Indeed, we found that, after PRDM9, ZFPM2/FOG2 was the most mutated PRDM gene with pan-cancer frequencies of protein-affecting mutations higher than 1%; specifically, we detected mutation frequencies higher than 5% in patients with skin cutaneous melanoma, lung tumors, uterine carcinosarcoma, esophageal carcinoma, and stomach and rectum adenocarcinomas [45]. Here, ZFPM2 is linked to cancer.
