PTEN (phosphatase and tensin homolog) is a gene that encodes for phosphatidylinositol 3,4,5-trisphosphate 3-phosphatase and dual-specificity protein phosphatase PTEN. This protein is a lipid/protein phosphatase that plays a role in multiple cell processes, including growth, proliferation, survival, and maintenance of genomic integrity. PTEN acts as a tumor suppressor by negatively regulating the PI3K/AKT signaling pathway. Somatic mutations of PTEN occur in multiple malignancies, including glioma, melanoma, prostate, endometrial, breast, ovarian, renal, and lung cancers. Germline mutations of PTEN lead to inherited hamartoma and Cowden syndrome (for reviews see PMID: 18767981 and PMID: 17827710).

PTEN is altered in 7.17% of all cancers with uterine corpus neoplasm, malignant glioma, breast carcinoma, colorectal adenocarcinoma, and prostate cancer having the greatest prevalence of alterations [3].

PTEN GENIE Cases - Top Diseases

The most common alterations in PTEN are PTEN Mutation (7.62%), PTEN Mutation (germline) (7.62%), PTEN Mutation (somatic) (7.62%), PTEN Nonsense (2.23%), and PTEN Frameshift (2.22%) [3].
