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

    Df(2R)ths238/Df(2R)ths238 embryos show defects in mesoderm spreading during stage 8, which results in the mesoderm forming a multilayered structure at stages 9-10 (in contrast to wild-type embryos where the mesoderm forms a single layer of cells at this stage).

    (Kadam et al., 2009)
    NOT in combination with other aberrations

    Mutant embryos show a weak but significant defect in the migration of ventral astrocytes and in the infiltration of astrocyte processes into the neuropil.

    (Stork et al., 2014)

    Df(2R)ths238/+ stage 17 embryos show a reduction in the number of longitudinal visceral muscle (LVM) fibres around the midgut, particularly in the anterior portion. In stage 11 embryos the speed of migration of the longitudinal visceral muscle (LVM) founder cells differs between the right and left sides and frequently a portion of cell occupy more medial positions, with some cells from the right and left sides coming into contact in the midline.
