Inserted 8859bp downstream from the start of the Hnf4 first exon.
Most ventral nerve cord commissures are missing in stage 17 GS(2)A096GS-A096; Scer\GAL4sca-4512 embryos. The few commisures that do form are abnormally thin. Facscicles within the longitudinal connectives are fused in places and the lateral most of these have occasional gaps. RP1 neurons fail to cross the midline in these embryos.

Unclear if phenotypes are due to overexpression of Hnf4 or CG9314.
