A germ-line mutation of hMSH6 (also called GTBP) was found in a hereditary nonpolyposis colorectal cancer (HNPCC)-like patient in whom germ-line mutations of hMSH2, hMSH3, or hMLH1 had not been detected. The patient had rectal cancer and two colon adenomas at 62 years of age and a weak family history of gastrointestinal tumors, indicating atypical HNPCC. Somatic mutations of hMSH6 were observed...

INTRODUCTION In 2008, colorectal cancer represented the third most commonly diagnosed tumor in Spain, and the second tumor with more deaths. Despite the new potential biomarkers in colorectal cancer, there are many challenges that need to be overcome, resulting in a need for the standardization of its determinations. DISCUSSION The continuous advance in tumor disease knowledge makes this revi...

Background Causative genetic variants have to date been identified for only a small proportion of familial colorectal cancer (CRC). While conditions such as Familial Adenomatous Polyposis (FAP) and Lynch Syndrome (Hereditary Nonpolyposis Colorectal Cancer, HNPCC) are caused by well defined genetic defects, the search for variants underlying the remainder of familial CRC is plagued by genetic he...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 colorectal cancer is classified in to three forms: sporadic (70-75%), familial (20-25%) and hereditary (5-10%). hereditary colorectal cancer syndromes classified into two different subtypes: polyposis and non polyposis. familial adenomatous polyposis (fap; omim #175100) is the most common polyposis syndrome, account for <1...

The genetic basis of sporadic colorectal cancer has illuminated our knowledge of human cancer genetics. This has been facilitated and catalyzed by an appreciation and deep understanding of the forms of colorectal cancer that harbor an inherited predisposition, including familial adenomatous polyposis (FAP), hereditary nonpolyposis colorectal cancer (HNPCC) or Lynch syndrome, the hamartomatous p...
