This is consistent with our expression analysis result which showed that the change of rs8040855C to G increased the expression of CSPG4P12. We also addressed the expression of CSPG4P12 and its association with genetic polymorphisms in esophageal cancer using the online ncRNA-eQTL database due to the unavailability of direct tissue samples. This evidence concerns the gene CSPG4P12 and esophageal cancer.
