<b>Background:</b> Schizophrenia (SCZ) is a severe<i> </i>mental illness with high heritability. This study aimed to explore the correlation between <i>MAD1L1</i>, <i>TSNARE</i> polymorphisms and SCZ susceptibility.<b></b> <b>Methods: </b>A total of 493 patients with SCZ and 493 healthy controls were included. The genotypes of <i>MAD1L1 </i>and <i>TSNARE </i>polymorphisms<i> </i>were identified by the Agena MassARRAY platform. Odds ratio (OR) and 95% confidence intervals (CIs) were tested via logistic regression analysis in multiple genetic models and different subgroups. <b>Results:</b> We observed that AG genotype of rs1107592, AG genotype of rs4976976, and CA genotype of rs67756423 decreased the susceptibility to SCZ (<i>p </i>&lt; 0.05). The stratification analysis by age showed that the TC genotype of rs12666575, AG genotype of rs1107592, and AG genotype of rs4976976 decreased the risk of SCZ individuals older than 36 years (<i>p </i>&lt; 0.05). In addition, the AG and AA genotype of rs4976976, the CA genotype of rs67756423 were associated with a lower risk of SCZ in males (<i>p </i>&lt; 0.05). In females, the TT genotype of rs12666575 in recessive model, the AG and AA-AG genotype of rs1107592 in heterozygote and dominant model, could reduce the susceptibility to SCZ (<i>p </i>&lt; 0.05). <b></b> <b>Conclusions: </b>Our results suggest that <i>MAD1L1</i> and <i>TSNARE</i> genetic polymorphisms exert a protective role in the risk of SCZ. These findings provide evidence that <i>MAD1L1</i> and <i>TSNARE</i> may serve as potential biomarkers of SCZ.
