Question

Quizplus · Accepted Answer

Li-Fraumeni syndrome is caused by an inherited mutation in the p53 tumor suppressor gene, which normally helps prevent cells from becoming cancerous. When the gene is mutated, it increases the risk of developing various types of cancer, including breast cancer, sarcoma, brain tumors, and others. Mutations in the other genes listed (Hemoglobin beta, Dystrophin, and Phenylalanine hydroxylase) are associated with different genetic disorders and do not cause Li-Fraumeni syndrome.
