the area of the search box, note that the option 'Search examples' is displayed. Variation Viewer supports both the current and previous versions of the reference human genome assembly - GRCh38 and GRCh37.p13.Įnter your query in the input box in the Search section. Select the assembly to query in the Pick Assembly section. You can locate regions of interest through the control panel at the upper left of the page.
