[Correlation between single nucleotide polymorphism and periodontitis susceptibility in Shanghai Chinese patients].

PURPOSE: To investigate the correlation between 12 single nucleotide polymorphisms (SNPs) from 7 genes and periodontitis of susceptibility in Shanghai Chinese patients.

METHODS

Genotypes of randomly grouped 50 health control subjects and 48 patients with chronic periodontitis were genotyped by MALDI-TOF MS detection system. A questionnaire, medical history, family history, signs, laboratory tests, treatment, follow-up information were collected. Statistical analysis of Chi-square test was performed using SPSS13.0 software package.

RESULTS

In the screening of the 12 target SNPs,the GG genotype of rs2891168 correlated significantly with periodontitis, OR=3.071(95%CI:1.018-9.260,P=0.046).

CONCLUSION

The GG genotype of rs2891168 may correlate significantly with periodontitis of Shanghai Chinese patients and further studies are needed to verify this finding.
