ABSTRACT
<p><b>OBJECTIVE</b>To assess the associations between schizophrenia and six functional genes dopamine D2 receptor gene (DRD2), dopamine D4 receptor gene (DRD4), 5-hydroxytryptamine 2A receptor gene (5-HT2A), 5-HT6 receptor gene (5-HT6), catechol-O-methyltransferase gene (COMT) and dopamine transporter gene (DAT1).</p><p><b>METHODS</b>With the techniques of Amp-RFLP and Amp-FLP, association analysis was made between schizophrenia and the six genes in 67 schizophrenic patients from Chinese Han population.</p><p><b>RESULTS</b>(1) Neither genotypes nor alleles of DRD2, 5-HT2A, 5-HT6 and COMT gene showed significant differences between patients and controls (P>0.05). (2) Six repeats (6R) in DRD4 gene, the allele of 480 bp and the genotype of 480/520 in DAT1 gene were found to be of significant differences between the two groups (P<0.05). (3) Only one negative association was observed between the 480 bp allele of DAT1 gene and schizophrenia (OR=0.441, 95% CI0.202-0.963, Z=2.05, P<0.05).</p><p><b>CONCLUSION</b>The 480 bp allele of DAT1 gene is negatively associated with schizophrenia in Chinese Han population, which stands for the dopamine hypothesis of schizophrenia.</p>
