Similarly, the association between AP occurrence and smoking in the subjects with GG, GC and CC genotypes for SNP rs10636 in the MT2A gene was not found (OR = 0.9959, p = 0.9998; OR = 1.4999, p = 0.3176; OR = 2.5000, p = 0.3019, respectively). Here, MT2A is linked to alkaline phosphatase measurement.
