CDH23 expression was positively interacted with LCNL1, CLCN7, GPR153, SLC27A1, CDK18, etc. Otherwise CDH23 expression was negatively related with DDX52, TOP2A, PTPDC1, etc. Further we selected the significantly correlated genes (cor≥0.5) of CDH23 to conduct prognosis analysis in DLBCL via GEPIA database. Here, PTPDC1 is linked to diffuse large B-cell lymphoma.
