Hamartomatous Polyposis Syndromes: Management and Surveillance Strategies
Introduction: Hamartomatous Polyposis Syndromes (HPS) are a rare group of dominant autosomal inheritance, which is characterized by the development of hamartomatous polyps in the gastrointestinal tract. This syndrome included Juvenile Polyposis syndrome (JPS), Peutz-Jeghers syndrome (PJS), and PTEN Hamartoma Tumour Syndrome (PHTS). PTEN Hamartoma Tumour Syndrome (PHTS) itself includes Cowden ...
متن کاملPTEN Gene: A Model for Genetic Diseases in Dermatology
PTEN gene is considered one of the most mutated tumor suppressor genes in human cancer, and it's likely to become the first one in the near future. Since 1997, its involvement in tumor suppression has smoothly increased, up to the current importance. Germline mutations of PTEN cause the PTEN hamartoma tumor syndrome (PHTS), which include the past-called Cowden, Bannayan-Riley-Ruvalcaba, Proteus...
متن کاملExpression of the PTEN tumour suppressor protein during human development.
The tumour suppressor gene PTEN, localized to 10q23.3, is the susceptibility gene for Cowden syndrome (CS) and Bannayan-Riley-Ruvalcaba (BRR) syndrome, two hamartoma syndromes with an increased risk of breast and thyroid tumours. Somatic mutations have been found in a variety of human tumours. Functional studies have revealed that PTEN plays a fundamental role in cellular growth, death, adhesio...
متن کاملThe microbiome in PTEN hamartoma tumor syndrome
Germline PTEN mutations defining PTEN hamartoma tumor syndrome (PHTS) confer heritable predisposition to breast, endometrial, thyroid and other cancers with known age-related risks, but it remains impossible to predict if any individual will develop cancer. In the general population, gut microbial dysbiosis has been linked to cancer, yet is unclear whether these are associated in PHTS patients....
متن کاملPTEN mosaicism with features of Cowden syndrome.
We present the first known case of somatic PTEN mosaicism causing features of Cowden syndrome (CS) and inheritance in the subsequent generation. A 20-year-old woman presented for genetics evaluation with multiple ganglioneuromas of the colon. On examination, she was found to have a thyroid goiter, macrocephaly, and tongue papules, all suggestive of CS. However, her reported family history was n...
متن کاملCowden syndrome-related mutations in PTEN associate with enhanced proteasome activity.
Germline mutations in PTEN have been described in a spectrum of syndromes that are collectively known as PTEN hamartoma tumor syndrome (PHTS). In addition to being mutated in the germline in PHTS, somatic loss-of-function PTEN mutations are seen in a wide range of sporadic human tumors. Here, we show evidence of upregulated proteasome activity in PHTS-derived lymphoblasts, Pten knock-in mice an...
