3’UTR variants in DEFA5 gene associated with Immunoglobulin A nephropathy susceptibility in the Chinese Han population - Supplementary Table 1

Aim: To evaluate the association between single-nucleotide polymorphisms in the 3? untranslated region of the DEFA5 gene and IgA nephropathy (IgAN) risk, the authors performed an association study in the Chinese Han population. Materials & methods: The authors recruited 426 IgAN patients and 498 controls. The MassARRAY platform (Agena Bioscience, Inc., CA, USA) was used to genotype single-nucleotide polymorphisms in DEFA5. Odds ratios and 95% CIs were calculated through logistic regression analysis. Results: The authors observed that rs12716641 significantly reduced IgAN risk in the allele (odds ratio: 0.77; p = 0.026) and genotype (odds ratio: 0.75; p = 0.039) models. Stratification analysis revealed that several genotypes of rs12716641 played a protective role against IgAN. Conclusion: The authors’ results revealed that single-nucleotide polymorphisms in the 3? untranslated region of DEFA5 were associated with IgAN risk.
