In the field of genetics, studying the effect of various genes is crucial in translation and interpretation. Since genetic coding influences phenotypic expression, the analysis of specific genes and possible polymorphisms are relevant in the clinical setting. An example is that of personality traits, which are believed to be influenced by specific neurotransmitters, known as catecholamines. Catecholamines are chemicals released by the adrenal glands in response to stress and function as both hormones and neurotransmitters within the body. Commonly, catecholamines mediate central nervous system functions, including those of emotional responses and motor control. Including dopamine, epinephrine, and norepinephrine, the secretion and metabolism of these chemicals are thought to impact various mental functions and behaviors. The catechol-O-methyltransferase (COMT) gene is a specialized type of enzyme, involved in the degradation processes of catecholamines. This process is a necessity in the human body, as prolonged exposure to catecholamines is harmful...
