Researchers are investigating tumors affecting the hypothalamic-pituitary unit in children and adults aged 2 to 70 years. The study aims to identify genetic factors involved in the development of these pituitary tumors and related disorders, as well as to develop new clinical studies for their recognition and treatment. It also explores the psychological effects of cortisol secretion in children with Cushing disease and seeks to understand inheritance patterns and associations with other family conditions. Participants undergo procedures including tissue specimen collection and MRI scans to study the molecular genetics of tumors and related developmental pathways. This observational protocol serves as a screening and training platform for medical fellows and students and supports the development of future clinical trials focused on diagnosis and therapy of pituitary tumors. During the study, participants provide peripheral blood and tumor tissue samples for molecular genetic testing. Researchers assess cognitive, psychological, and patient-reported health outcomes related to hypercortisolemia and adrenal insufficiency. The study also monitors clinical and genetic features of pituitary tumors and collects data on mental and social well-being. Participation involves ongoing assessments and follow-up to support future research and clinical care improvements.
