Circadian clocks are driven by signals from the habitat to match the solar day and to reset their phase relative to local time. A key function of the circadian clocks allows individuals to anticipate routine environmental conditions and to adjust their behaviors to the change of conditions. In clinical practice mood, anxiety and alcohol use disorders are often comorbid conditions. Clinical data have demonstrated that there are abnormalities in the circadian rhythms in patients with mood disorders and those with alcohol use disorders. Recent findings of molecular genetics have yielded the first insight into the targets of interest. Circadian clock gene variants are a fruitful target for elucidation of the pathogenesis. The findings that have gained support indicate that genetic variants of RORA (rs2028122) and CRY1 (rs2287161) associate with depressive disorder, those of RORB (rs7022435, rs3750420, rs1157358, rs3903529) and NR1D1 (rs2314339) with bipolar disorder, and those of NPAS2 (rs11541353) and CRY2 (rs10838524) with seasonal affective disorder or winter depression. Concerning anxiety disorders and alcohol use disorders, the current findings are preliminary and need further verification to explain the association of ARNTL2, being suggestive only, with social phobia (rs2306073) and with alcohol abuse (rs7958822, rs4964057).

RAR-related orphan receptors A (RORA) and B (RORB) and voltage-gated sodium channel type 1 (SCN1A) genes play critical roles in the regulation of the circadian clock. Evidence has shown an association of RORA and RORB polymorphisms with susceptibility to autism and depression. Hence, we tested the association of RORA rs12912233, rs16943429, rs880626, rs2290430, and rs12900948; RORB rs1157358, rs7022435, rs3750420, and rs3903529; and SCN1A rs3812718 with epilepsy risk in the Malaysians. DNA was genotyped in 1789 subjects (39% epilepsy patients) by using MassARRAY (Sequenom). Significant association was obtained for rs12912233 in Malaysian Chinese (p=0.003). Interaction between rs12912233-rs880626 and rs3812718 was associated with the epilepsy risk in the subjects overall (p=0.001). Results show that RORA rs12912233 alone might be a possible risk variant for epilepsy in Malaysian Chinese, but that, together with RORA rs880626 and SCN1A rs3812718, this polymorphism may have a synergistic effect in the epilepsy risk in Malaysians.
