Identification of coding polymorphisms in human circadian rhythm genes PER1, PER2, PER3, CLOCK, ARNTL, CRY1, CRY2 and TIMELESS in a multi-ethnic screening panel.
Study objective: In this study, the exonic regions of the circadian rhythm genes PER1, PER2, PER3, CLOCK, ARNTL, CRY1, CRY2 and TIMELESS were re-sequenced and coding changes identified in a panel of 95 individuals varying in ethnicity.
Study participants: DNA screening panel consisting of 95 DNA samples (17 American Caucasians, 17 African Americans, 8 Ashkenazi Jews, 8 Chinese, 8 Japanese, 5 Mexican Indians, 8 Mexicans, 8 Northern Europeans, 8 Puerto Ricans, and 8 South Americans) selected from the Coriell Institute Human Variation Panel.
Results: In addition to coding changes already identified in the database dbSNP, novel coding changes were identified, including PER1: Pro37Ser, Pro351Ser, Gln988Pro, Ala998Thr; PER2: Leu83Arg, Leu157Leu, Thre174Ile, Phe400Phe, Pro822Pro, Ala828Thr, Ala861Val, Phe876Leu, Val883Met, Val903Ile, Ala923Pro; PER3: Pro67Pro, Val90Ile, His638His, Ala820Ala, Leu929Leu; ARNTL: Arg166Gln, Ser459Phe; CLOCK: Ala34Ala, Ser208Cys, Phe233Phe, Ser632Thr, Ser816Ser; TIMELESS: Met870Val and CRY2: His35His. No coding polymorphisms were identified in CRY1.
Conclusions: Considerable genetic variation occurs within the coding region of the genes regulating circadian rhythm. Many of the non-synonymous coding polymorphisms could affect protein structure/function with the potential to affect molecular regulation of the sleep/wake cycle. Many of the potential functional effects could be ethnic group specific.
