Several studies have shown that polymorphisms of clock genes are associated with diurnal preferences. We investigated whether other polymorphisms also are related to diurnal preference. Our examination targeted the region around the phosphorylation site of hPer2, as a previous report has shown that one single nucleotide polymorphism (SNP) at this site causes familial advanced sleep phase syndrome...
We tested whether the human period 2 gene (hper2), one of the essential components of the circadian oscillator, might have influence on bipolar disorder. We screened 88 bipolar disorder patients and 127 controls, all of Japanese origin. Screening in the casein kinase I epsilon (CKIϵ) binding region of hper2, which was previously reported in familial advanced sleep-phase syndrome patients, with polymerase...
