AMELX and dental caries: Sharifi et al. [13] in a meta-analysis study found that ENAM rs3796704 polymorphism, especially in the Caucasus ethnic group and in studies with caries-free individuals as a control group, had a higher risk of caries, but they found no association between polymorphisms LTF rs1126478, ENAM (rs1264848 and rs3796703), and AMELX (rs946252, rs17878486, and rs2106416) and susceptibility to dental caries.
