WNT3A and periapical periodontitis: Analysis of single SNP associations showed a trend linking “WNT3 rs9890413 genotypes” under a dominant model, along with “an allelic association for WNT3A rs1745420.” Additionally, haplotypes composed of “WNT3, WNT9B, and WNT3A alleles” were appreciably associated with apical periodontitis [61].
