Polymorphism of TPH gene T3792A locus in Han ethnic group of north China / 法医学杂志

ABSTRACT

OBJECTIVE@#To investigate the polymorphism of the TPH gene T3792A locus in Han ethnic group of north China and its application value in forensic science.@*METHODS@#The polymorphism of T3792A locus of the TPH gene was analyzed by the ASPCR of blood samples from 173 unrelated individuals of north Chinese Han population.@*RESULTS@#The distribution of the T3792A locus polymorphism of the TPH gene in Han ethnic group of north China followed the Hardy-Weinberg law, with the allele A and T gene frequency of 0.486 and 0.514, respectively.@*CONCLUSION@#The TPH gene T3792A locus shows a very good genetic polymorphism, and may be applied to individual identification and paternity testing.
