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.

    NOT in combination with other aberrations

    Mutant animals exhibit defects in axonal projections

    Shows no maternal enhancement of dpphr4.

    Dominantly causes tergite defects in less than 50% of run3 heterozygotes.

    Deficient embryos show an uninterpretable mutant midgut phenotype.

    Homozygous embryos do not complete head involution, tracheae are disconnected and salivary glands are bulgy. Formation and maintenance of the midgut epithelium is variable, and midgut constrictions do not form.

    Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.

    Reduced ventral cord.

    Other Comments
     

    The Df(2R)eve chromosome acts as a dominant moderate suppressor of telomeric silencing (assayed using the effect of the chromosome on the eye colour phenotype of flies carrying "P{wvar}KR3-2", a stable "brown-red" variant of the P{3'WP-2,wvar}2Lt insertion), but this is a false positive result (the suppressor is not within the bounds of the deficient region) because the region of the deficiency is covered by one or more nonsuppressing deficiencies. The suppressor maps to the tip of 2L rather than to the site of the deficiency.
