Abstract excerpt

Genes involved in melatonin synthesis, such as Aa-nat, may be important for our understanding of diurnal preference and circadian rhythm disturbances in humans. In Japan, Hohjoh et al. reported increased allelic frequencies of the 619A allele of the G619A Aa-nat gene polymorphism in a sample of Delayed Sleep Phase Syndrome (DSPS) patients. The present study sought to analyze G619A polymorphism frequency in a...
