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.
Pdfrunspecified is a suppressor of abnormal sleep phenotype of wakeD2
The increase in sleep latency seen in wakeD2 flies is blocked if they are also mutant for Pdfrunspecified.
