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
    NOT in combination with other aberrations

    The Df(2L)sc19-5 chromosome acts as a dominant weak 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)

    Weak second site non-complementing phenotype with zipEbr and zipmhc-c6.1 : malformed phenotype penetrance 10-24%.

    (Halsell and Kiehart, 1998)

    Sterile and reduced viability.
