Dopamine metabolism in adults with 22q11 deletion syndrome, with and without schizophrenia--relationship with COMT Val¹⁰⁸/¹⁵⁸Met polymorphism, gender and symptomatology.

Abstract excerpt

22q11 Deletion syndrome (22q11DS) is a major risk factor for schizophrenia. In addition, both conditions are associated with alterations of the dopaminergic system. The catechol-O-methyltransferase (COMT) gene, located within the deleted region, encodes for the enzyme COMT that is important for degradation of catecholamines, including dopamine (DA). COMT activity is sexually dimorphic and its gene contains a...
