Introduction: In line with the association of prostaglandin-endoperoxide synthase 2 (PTGS2) and defensin beta 1 (DEFB1) single nucleotide polymorphisms (SNPs) with periodontitis among the Chinese and European populations, the current study was aimed to assess the same association among the Malays in Malaysia. Methods: Blood samples of individuals with periodontitis (PD) (n=72) and periodontally healthy (PH) (n=62) donors were obtained from Malaysian Periodontal Database and rs20417, rs689466,) and one DEFB1 SNP (rs1047031) using Taqman SNP genotyping assays. Notably, rs20417 and rs689466 were located in the promoter region while rs5275 and rs1047031 were located in the 3' untranslated region of the transcript. Association between the SNPs and PD were then analyzed using genotypic association analysis (additive, dominant and recessive models). Results: The allelic frequency for the rs689466-G was higher in PD group (35.2%) compared that in PH group (29.0%). However, the association of rs689466-G and other SNPs with PD was not statistically significant (at 95% CI). No associations were observed for genotypic associations between the PTGS2 and DEFB1 SNPs with PD susceptibility. Conclusions: PTGS2 (rs5275, rs20417, and rs689466) and DEFB1 (rs1047031) polymorphism was not associated with PD in Malays, unlike the Chinese, Taiwanese & European population. This suggests that other causal variants might be involved in the development and progression of PD among Malays.
