Abstract
Well-differentiated thyroid cancer accounts for 95% of thyroid malignancies. In contrast to medullary thyroid carcinoma, in which about 25% are familial, only 5% of follicular cell-derived thyroid carcinomas are a component of a familial cancer syndrome. The familial follicular cell-derived tumors o...

Abstract
In recent years, the clinical validation of molecular targeted therapies inhibiting the action of pathogenic tyrosine kinase (TK) has been one of the most exciting developments in cancer research. In this context, medullary thyroid carcinoma (MTC) represents a promising model. It is...

Abstract
Many hematologic malignancies have an underlying heritable component. Although not as well characterized as the acquired genetic abnormalities that define important prognostic and therapeutic subgroups of myeloid and lymphoid neoplasms, investigations are beginning to unravel the role of germline ge...

Abstract
25-30% of families fulfilling the criteria for hereditary diffuse gastric cancer have germline mutations of the CDH1 (E-cadherin) gene. In light of new data and advancement of technologies, a multidisciplinary workshop was convened to discuss genetic testing, surgery, endoscopy and p...

Abstract
The British Society of Gastroenterology (BSG) and the Association of Coloproctology for Great Britain and Ireland (ACPGBI) commissioned this update of the 2002 guidance. The aim, as before, is to provide guidance on the appropriateness, method and frequency of screening for people at moderate and hi...

Abstract
Geneticists estimate that 5% to 10% of all cancers diagnosed in the pediatric age range occur in children born with a genetic mutation that directly increases their lifetime risk for neoplasia. However, despite the fact that only a fraction of cancers in children occur as a result of an identified i...

Abstract
We report the clinical and genetic findings in a 23-year-old woman with hyperparathyroidism-jaw tumor syndrome (HPT-JT). The patient had a family history of primary hyperparathyroidism (PHPT) and uterine fibroma in her mother. The patient presented muscle weakness. The diagnosis of PHPT was confirme...

We also briefly describe the genetic basis of three other inherited states predisposing individuals to endocrine tumors, namely Carney's syndrome, hyperparathyroidism type 2 (HRPT2) and familial isolated pituitary adenoma (FIPA), which are related to inactivating mutations in the PRKAR1-alpha, HRPT2...

Abstract
Von Hippel-Lindau syndrome (VHLS) is an autosomal dominant familial cancer syndrome arising from germ-line inactivation of the VHL gene on the short arm of chromosome 3. VHLS manifests in a myriad of hyper-vascular tumors of both benign and malignant nature. Incidence of VHLS is roughly 1 in 36,000...

Abstract
Pituitary adenomas were previously thought to be rare. However, a recent cross-sectional study conducted in Liège, Belgium, showed that clinically apparent pituitary adenomas were present in about 1 in 1000 inhabitants, which is 4 to 5 times the previously reported prevalence. Pituitary adenomas ar...

Abstract
Genetic testing for adult-onset diseases is now available. One such test is for the mutations present in the BRCA gene that result in a significantly higher risk for the development of breast cancer or ovarian cancer. Women who have one of these mutations face difficult choices in terms of increased...

Ten per cent of all breast cancer cases have a strong hereditary component in which half carry a deleterious mutation in the high penetrance genes BRCA1 or BRCA2. These genes confer a lifetime risk of 60-80% for breast cancer and 20-40% for ovarian cancer. Since the identification of these genes in...

Phaeochromocytoma is a rare clinical entity in children. Contrary to traditional teaching, which suggested that 10% of phaeochromocytomas are "familial", a germline mutation has been identified in up to 59% (27/48) of apparently sporadic phaeochromocytomas presenting at 18 years or younger and in 70...

Abstract
The BHD mutation detection rate was 88% (51/58). Of the 23 different germline mutations identified, 13 were novel consisting of: four splice site, three deletions, two insertions, two nonsense, one deletion/insertion, and one missense mutation. We report the first germline missense mutation in BHD c...

An estimated 5% of all non-medullary thyroid cancers are hereditary. If three or more first-degree relatives are affected, there is a greater than 94% chance that these cases are hereditary non-medullary thyroid cancer (HNMTC). Although, the susceptibility gene(s) for HNMTC has not been identified,...
