The Role of the Catechol-O-Methyltransferase (COMT) Gene in Personality and Related Psychopathological Disorders
Abstract:This review provides a short overview of the most significant biologically oriented theories of human personality. Personality concepts of Eysenck, Gray and McNaughton, Cloninger and Panksepp will be introduced and the focal evidence for the heritability of personality will be summarized. In this context, a synopsis of a large number of COMT genetic association studies (with a focus on the COMT Val158Met polymorphism) in the framework of the introduced biologically oriented personality theories will be given. In line with the theory of a continuum model between healthy anxious behavior and related psychopathological behavior, the role of the COMT gene in anxiety disorders will be discussed. A final outlook considers new research strategies such as genetic imaging and epigenetics for a better understanding of human personality.

- CNS & Neurological Disorders - Drug Targets aims to cover all the latest and outstanding developments on the medicinal chemistry, pharmacology, molecular biology, genomics and biochemistry of contemporary molecular targets involved in neurological and central nervous system (CNS) disorders e.g. disease specific proteins, receptors, enzymes, genes. Each issue of the journal will contain a series of timely in-depth reviews written by leaders in the field covering a range of current topics on drug targets involved in neurological and CNS disorders. As the discovery, identification, characterization and validation of novel human drug targets for neurological and CNS drug discovery continues to grow; this journal will be essential reading for all pharmaceutical scientists involved in drug discovery and development.
