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
    NOT in combination with other aberrations

    The number of cells in the nau-expressing muscle precursor clusters is increased compared to wild-type in homozygous embryos and in homozygous embryos derived from homozygous female germline clones (lacking both maternal and zygotic function). The medial clusters expand longitudinally.

    (Rusconi and Corbin, 1998)

    Df(3R)Espl4 gro+t10.4 clones are cell lethal

    (Heitzler et al., 1996)

    No interaction with P{sev-svp1} or P{sev-svp2} exists.

    (Begemann et al., 1995)

    Lethal in combination with gro and E(spl)1. Homozygotes have extreme neural hyperplasia and suppress the Nspl-1 phenotype.
