abstract = {The gene Disrupted in Schizophrenia-1 (DISC1) is linked to
a range of psychiatric disorders. Two recent transgenic
studies suggest DISC1 is also involved in homeostatic sleep
regulation. Several strains of inbred mice commonly used for
genome manipulation experiments, including several Swiss and
likely all 129 substrains, carry a natural deletion mutation
of Disc1. This constitutes a potential confound for studying
sleep in genetically modified mice. Since disturbed sleep
can also influence psychiatric and neurodegenerative disease
models, this putative confound might affect a wide range of
studies in several fields. Therefore, we asked to what
extent the natural Disc1 deletion affects sleep. To this
end, we first compared sleep and electroencephalogram (EEG)
phenotypes of 129S4 mice carrying the Disc1 deletion and
C57BL/6N mice carrying the full-length version. We then bred
Disc1 from C57BL/6N into the 129S4 background, resulting in
S4-Disc1 mice. The differences between 129S4 and C57BL/6N
were not detected in the 129S4 to S4-Disc1 comparison. We
conclude that the mutation has no effect on the measured
sleep and EEG characteristics. Thus, it is unlikely the
widespread Disc1 deletion has led to spurious results in
previous sleep studies or that it alters sleep in mouse
models of psychiatric or neurodegenerative diseases.},
