Cowden syndrome is a rare autosomal dominant familial cancer syndrome with a high risk of breast cancer. The most important clinical features include carcinomas of the breast and thyroid, and hamartomatous polyps of the gastrointestinal tract. There are characteristic mucocutaneous features which allow early recognition of the disease and are generally present before internal malignancies devel...

One case of non-penetrance of the familial adenomatous polyposis (FAP) gene at 59 years of age and late onset of polyps on endoscopy and biopsy in this and two other families is described. Screening protocols should include dental screening as well as indirect ophthalmoscopy and endoscopy to detect minimal manifestations of the gene. In the absence of a specific DNA predictive test, bowel scree...

Familial adenomatous polyposis (FAP) is a hereditary syndrome characterized by the presence of multiple polyps in colon. The main cause disease germline mutation APC gene. Here we report 4 unrelated FAP patients with different large deletions gene detected Multiplex Ligation-dependent Probe Amplification (MLPA) method: deletion exons 7-15, promoters B, A, and 5'-UTR region promoter B (in 2 pati...

The phenotypic expression in familial adenomatous polyposis (FAP) is variable. This study compares the phenotype of 27 patients with an identical 5 base pair (bp) deletion at codon 1309 with a group of 61 matched patients with FAP where knowledge of specific mutations is not available and with seven other different mutations in 24 subjects. Patients with the codon 1309 deletion have significant...

BACKGROUND/AIM The aim of our study was to check how MGMT methylation status together with known factors influenced the risk of colon cancer development. MATERIALS AND METHODS We examined patients with colon polyps. Information concerning gender, age, lifestyle, diet, anthropometry and medical information, including cancer and family history of cancer, was analyzed. Polymorphism variety of MG...

Recently we have isolated the adenomatous polyposis coli (APC) gene which causes familial adenomatous polyposis (FAP), and its germ-line mutations in a substantial number of FAP patients have been identified. On the basis of this information, we compared the location of germ-line mutations in the APC gene in 22 unrelated patients (12 of whom have been reported previously) with the number of col...

Familial Adenomatous Polyposis (FAP) is the most common adenomatous polyposis syndrome, in which patients develop hundreds to thousands of polyps at an early age. The high number significantly increases risk their progression colorectal cancer (CRC). To investigate development and mechanism FAP, we used APC1311 mutant pigs our recent research has revealed that a significant proportion these und...

The first-degree relatives of patients affected by colorectal cancer, who do not belong to familial adenomatous polyposis and hereditary nonpolyposis colorectal cancer families, have a doubled risk of developing tumors of the large intestine. We have previously demonstrated that subjects with a single first-degree relative (SFDR) with colon cancer have a doubled risk for developing colorectal a...

INTRODUCTION Peutz-Jeghers syndrome (PJS) is a rare familial disorder characterised by mucocutaneous pigmentation, gastrointestinal and extragastrointestinal hamartomatous polyps and an increased risk of malignancy. Peutz-Jeghers polyps in the bowel may result in intussusception. This complication usually manifests with abdominal pain and signs of intestinal obstruction. CASE PRESENTATION We ...

The concept of the adenoma-carcinoma sequence, as first espoused by Morson et al. whereby the development of colorectal cancer is dependent on a stepwise progression from adenomatous polyp to carcinoma is well documented. Initial studies of the genetics of inherited colorectal cancer susceptibility concentrated on the inherited colorectal cancer syndromes, such as Familial Adenomatous Polyposis...
