GALNT14-rs9679162 is associated with postoperative prognosis and therapeutic responses. However, relying on one single nucleotide polymorphism (SNP) greatly limits its predictive power. This study aims to identify an SNP panel to improve prognosis prediction and explore its role in modulating tumor-infiltrating immune cells (TIICs).Patients and Methods: We included 345 HCC patients underwent surgical resection: 15 in the exploration cohort and 330 in the validation cohort. Genome-wide association study (GWAS) and PCR-based genotyping identified SNPs in linkage disequilibrium (LD) with rs9679162. The link between GALNT14 expression and TIICs was analyzed. Prognostic evaluation was performed using Kaplan-Meier survival analysis and Cox proportional hazards models, with statistical significance set at P < 0.05.Results: GWAS identified 39 SNP loci linked to rs9679162 and associated with postoperative prognosis. In the validation cohort, 10 SNPs were selected and categorized into four groups. Eight SNPs showed strong LD with rs9679162 and were significantly associated with recurrence-free survival and metastasis-free survival. The predictive performance of the combined SNP groups surpassed that of rs9679162 alone, with the most effective stratification achieved by combining groups-2+3. Additionally, GALNT14 expression, linked to the identified genotypes, correlated with M2-macrophage abundance within TIICs.Conclusion: An SNP panel in LD with rs9679162, particularly from group-2 (rs62140629, rs4952033, rs56284247) and group-3 (rs9679162, rs6752303), serves as a prognostic marker for HCC. GALNT14 expression was associated with M2-macrophages, suggesting an immune-regulatory mechanism.Keywords: hepatocellular carcinoma, genetic biomarker, SNP panel, personalized medicine, tumor-infiltrating macrophage |
