Association Between Klotho Gene Polymorphisms and Urolithiasis: A Meta-Analysis.

Former studies have suggested that urolithiasis is related to Klotho gene polymorphisms. The aim of this meta-analysis was to investigate this relationship. Studies on the association between urolithiasis susceptibility and Klotho gene polymorphisms were systematically searched for in databases. Odds ratios and 95% confidence intervals were pooled as the effect size. This meta-analysis incorporated ten articles. Klotho rs1207568 adenine (A) may be related to a decreased urolithiasis risk in Caucasians. The results showed that Klotho rs3752472 may not be related to urolithiasis risk in the Han Asian subgroup. Klotho rs564481 may not be related to urolithiasis risk in Asians or Caucasians, and Klotho rs650439 may not be related to urolithiasis risk in Asians. Key Words: Klotho, Single-nucleotide polymorphism, Urolithiasis, Meta-analysis.
