Germline mutations of the LKB1 (STK11) gene in Peutz-Jeghers patients.
Germline mutations of the LKB1 (STK11) serine/threonine kinase gene (chromosome 19p13.3) cause Peutz-Jeghers syndrome, which is characterised by hamartomas of the gastrointestinal tract and typical pigmentation. Peutz-Jeghers syndrome carries an overall risk of cancer that may be up to 20 times that of the general population. Here, we report the results of a screen for germline LKB1 mutations b...
متن کاملLow frequency of somatic mutations in the LKB1/Peutz-Jeghers syndrome gene in sporadic breast cancer.
Germ-line mutations in the LKB1 gene on chromosome 19p are responsible for most cases of the Peutz-Jeghers syndrome, in which intestinal hamartomas are associated with elevated risks of several cancer types, including breast cancer. We have evaluated the role of somatic mutations in LKB1 in breast cancer. Of 40 informative primary breast cancers, 3 showed loss of heterozygosity on chromosome 19...
متن کاملMutations in the STK11 gene in Czech Peutz-Jeghers families
Background: Peutz-Jeghers syndrome (PJS) is an autosomal dominant hereditary disease characterized by mucocutaneous pigmentation and gastrointestinal hamartomatous polyposis. The germline mutations in the serine/threonine kinase 11 (STK11) gene have been shown to be associated with the disease. Individuals with PJS are at increased risk for various neoplasms. Molecular analysis could be helpful...
متن کاملFrequency and spectrum of cancers in the Peutz-Jeghers syndrome.
BACKGROUND Although an increased cancer risk in Peutz-Jeghers syndrome is established, data on the spectrum of tumors associated with the disease and the influence of germ-line STK11/LKB1 (serine/threonine kinase) mutation status are limited. EXPERIMENTAL DESIGN We analyzed the incidence of cancer in 419 individuals with Peutz-Jeghers syndrome, and 297 had documented STK11/LKB1 mutations. R...
متن کاملPeutz-Jeghers families unlinked to STK11/LKB1 gene mutations are highly predisposed to primitive biliary adenocarcinoma.
INTRODUCTION Germline mutations of the STK11/LKB1 tumour suppressor gene (19p13.3) are responsible for Peutz-Jeghers syndrome (PJS), a rare genetic disorder, which is dominantly inherited. In addition to the typical hamartomatous gastrointestinal polyps and perioral pigmented lesions, PJS is also associated with the development of tumours in various sites. No specific follow up has yet been eva...
