OBJECTIVE@#To study the distribution of the tryptophan hydroxylase (TPH) gene-T457C locus polymorphism in Han ethnic group in northern China and to find its applicable value in forensic science.@*METHODS@#Genomic DNA samples, extracted from 180 unrelated individuals in northern Chinese Han population, were analyzed by PCR-RFLP.@*RESULTS@#The discrimination power (DP) value and the power of exclusion (PE) value of the TPH gene-T457C locus were 0.624 and 0.187, respectively. The allele frequency showed significant difference from that of French people (P=0.04).@*CONCLUSION@#Polymorphism of the TPH gene-T457C locus could show ethnic and regional differences. It has a potential to be used in forensic science.
