FAMILIAL NONMEDULLARY THYROID CANCER (Abstract): Follicular cell-derived thyroid cancer which represents 90-95% of all thyroid malignancies may occur in at least 5% of cases as familial disease. Familial nonmedullary thyroid cancer (FNMTC) is defined as the existence of two or more first degree relatives affected within a family. FNMTC may occur in two situations: pure FNMTC in which FNMTC is t...

In the familial form of papillary thyroid cancer (PTC), two or more members of the same family have to be affected with PTC. Prevalence is around 5% of all PTC. We performed a clinical analysis in 79 relatives of 16 patients of 7 unrelated kindred with the diagnosis of familial papillary thyroid carcinoma (FPTC). The results were compared with a control group. Thyroid palpation and TSH and TPO-...

     Familial adenomatous polyposis (FAP) is a hereditary autosomal dominant cancer syndrome, results from germ line mutation or deletion of the Adenomatous Polyposis Coli (APC) gene on chromosome 5q21. Patients with FAP suffer from multiple polyps mainly at the colorectal region as well as other parts of the gastrointestinal tract, which has propensity to transform into carcinoma. FAP has also...

Common variation on 14q24.1, close to RAD51B, has been associated with breast cancer: rs999737 and rs2588809 with the risk of female breast cancer and rs1314913 with the risk of male breast cancer. The aim of this study was to investigate the role of RAD51B variants in breast cancer predisposition, particularly in the context of familial breast cancer in Finland. We sequenced the coding region ...

A new study found that the ataxia tel-angiectasia mutated (ATM) gene — a gene linked with breast cancer and suspected in many others — may increase the hereditary risk for pancreatic cancer. According to the study, published in the January 2012 Cancer Discovery , knowledge of the presence of the ATM gene could lead to better screening for pancreatic cancer, the fourth-most-common cause of cance...
