© 2023, The Author(s), under exclusive licence to Springer Nature B.V.Background: In vitro studies have shown that the functional − 1478CA > del polymorphism (rs33989964) of the suppressor of cytokine signaling (SOCS)-1 gene is associated with an altered trascriptional activity. Here, we sought to examine the potential association of this polymorphism with the risk of gastric cancer (GC) and to analyze its prognostic impact on overall survival (OS). Materials and methods: The study cohort consisted of 74 Turkish patients with GC and 52 healthy controls. Genotyping of the SOCS-1 -1478CA > del polymorphism was carried out using restriction fragment length polymorphism analysis. Results: After allowance of age and sex, multivariable logistic regression analysis revealed that the carriage of the del allele of the SOCS-1 -1478CA > del polymorphism was independently associated with an increased risk of GC (odds ratio = 6.78, 95% confidence interval = 3.24–10.99, P < 0.001). Kaplan-Meier analysis revealed no significant differences in OS for patients harboring at least one del allele of rs33989964 compared with CA/CA homozygotes (log-rank test, P = 0.17). Conclusion: While the SOCS-1 -1478CA > del polymorphism is significantly associated with the risk of GC in the Turkish population, it does not affect OS.
