Csnk1etm1Asil mutation (1 available); any Csnk1e mutation (30 available)
♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
behavior/neurological
shortened circadian behavior period ( J:135186 )
• significant shortening of circadian period of behavior in vivo in a gene dose-dependent manner
• homozygous mice have 3.6 hr shorter circadian period than wild-type
• mutant mice are viable and fertile with no overt deleterious phenotype

nervous system
abnormal neuron physiology ( J:135186 )
• significant shortening of circadian period of suprachiasmatic nucleus firing rates in vitro in a gene dose-dependent manner
