PTEN Gene Mutations (Cowden Syndrome): Risks & Options
6 天之前 · Inherited mutations in PTEN cause PTEN Hamartoma Tumor Syndrome (PHTS). There are two conditions that may be associated with PHTS, Cowden syndrome and Bannayan-Riley-Ruvalcaba syndrome. What are the cancer risks for people with a PTEN mutation?

2011年3月24日 · PTEN hamartoma tumour syndrome (PHTS) is a group of syndromes characterized by benign growths and a high risk for cancers of the breast, endometrium and thyroid. Cowden syndrome is...
PTEN at a glance - PMC
In addition to cancer-associated somatic mutations, PTEN is often mutated in tumor-prone germline diseases. Genetic studies in mice have unambiguously demonstrated that PTEN is a potent tumor suppressor in almost all organs. Tissue-specific Pten-knockout mice develop tumors in numerous organs (Knobbe et al., 2008; Suzuki et al., 2008).

Cancer Risk Associated With PTEN Pathogenic Variants Identified …
2023年1月12日 · We identified a significant female breast cancer OR of 7.88 (95% CI, 5.57 to 11.16; P = 2.3 × 10 −31), which is consistent with previous reports in HBOC cohorts 22,30 and consistent in direction with PTEN-associated disease cohorts albeit smaller in size likely because of overestimation of risk on the basis of methodology in these ...
Abstract | PTEN is a potent tumour suppressor, and its loss of function is frequently observed in both heritable and sporadic cancers. PTEN has phosphatase- dependent and phosphatase- independent (scaffold) activities in the cell and governs a variety of biological processes, including
