Whereas, in erythrocytes of non-smoking (p < 0.0001 for all genotypes) and smoking (p = 0.0225, p = 0.0304, and p = 0.0278, respectively) AP patients, SOD2 was significantly higher in comparison with healthy subjects with corresponding genotypes (Figure S2c,d). The gene discussed is SOD2; the disease is alkaline phosphatase measurement.
