The dyskinesias are managed by decreasing the daily levodopa dose in Parkinson’s disease patients with end-of-dose fluctuations. A functional single-nucleotide polymorphism a common normal variant of the gene for catechol-O-methyltransferase results in a valine to methionine mutation at position Val Met rs As the regulation of catecholamines is impaired in a number of medical conditions, several pharmaceutical drugs target COMT to alter its activity and therefore the availability of catecholamines.


Inyibidores acts mainly peripherally whereas tolcapone acts both peripherally and centrally. This page was last edited on 21 Novemberat In other projects Wikimedia Commons. The effect size of genotypic moderation was quite large: Principles of pharmacology 3rd ed. The gene variant has been shown to affect cognitive tasks broadly related to executive functionsuch as set shifting, response inhibition, abstract thought, and the acquisition of rules or task structure.

Levodopaa precursor of catecholamines, is an important substrate of COMT. Given the preferential role of COMT in prefrontal dopamine degradation, the ValMet polymorphism is thought to exert its effects on cognition by modulating dopamine signaling in the frontal lobes.

Thus, COMT inhibitors are clinically significant and beneficial adjunct to levodopa therapy in Parkinson’s disease patients with end-of-dose fluctuations. COMT is the name given to the gene that codes for this enzyme. Oroszi G, Goldman D December Histamine N-methyltransferase Diamine oxidase.

Temporomandibular joint dysfunction TMD does not appear to be a classic genetic disorder, however variations in the gene that codes for COMT have been suggested to be responsible for inheritance of a predisposition to develop TMD during life.
