✦ Synopsis

reported identifying one missense nucleotide mutation from C to G resulting in a substitution of serine with cysteine at codon 311 in the third intracellular loop of the dopamine D2 receptor in schizophrenics. Arinami et al. 119941 reported finding a positive association between the Cys311 variant and schizophrenia. In response to the report by Arinami et al. [19941 we examined 106 unrelated Japanese schizophrenics and 106 normal controls to determine if there is any association of the Cys311 variant with schizophrenia. However, we found no statistically significant differences in allelic frequencies of Cys3ll between schizophrenia and normal controls. The present results as well as those of all previous studies except for that of Arinami et al.

[ 19941 indicated that an association between the dopamine D2 receptor gene and schizophrenia is unlikely to exist.
