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

    Homozygous viable. The block of distally located heterochromatin in In(2R)AT-4 promotes the association of this region of the chromosome with regions surrounding the centromere in interphase nuclei of homozygous larval central nervous system cells.
