Association analysis of five SNP variants with gout in the Minnan population in China.

Background/aim: There is a very high prevalence of gout in the Minnan population in China. We aimed to explore the genetic characteristics and genetic mechanisms of gout in the Minnan population by studying the association of 5 single nucleotide polymorphisms (SNPs) with gout.

Materials And Methods: A total of 163 gout patients and 187 normal controls from Minnan were enrolled in this case-control study. SNPs (rs1165205, rs3733591, rs6855911, rs2231142, rs333049) were genotyped by allele-specific polymerase chain reaction (PCR) and analyzed with SPSS 16.0.

Results: Significant association with gout was found for rs2231142 (P < 0.001), consistent with our prior studies. An association between rs1333049 and gout was also found (P = 0.03) in the Minnan population. No association of SNPs rs6855911, rs3733591, and rs1165205 was found with gout in the Minnan population.

Conclusion: Rs1333049 is associated with gout in the Minnan population, although rs2231142 shows an even stronger association with gout. The C allele of rs1333049 and the A allele of rs2231142 might be crucial risk factors for gout.
