Results

A total of 17 candidate single nucleotide polymorphisms were assessed in 185 patients with RA and chronic periodontitis (CP), 149 patients with type 2 DM and CP, 251 patients with CP, and 130 systemically and periodontally healthy controls from a cohort of Japanese adults. The results indicated that the potassium voltage-gated channel KQT-like subfamily, member 1 (KCNQ1) rs2237892 and the peptidylarginine deiminase type 4 (PADI4)_104 rs1748033 polymorphisms were significantly associated with the comorbidity of RA and CP. Additionally, a trend toward increase was shown in the serum levels of anti-cyclic citrullinated peptide immunoglobulin G in the patients with RA and CP as compared to those with RA only. These results suggest that the KCNQ1 and possibly the PADI4_104 may constitute a shared risk gene for RA and CP in Japanese adults.
