SEMA3G and neoplasm: A prognostic index for tumor samples could be calculated by the formula: IRGPI = (HTN3 expression * 0.096) + (CTSG expression * −0.152) + (MAPT expression * 0.122) + (CCL28 expression * −0.094) + (PTX3 expression * 0.138) + (SEMA3G expression * −0.140) + (USP2 expression * 0.107).
