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

    The combination Df(2L)gcm2/Df(2L)200 is lethal. The Df(2L)gcm2/Df(2L)200 embryos show glial cell deficiencies, especially in the longitudinal tracts (6.4 longitudinal glia are seen per hemisegment compared to 8.5 per hemisegment in wild-type embryos).

    (Alfonso and Jones, 2002)
    NOT in combination with other aberrations

    Df(2L)gcm2 embryos do not exhibit a defect in crystal cell development.

    (Bataille et al., 2005)

    Viable.

    Df(2L)gcm2 mutant larvae show no glial defects in the optic lobe.

    (Chotard et al., 2005)

    Homozygous viable. Homozygous embryos show a 25% reduction in the number of crq-positive hemocytes compared to wild-type and a 26% reduction in Pxn-positive hemocytes compared to wild-type.
