Background: The aetiology of congenital hypopituitarism (CH) is unknown in the majority of patients. In our cohort of 200 cases, it was possible to establish the genetic cause in only 13 patients (6.5%). Copy number variants (CNVs) have been implicated as the cause of genetic syndromes with previously unknown aetiology.Objective: To study the presence of CNVs and its relevance in patients with CH of unknown cause associated with complex phenotypes.<p...

Background: Genetic causes of central precocious puberty (CPP) has been increasingly recognized, extending our knowledge of the triggering factors of human pubertal timing. Distinct etiologies remain to be elucidated in sporadic and familial cases. Methyl-CpG-binding protein 2 (MECP2) is a chromatin-associated protein that can activate or repress gene transcription, playing a role in neuronal maturation. It is encoded by MECP2 gene located at chromoso...
