N normal phenotype
adipose tissue
• decreased intra-abdominal fat noted in 2 of 3 mutants during CAT-Scan
• DEXA analysis reveals decreased total body fat in the male mutants

behavior/neurological
• female homozygous mutant mice exhibit increased locomotor activity during home cage activity testing
• homozygous knockout mice exhibit higher activity during the dark phase (mouse subjective day) of the 12:12 L:D cycle in a home-cage environment, and the greater amount of locomotor activity during subjective day persisted into a D:D (24 hour dark cycle) challenge in females
• total waking time of homozygous mice in the 12 hour dark phase was greater, to 125.6%, compared to those of WT littermates
• NREM and REM sleep times were diminished, to 54.9% and 41.1%, respectively, compared to those of WT littermates
• knockout mice had significantly longer waking and shorter NREM times from the third through the seventh, and also the twelfth hour after the onset of darkness

hematopoietic system
• homozygous mutant mice exhibit an increased mean absolute monocyte count when compared with controls

immune system
• homozygous mutant mice exhibit an increased mean absolute monocyte count when compared with controls
