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.

    NOT in combination with other aberrations

    Flies heterozygous for the deletion do not show a Minute bristle phenotype.

    (Marygold et al., 2007)

    Df(1)JA26 hemizygous embryos exhibit head and thorax defects similar to tsg loss of function mutants.

    With a very low penetrance, Df(1)JA26 hemizygous embryos show subtle defects in segmentation, including partial fusion of denticle band pairs in the register seen for Ten-m mutants.

    (Rakovitsky et al., 2007)

    Heterozygous P1 stage pupae have a significantly increased heart rate and an increased strength of heart beat rhythmicity compared to controls.

    (Ray and Dowse, 2005)

    Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.

    (Coyne et al., 1998)

    Initially showed maternal enhancement of dpphr4, but effect not due to disruption of discrete element within the deficiency.

    (Nicholls and Gelbart, 1998)

    Deficient embryos show an uninterpretable mutant midgut phenotype.

    (Bilder and Scott, 1995)

    Homozygous embryos are very abnormal compared to wild-type.

    (Harbecke and Lengyel, 1995)

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

    (Pauli et al., 1995)

    No significant change in female lethality when in combination with Sxlf1.

    (Anand and Chandra, 1994)
