Mondo Description Li-Fraumeni syndrome (LFS) is a rare cancer predisposition syndrome characterized by the early-onset of multiple primary cancers such as breast cancer, soft tissue and bone sarcomas, brain tumors and adrenal cortical carcinoma (ACC).
Uniprot Description An autosomal dominant familial cancer syndrome that in its classic form is defined by the existence of a proband affected by a sarcoma before 45 years with a first degree relative affected by any tumor before 45 years and another first degree relative with any tumor before 45 years or a sarcoma at any age. Other clinical definitions for LFS have been proposed and called Li-Fraumeni like syndrome (LFL). In these families affected relatives develop a diverse set of malignancies at unusually early ages. Four types of cancers account for 80% of tumors occurring in TP53 germline mutation carriers: breast cancers, soft tissue and bone sarcomas, brain tumors (astrocytomas) and adrenocortical carcinomas. Less frequent tumors include choroid plexus carcinoma or papilloma before the age of 15, rhabdomyosarcoma before the age of 5, leukemia, Wilms tumor, malignant phyllodes tumor, colorectal and gastric cancers.
Disease Ontology Description An autosomal dominant disease characterized by increases risk of developing several types of cancer, including breast cancer, osteosarcomata and soft tissue sarcomata.
