The My Variants track lets a signed-in user create, edit, and share a personal set of variant annotations directly in the Genome Browser.
Important: This feature is intended for exploratory, educational, and demonstration use only. It must not be used to enter, store, or share private patient data, identifiable clinical records, or any other protected health information. Items written to a My Variants track are stored on shared UCSC infrastructure and may be visible to other users when shared.
Each item is drawn as a standard BED rectangle using the user-selected color. A short mouseover label and a longer free-text description may be attached to each item. When the details page is opened, any overlaps with selected reference variant tracks (for example, ClinVar and dbSNP common variants) are listed for context.
New variants can be added in one of three ways from the entry form: by HGVS or item search, by a simple BED form, or by an advanced BED form that allows user-defined extra fields. A variant can also be created by drag-selecting a region on the browser image and choosing the create-variant option from the popup menu. Existing items can be edited or deleted at any time from the track's details page.
A My Variants track can be shared read-only or with edit access, either with a specific signed-in user or with anyone holding the share link. Shared tracks are loaded automatically the next time the recipient opens the Genome Browser, similar to a shared online document. The most recent write wins; there is no per-item revision history at this time.
My Variants data are stored as a per-user custom track and can be downloaded for the current assembly using the Table Browser. The data are not part of the public UCSC database and are not available through the public REST API or the bulk download server.
