Furthermore, we demonstrated that the low methylation levels of cg sites (cg07581146 and cg19922137) of SYT14 were correlated with an unfavorable PFS (P = 0.041 and P = 0.010) (Figure 7(h) and 7(i)), whereas other methylation cg sites (cg02795029, cg04932544, cg15149095, cg15389528, cg25371503, and cg26158959) were not correlated with a prognostic value for GC patients (P = 0.112, P = 0.139, P = 0.635, P = 0.059, P = 0.205, and P = 0.061, respectively) (Figure S7G, S7H, S7I, S7J, S7K, and S7L). Here, SYT14 is linked to gastric cancer.
