Recombination between the two progenitor insertions (PBac{WH}Ptp4Ef02952 and PBac{WH}f06356) has resulted in deletion of the sequence between them. The deletion removes the four most distal enhancers (DG2, DG3, Z and A) of the svb regulatory region.
If no genes are listed here, it may be because the affected region is very large.
The JBrowse insert above may show an error for the same reason,
and other FlyBase tools such as CytoSearch may also fail for large regions.
You can contact FlyBase for more help.
In these cases, there will be no "Export to Hitlist" button to the left.
