Interestingly, a genetic study on CGAS of the Korean periodontitis has focused upon ten periodontitis genes (TENM2, LDLRAD4, SLC9C2, RASGRP4, MFSD1, IL4, NMUR2, GPR141, GLK, and A2BP1) identified as the potential candidate genes with genetic risk factors (see Table 1) (Hong et al. 2015). This evidence concerns the gene RBFOX1 and periodontitis.
