BACKGROUND: Massive heritability occurs in schizophrenia. Gene identification which is defenceless against this disorder is difficult to be proven. The potential aspect of gen vulnerability in developing schizophrenic symptoms, for instance, is shown by several complex gene of tumor necrosis factor-alpha, interleukin (IL)-1, IL-6, and IL-10.
AIMS: The aim of the study was to investigate the relationship of gene polymorphism of interferon-gamma (IFN-γ) +874 A/T and schizophrenia symptoms to Batak’s schizophrenic patients.
METHODS: This study is a case–control study involved with 248 subjects from Prof. M. Ildrem Medan Hospital. The subjects were divided into two groups, the first group (124 subjects) was recruited as the case group, while the other 124 subjects were grouped as control cases with ages of 20–55 years of old. The case study group was hospitalized patients in the hospital, while the control group is those donors in the blood transfusion unit at Pirngadi General Hospital, Medan, Indonesia. IFN-γ +874 A/T gene polymorphism was examined by polymerase chain reaction-restriction fragment length polymorphism method.
RESULTS: Genotype AT frequencies from gen IFN-γ +874 A/T were found higher in case study than those from control groups, which were accounted for 43.5% and 41.1%, respectively, with p = 0.005, odds ratio (OR) = 2.83 95% confidence interval (CI) 1.36–5.86. The allele T was displayed higher in case group compared to control groups contributed for 46.0% and 33.5%, respectively, with p = 0.006, OR = 0.59 95% (CI) 0.41–0.85, (p = 0.006).
CONCLUSIONS: There was a relationship between gen IFN-γ +874 A/T and schizophrenia on Batak ethnicity with schizophrenic disorder. The genotype AT contributes for increasing schizoprenic risk up to 2.83 times.
