This can result in a lifelong tumor predisposition in patients. Often, the syndrome is diagnosed in early childhood because of macrocephaly, dermatological findings, or development delay. Since the correlation between phenotype and genotype is weak, and the penetrance is age-dependent, this poses the question of the appropriate timing of potentially invasive and burdensome examinations for early cancer detection. Case: The present report describes an infant with cleft palate associated with PHTS, a rare occurrence, though the initial report of Cowden syndrome already pointed to oromaxillofacial abnormalities. The recent pediatric literature is reviewed to assess which clinical symptoms should raise suspicion of PHTS and may then lead to early genetic counseling. Conclusion: Since the amount of prospective data remains limited, and the estimation of tumor risk during infancy and adulthood is very difficult, we advocate for early and broad genetic testing in suspected cases, to gain more insights into this rare disease and allow for better counseling for patients and their families.<\/jats:p>","DOI":"10.3390\/clinpract15010022","type":"journal-article","created":{"date-parts":[[2025,1,20]],"date-time":"2025-01-20T04:04:12Z","timestamp":1737345852000},"page":"22","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Newborn with Cleft Palate Associated with PTEN Hamartoma Tumor Syndrome"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2963-4344","authenticated-orcid":false,"given":"Ulf","family":"Nestler","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University Hospital, 04103 Leipzig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Gr\u00e4fe","sequence":"additional","affiliation":[{"name":"Institute for Pediatric Radiology, University Hospital, 04103 Leipzig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1361-7766","authenticated-orcid":false,"given":"Vincent","family":"Strehlow","sequence":"additional","affiliation":[{"name":"Institute of Human Genetics, University of Leipzig Medical Center, 04103 Leipzig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8285-9155","authenticated-orcid":false,"given":"Robin-Tobias","family":"Jauss","sequence":"additional","affiliation":[{"name":"Institute of Human Genetics, University of Leipzig Medical Center, 04103 Leipzig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9959-2306","authenticated-orcid":false,"given":"Andreas","family":"Merkenschlager","sequence":"additional","affiliation":[{"name":"Division of Neuropediatrics, University Hospital, 04103 Leipzig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Annika","family":"Sch\u00f6nfeld","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, University Hospital, 04103 Leipzig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Florian","family":"Wilhelmy","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Hospital, 04103 Leipzig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e29656","DOI":"10.1002\/pbc.29656","article-title":"Neuroblastoma and cutaneous angiosarcoma in a child with PTEN hamartoma tumor syndrome","volume":"69","author":"Leibowitz","year":"2022","journal-title":"Pediatr.
