Abstract excerpt

Attention Deficit/Hyperactivity Disorder (ADHD) remains a neurodevelopmental condition with an incompletely understood etiology, despite evident genetic influences. Disruptions in the circadian cycle and sleep disturbances have been implicated in ADHD. This case-control study aimed to examine the presence of genetic polymorphisms in circadian cycle genes among ADHD patients. Using TaqMan real-time PCR, eight SNPs...
