Another laboratory reported a genetic study of patients with low-grade serous ovarian carcinoma (LGSOC) for mutation and copy-number variation by whole-exome sequencing, which identified 11% (8/71 cases) of patients with an MACF1 mutation, and concluded that MACF1 could be a novel driver gene for LGSOC [43]. The gene discussed is MACF1; the disease is ovarian serous carcinoma.
