Affected Genes Inferred by Location (0)
    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.
    Phenotypic Data
    In combination with other aberrations

    Df(3L)337/Df(3L)GN19 flies develop normally and are fertile. idaΔ107/Df(3L)GN19 animals show an arrest in development during the prepupal period.

    (Vaskova et al., 2000)
    NOT in combination with other aberrations

    Dominantly suppresses the KrIf-1/+ eye phenotype.

    (Carrera et al., 1998)

    Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.

    (Pauli et al., 1995)

    Df(3L)ems13/Df(3L)GN19 heterozygotes show semilethality (though have no obvious structural abnormality in first instar larvae, when most of the lethality occurs) due to deletion of ImpL2. The lethality can be rescued by an ImpL2+ transgene.
