Peutz-Jeghers disease: most, but not all, families are compatible with linkage to 19p13.3.
A locus for Peutz-Jeghers syndrome (PJS) was recently mapped to chromosome 19p13.3. Each of 12 families studied was compatible with linkage to the marker D19S886. We have analysed 20 further families and found that the majority of these are consistent with a PJS gene on 19p13.3. Three families were, however, unlinked to 19p13.3 and none of the available PJS polyps from these families showed all...
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...
متن کاملPeutz-Jeghers syndrome
Introduction Peutz-Jeghers syndrome (PJS) is characterized by: (i) autosomal dominant inheritance; (ii) cutaneous pigmentation; (iii) gastro-intestinal polyposis. In all, more than 300 cases have been described with a world-wide distribution and no racial predilection. In 1921 Peutz described 7 cases of multiple intestinal polyps associated with melanin spots on the lips, buccal mucosa and digi...
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 کامل[Peutz-Jeghers syndrome].
Peutz-Jeghers syndrome is an inherited disorder which usually debuts during childhood. It is characterized by mucocutaneous pigmentation and hamartomatous polyps in the gastrointestinal tract. Numerous reports indicate a high incidence of gastrointestinal and extraintestinal cancer in these patients, their appearance at a young age, as well as its association with ovarian and testicular tumors....
