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

    Dp(1;Y)shi+1/Df(1)19 larvae lack the mouth hooks and cirri and the lateral process is shortened. The H-piece and hypostomal sclerites are absent and the antennal sense organ is not usually seen.

    (Mahaffey et al., 2001)
    NOT in combination with other aberrations

    Heterozygosity for this deletion enhances the mutant ovarian phenotype of ovoD2.

    (Pauli et al., 1995)

    Homozygous and hemizygous embryos fail to hatch to the first instar larval stage. CNS is normal but Bolwig photoreceptor cells are defective.
