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

    No effect on In(1)wm4h position-effect variegation. Suppresses the Minute phenotype of Df(2L)M24F11.

    No suppressor effect on w variegation of flies carrying In(1)wm4h.

    (Reuter and Szidonya, 1983)

    Suppresses variegation of In(1)wm4.

    NOT in combination with other aberrations

    Homozygous lethal.
