Differential Genetic and Epigenetic Regulation of Catechol-O-Methyl-Transferase (COMT) is Associated with Impaired Fear Inhibition in Posttraumatic Stress Disorder

Differential Genetic and Epigenetic Regulation of Catechol-O-Methyl-Transferase (COMT) is Associated with Impaired Fear Inhibition in Posttraumatic Stress Disorder

The catechol-O-methyltransferase (COMT) enzyme is critical for the catabolic regulation of synaptic dopamine, resulting in altered cortical functioning. The COMT Val158Met polymorphism has been implicated in human mental illness, with Met/Met homozygotes associated with increased susceptibility to...
