A possible correlation of SNPs in the THBS2 sequence with the binding affinity of miR-4677-5p might be a perfect method to find more accurate information about the reasons for the high or low expression of THBS2. Since the result of our survival analysis was not significant, we highly recommend that the possible correlation of mentioned RNAs with the survival rate of GC patients be evaluated through a bigger sample size. The gene discussed is THBS2; the disease is gastric cancer.
