β¦ Synopsis
A mutation in the DRDS receptor gene has been reported in association with schizophrenia in Japanese and Caucasian populations. The variation, Ser to Cys at codon 311, occurs in the third intracellular loop of the receptor and is therefore putatively functional. W e report the results of screening US Caucasian schizophrenic and nonschizophrenic populations. We detected the occurrence of the DRDS Cys3ll variant in both schizophrenics and controls. Our data demonstrates no significant difference between the frequency of Cys311 in Caucasian schizophrenic and non-schizophrenic populations, indicating no association with schizophrenia.

A serine-to-cysteine mutation of dopamine D2 receptor at codon 311 (Cys311) was found to have higher frequency in schizophrenic patients than in normal controls in Japanese by Arinami et al. 11994: Lancet 343: 703-7041. The Cys311 allele was found to be associated with patients with younger ageof-on
We investigated a variant of the dopamine D2 receptor gene (Ser311/Cys311 substitution) in Caucasian patients with schizophrenia (n = 273), delusional disorder (n = 621, bipolar I affective disorder (n = 63), and controls (n = 255). No evidence for association between the receptor variant and any of
As part of the European Multicentre Association Study of Schizophrenia (EMASS), we studied polymorphisms in the dopamine DRD2 and DRD3 receptor genes. The EMASS collaboration was established to create a large, statistically powerful sample of schizophrenic patients and controls from different Europe
