Underlying mechanism of schizophrenia has been linked to immune dysregulation in central nervous system. IL-10 is one of anti-inflammatory cytokines in which its secretion is regulated by genetic variation. Thus, we aim to investigate allelic and genotypic variation of IL-10 gene in Bataknese with schizophrenia compared to healthy control. Method: This study is a comparative observational study with a case-control design. Blood samples were taken from a total of 194 subjects (n = 97 for each case and control group), then identified the IL-10 allele and genotype (-1082 G/A) using the Polymerase Chain Reaction- Restriction Fragment Length Polymorphism (PCR-RFLP). Result: The difference in the proportion of sex was found to be statistically significant (p = 0.008), in which male was more often found in the case group. The mean age in the case group was 34.27 + 6.85, and were more likely to be unemployed and did not attend higher education (p = 0.001). Identification of allele variation showed that the dominant allele in the Batak tribe was allele A (91.6% in ODS, and 81.0% in control). The proportion of AA genotypes in ODS was 84.5% and in controls was 81.0%. Homozygous GG genotypes were not found in either group. Individuals with the A allele and the AA genotype were more common in the ODS group (p = 0.018 and 0.011, respectively). Individuals with the A allele had a 2.26-fold higher risk of developing schizophrenia (OR = 2.26, 95% CI = 1.1825 ? 4.3559) and individuals with the AA genotype also had a 2.56 times higher risk of developing schizophrenia ( OR = 2.56, 95% CI = 1.280 ? 5.152). There was no difference in onset based on genotypic variation (p = 1.00). Conclusion: Allelic and genotypic variation of the IL-10 (-1082 G/A) was found between Bataknese with schizophrenia and healthy control. A allele and AA genotype serve as contributing risk factor of developing schizophrenia.} }
