TP53 (tumor protein p53 (Li-Fraumeni syndrome))
393 amino acids; 53 kDa protein; numerous post translational modifications: phosphorylation, acetylation, ubiquitination, sumoylation, neddylation. Contains from N-term to C-term, a transactivation domain (1-42), a Proline rich domain (63-97), a specific DNA binding domain (102-292), 3 nuclear localization signals (305-322), a tetramerization domain that include a nuclear export signal (325-355...
متن کاملGermline TP53 mutations and Li-Fraumeni syndrome.
There are now reports of nearly 250 independent germline TP53 (p53) mutations in over 100 publications. Such mutations are typically associated with Li-Fraumeni or Li-Fraumeni-like syndrome, although many have been identified in cohorts of patients with tumors considered to be typical of LFS. In general, the spectrum of mutations that has been detected in the germline reflects that found in tum...
متن کاملMalignant triton tumor in a patient with Li-Fraumeni syndrome and a novel TP53 mutation.
We report a 3-year-old boy with a malignant triton tumor (MTT) involving the left masticator space with local invasion and regional lymph node metastasis. Family history and detection of a novel germline TP53 mutation confirmed his diagnosis of Li Fraumeni syndrome (LFS). MTT has not been previously described in association with LFS. This case along with a comprehensive review of the literature...
متن کاملLi-fraumeni syndrome.
Li-Fraumeni syndrome (LFS) is a classic cancer predisposition disorder that is commonly associated with germline mutations of the p53 tumor suppressor gene. Examination of the wide spectrum of adult-onset and childhood cancers and the distribution of p53 mutations has led to a greater understanding of cancer genotype-phenotype correlations. However, the complex LFS phenotype is not readily expl...
متن کاملp53 therapy in a patient with Li-Fraumeni syndrome.
Li-Fraumeni syndrome is an autosomal dominant disorder that greatly increases the risk of developing multiple types of cancer. The majority of Li-Fraumeni syndrome families contain germ-line mutations in the p53 tumor suppressor gene. We describe treatment of a refractory, progressive Li-Fraumeni syndrome embryonal carcinoma with a p53 therapy (Advexin) targeted to the underlying molecular defe...
