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

    Effect on variegation of y in In(1)y3P and Sb in T(2;3)SbV studied: inactivation of y occurs independently of inactivation of Sb.

    (Bishop, 1992)
    NOT in combination with other aberrations

    Enhancer of variegation.

    (Tartof et al., 1989)

    Homozygous lethal. General enhancer of position effect variegation: significantly enhances the mutant variegated phenotype of In(1)wm4, In(1)y3P, C(1;YL)wmMc and T(1;4)wm5. Position effect variegation at the w locus is not seen when Dp(2;2)E(var)29A-19 is combined with In(1)wm4rv5, In(1)wm4rv6 or In(1)wm4rv26.

    (Locke et al., 1988)

    Enhances position-effect variegation of In(1)wm4. Recessive lethal.
