Brief Summary:
This is an observational study in pediatric patientis carryng PTEN pathogenic variants aimed to define oncological risk in children and provide a deeper insight of the clinical course, establishing an updated follow-up protocol.
Detailed Description:
PTEN is a tumor suppressor gene that was first linked to cancer predisposition syndromes but, in the following years, its phenotypic spectrum has been in continuous evolution and expansion, and nowadays we know that pathogenic variants n this gene may also be found in children presenting with Autism Spectrum Disorder (ASD), and/or DD and macrocephaly, or also with macrocephaly alone. Thus, the term PTEN Hamartoma Tumor Syndrome (PTHS) is now used when referring to PTEN-related conditions.
Nowadays, there is no recognized standard protocol for pediatric follow-up. The screening in mostly single-Centre-based and generally not performed in infancy, with large variability in protocols and timing.
The penetrance, which was previously believed to follow an age-related pattern, nowadays seems rather to be age-specific, as children mainly present macrocephaly and neuropsychiatric problems (DD/ASD), while adults are diagnosed mostly because of gastrointestinal malignancies, breast cancer, thyroid carcinoma or other tumors. However, it is not always true that adult symptoms never occur in PTHS children and, conversely, pediatric signs may also persist through adulthood.
The present study aims to collect PTEN mutated patients and their relatives diagnosed in Italy and followed in different Centers, offering a large pediatric cohort with a full clinical description and trying to provide a deeper insight of the clinical course and oncological manifestations of PTEN-related syndrome; we would like to establish an updated follow-up protocol in order to address all the possible clinical needs of these children.
