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

    Heterozygotes show disrupted hygrosensing behaviour; a higher fraction of flies choose moist air (100% humidity) over dry air (0% humidity) compared to wild-type controls in a hygrosensory behaviour assay after five minutes. Heterozygotes show an impaired electrophysiological response to moist air, while leaving dry air sensing unaffected (recordings were taken at the base of the 2nd antennal segment in these experiments).
