Several significant markers were mapped within two genes: PPFIBP2 and OLFML1. PPFIBP2 encodes protein-tyrosine phosphatase-interacting protein, which is differentially expressed in endometrial cancer [21] and is also involved in tumour cell migration and invasiveness of extracellular signal-regulated kinase depleted cells [22]. The gene discussed is OLFML1; the disease is endometrial cancer.
