Abstract

Loss of function mutations in the fumarate hydratase (fumarase, FH) gene were recently identified as the cause for dominantly inherited uterine and cutaneous leiomyomas and renal cell cancer. To further evaluate the role of FH in tumorigenesis, we screened FH mutations from tumor types seen in hereditary leiomyomatosis and renal cell cancer mutation carriers - 41 uterine and 10 cutaneous leiomyomas, 52 renal cell carcinomas, 53 sarcomas, 29 prostate carcinomas, and 15 lobular breast carcinomas. Few mutations were detected. Biallelic inactivation of FH was found in one uterine leiomyosarcoma, one cutaneous Ieiomyoma, and one soft tissue sarcoma. Whereas the two former lesions were shown to originate from a germ-line mutation, the soft tissue sarcoma is to our knowledge the first example of purely somatic inactivation of FH in tumors.
