association of 757 c/t polymorphismin prodh gene with schizophrenia in iranian population

evidence is emerging for the association of polymorphisms in prodh gene and increased risk of schizophrenia. in this project, peripheral blood sampling was obtained from 175 schizophrenia patients that their diseases were confirmed by psychiatrists. 185 healthy individuals were considered as control group. the related tests were administered on the basis of pcr-rflp. in the continuation, statistical analysis was made on the basis of obtained genotypes from two groups of healthy and patient groups using spss16.0 software. the administration of this project aims at investigating the hypothesis that proline dehydrogenase gene, as one of the most important genes involved in schizophrenia incidence which is proved in various populations [outside iran], may also be involved in incidence of schizophrenia in iran. this study has analyzed one single nucleotide polymorphism in the prodh gene, including 757c/t in the incidence of this disease in the given statistical population. according to our results, snp 757 c/t may be effective in incidence of the disease since p value was < 0.01. ultimately, our results suggest that outbreak of mutation in prodh gene in our population can be one of causes of increasing risk of schizophrenia in this population.
