Virtual Variants

The virtual variant feature allows you to add new variants to a case, either to refine the boundaries of a variant you have reviewed in IGV or to create a single variant that overlaps separate adjacent variant calls.

Virtual variants are listed in the grid in purple text. Grid data contain only annotation information. The call details and metrics are available only for the original calls, which are listed in the grid without modification.

For information about viewing data in IGV, see IGV Visualizations.

The virtual variant feature only supports creation and modification of CNVs. Other variant types are not currently supported.
