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

    Embryonic lethal. Trunk ventral denticle belts are disorganized. Dorsal and ventral parts of the prothorax are deleted. Ectopic papilla-like sense organs differentiate in the thorax region. The anal opening is sclerotized. Neuronal defects: disruption or deletion of ventral groups of neurons in the trunk region and misrouting of axons towards the head.
