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

    Strong phenotypic reversion: 250--350 facets per eye. Severe embryonic phenotype: loss of ventral, lateral and majority of dorsal cuticle. Viable when heterozygous with a Dl allele.

    (Shepard et al., 1989)

    Embryonic lethal, extreme neurogenic phenotype.

    (Preiss et al., 1988)

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