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

    Complements T(2;3)DTD46.4.

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

    The Df(3R)e-N19 chromosome does not act as a dominant 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).

    (Mason et al., 2004)

    Macrophages fail to migrate along the ventral cord in homozygous embryos, with much of the ventral abdomen remaining free of macrophages at stage 13-15.

    (Paladi and Tepass, 2004)

    Homozygous embryos have abnormal gut morphology.

    (Merabet et al., 2002)

    No second site non-complementing phenotype with zipEbr and zipmhc-c6.1.

    (Halsell and Kiehart, 1998)

    Shows no maternal enhancement of dpphr4.

    (Nicholls and Gelbart, 1998)

    Wild type nonanol phenotype; repulsion.

    (Cobb, 1996)

    Deficient embryos show an uninterpretable mutant midgut phenotype.

    (Bilder and Scott, 1995)

    Homozygous embryos show incomplete tracheal formation. Midgut primordia do not fuse and Malpighian tubules are variable in length.

    (Harbecke and Lengyel, 1995)

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