Association of ARNTL and PER1 genes with Parkinson's disease: a case-control study of Han Chinese.

ABSTRACT: Circadian disruptions may result in sleep problems, oxidative stress and an altered inflammatory response. These symptoms may contribute to PD pathogenesis, despite a lack of direct experimental evidence supporting this relationship. Clock genes are essential to drive and maintain circadian rhythm. To elucidate the possible role of circadian disruptions in PD, we investigated 132 tag variants in eight clock genes. We genotyped these tags within 1,394 Chinese cases and 1,342 controls using Illumina GoldenGate chips. We discovered that SNPs in ARNTL (rs900147, P = 3.33 × 10(-5), OR = 0.80) and PER1 (rs2253820, P = 5.30 × 10(-6), OR = 1.31) genes are significantly associated with PD risk. Moreover, the positive association of the ARNTL rs900147 variant was more robust in tremor dominant (TD)
