Schizophrenia is a highly heritable mental disorder which can be occurred as a result of mutations or single nucleotide polymorphisms (SNPs) in various genes. Proline dehydrogenase (PRODH) gene is one of the most important genes which can be associated with increased risk of schizophrenia in several populations. Here, we considered the effect of PRODH gene polymorphisms on the incidence of schizophrenia in Iranian populations. This study was done using the analysis of 3 SNPs markers, including G1496A, G758A and C1482T. Molecular analysis was performed on 263 schizophrenic patients and 278 healthy individuals (control group). These examinations were executed by PCR-based restriction fragment length polymorphism (RFLP) technique. Statistical analysis was performed by SPSS software (16.0). Our findings showed that G1496A and C1482T polymorphisms in patients were significantly higher than controls and there were meaningful correlations between the occurrence of these polymorphisms and schizophrenia in the population (P < 0.001). However­, there was no significant relationship between G758A in the PRODH gene and schizophrenia. Haplotype analysis showed that AAT, AAC and GAT blocks (variation alleles are bold) had significant correlations with schizophrenia. PRODH gene can be considered as one of the important genes involved in schizophrenia development among the Iranian population.
