PTEN hamartoma tumor syndrome: an overview

Open access
Hobert, Judith A., Eng, Charis·2009·Genetics in Medicine

Abstract

PTEN hamartoma tumor syndrome (PHTS) encompasses four major clinically distinct syndromes associated with germline mutations in the tumor suppressor PTEN. These allelic disorders, Cowden syndrome, Bannayan-Riley-Ruvalcaba syndrome, Proteus syndrome, and Proteus-like syndrome are associated with unregulated cellular proliferation leading to the formation of hamartomas. Thus far, an increased risk of malignancy has only been documented in Cowden syndrome; however, current recommendations advise that all individuals with PTEN hamartoma tumor syndrome follow the cancer surveillance strategies suggested for Cowden syndrome until further data indicate otherwise. Because any individual phenotypic feature of Cowden syndrome and Bannayan-Riley-Ruvalcaba syndrome are frequently present in the general population, many individuals often go undiagnosed and consequently do not benefit from available cancer surveillance strategies. Therefore, it is critical for clinicians to recognize the phenotypic features associated with these syndromes to accurately diagnose and provide preventative care. This overview details the clinical description of the PTEN hamartoma tumor syndrome and associated disorders, their diagnosis and molecular/genetic testing, as well as differential diagnosis for assessment of other hamartoma-associated syndromes.

  • PTEN is an important tumour suppressor gene mutated in 6% of colorectal cancers.

    “It is an important tumour suppressor gene mutated in 6% of colorectal cancers (CRCs), and germline variants in PTEN are causative of PTEN hamartoma tumour syndrome (Hobert and Eng, 2009; Cerami et al., 2012).”

    From Efficient genetic editing of human intestinal organoids using ribonucleoprotein-based CRISPR (2023) · cites this paper as Hobert and Eng, 2009

    The overview identifies PTEN as a tumor suppressor and says germline PTEN mutations cause Cowden syndrome, a PTEN hamartoma tumor syndrome (opening section; page not specified). It does not report that PTEN is mutated in 6% of colorectal cancers; searches for that figure and colorectal cancer mutation frequency found no supporting passage. (LLM, conf=0.88)

  • Germline variants in PTEN are causative of PTEN hamartoma tumour syndrome.

    “It is an important tumour suppressor gene mutated in 6% of colorectal cancers (CRCs), and germline variants in PTEN are causative of PTEN hamartoma tumour syndrome (Hobert and Eng, 2009; Cerami et al., 2012).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
