Twelve-nucleotide repeat polymorphism of D4 dopamine receptor gene in Chinese familial schizophrenic patients.

Biological psychiatry - 15 Mar 1998

Hong C J, Chiu H J, Chang Y S, Sim C B

Abstract excerpt

BACKGROUND: Disturbances in dopaminergic transmission have been implicated in the etiology of schizophrenia. Catalano et al reported an association between delusional disorder and the number of a 12-nucleotide (bp) repeat sequence in the first exon of dopamine D4 receptor gene (DRD4), which indicated a possible role of this polymorphism in the pathogenesis of psychotic disorders. METHODS: DNA of 42 Chinese...
