摘要：

The human tryptophan hydroxylase (TPH) gene, the rate-limiting enzyme in serotonin biosynthesis. was localized on human chromosome 11p14-p15.3. Variation within intron 7 of the TPH gene was found to influence serotonin metabolism in the brain. To explore the possible role of TPH in the pathogenesis of schizophrenic disorders, we genotyped the TPH A218C polymorphism in 196 schizophrenic patients and 251 controls. The results demonstrated that genotype distribution was significantly different between schizophrenic patients and control subjects (P = 0.002). No association was found between TPH genotypes and suicidal history in schizophrenic patients (P = 0.239). The positive finding in this study suggests that the TPH 218A allele is a risk factor for schizophrenic disorders or is in linkage disequilibrium with the putative schizophrenia susceptibility locus in Han Chinese population.
