Osteopontin (OPN) genetic variants are linked to kidney stone risk. The OPN rs11439060 polymorphism may serve as a biomarker for identifying individuals at higher risk of developing nephrolithiasis.
Area of Science:
- Genetics
- Nephrology
- Biomarkers
Background:
- Osteopontin (OPN) plays a role in urolithiasis.
- Limited research exists on the association between OPN genetic variants and urolithiasis risk.
Purpose of the Study:
- To investigate the association between OPN gene polymorphisms and nephrolithiasis risk.
- To identify potential genetic biomarkers for high-risk nephrolithiasis patients.
Main Methods:
- Genotyping of three OPN single-nucleotide polymorphisms (SNPs): rs28357094, rs11439060, and rs11730582.
- Case-control study involving 230 nephrolithiasis patients and 250 healthy controls.
- Assessment of associations between SNPs and nephrolithiasis risk in various genetic models and stratified analyses.
Main Results:
- No significant differences in genotype or allele frequencies were found for OPN rs28357094 and rs11730582.
- Carriers of OPN rs11439060 insertion types were more prevalent in urolithiasis patients (OR, 1.55; 95% CI, 1.08-2.22).
- Increased risk associated with rs11439060 was more pronounced in younger subjects, females, overweight individuals, normotensive individuals, those with abnormal blood sugar, smokers, and ever-drinkers.
Conclusions:
- The OPN rs11439060 polymorphism may serve as a genetic biomarker for detecting high-risk nephrolithiasis patients.
- Further research is warranted to validate these findings and explore the underlying mechanisms.
