Interestingly, two loss-of-connectivity pairs for gastric cancer (SPINT1 and GMDS, and GMDS and TNRC18) were observed among the five gain-of-connectivity pairs for Parkinson’s disease, implying a possible opposite direction of change at the gene-to-gene interaction level for Parkinson’s disease and gastric cancer. This evidence concerns the gene TNRC18 and Parkinson disease.
