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

    Inviable in combination with In(1LR)pn2a or In(1)r20.

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

    Has no "Enhancer of sev" activity.

    (Allard et al., 1996)

    Mutation changes the level of w expression in ph-plac+3 flies; eye colour is darker.

    (Fauvarque et al., 1995)

    Extensive cell death occurs in the embryonic ventral epidermis.

    (Simon et al., 1992)

    Lethality occurs during the embryonic stage. Phenotype of homozygous germ line clones is lethal.
