Comments on Cytology

One breakpoint has been localized to a 263bp region within the RpS3A gene. The sequences on either side of the breakpoint are still present in DNA from homozygous Df(4)M101-63a embryos, indicating that the aberration is not a deletion, and the lesion in RpS3A is due to either an insertion into RpS3A, or an inversion with one breakpoint located in RpS3A.

(Podemski et al., 2004)

Left limit of break 1 from polytene analysis (FBrf0022724) Right limit of break 1 from inclusion of RpS3A (FBrf0022724) Left limit of break 2 from inclusion of RpS3A (FBrf0022724) Right limit of break 2 from non-inclusion of pan (FBrf0102482)

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

    Lethal in combination with Df(4)M101-62f, Df(4)Δ3M or Df(4)Δ9M. Inferred to overlap with: Df(4)M101-62f. Inferred to overlap with: Df(4)Δ3M. Inferred to overlap with: Df(4)Δ9M.

    (Kronhamn and Rasmuson-Lestander, 1999)
    NOT in combination with other aberrations

    Flies heterozygous for the deletion show a Minute bristle phenotype.

    (Marygold et al., 2007)

    en-/en+ in combination with an unpaired wild type ci+ allele shows a ci phenotype.

    (Locke and Hanna, 1996)

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

    (Pauli et al., 1995)

    Heterozygotes have shorter bristles than wild type flies. Eclosion is delayed by 49 hours.
