The only recurrent driver mutation was TP53, which was shared between HGSOC primary and metastatic tumours, observed in four patients (OVA_003, OVA_047, OVA_048 and OVA_378) as clonal, except for one case (OVA_003) that became subclonal in the metastasis. The gene discussed is TP53; the disease is metastatic neoplasm.
