FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
Grasp65unspecified null flies are viable, but the females are sterile. Germline mosaic analysis reveals that Grasp65unspecified null mutant clones result in sterility.
The architecture of somal Golgi in Grasp65unspecified null mutant larval dendritic arborization neurons appears normal.
