Somatic activating mutations in BRAF, encoding B-Raf, have been described in tumours and recently craniopharyngiomas. Germline mutations in BRAF and other components of the RAS/MAPK pathway are found in RASopathies, whose features include endocrine deficiencies but not craniopharyngiomas. We report three BRAF mutations (two of which are novel) in four children with congenital hypopituitarism. To demonstrate the functional role of the three variants w...

Germline mutations in BRAF and other components of the RAS/MAPK pathway are found in RASopathies, whose features include short stature and pubertal delay. The underlying mechanism of endocrinopathies in RASopathies has not been fully elucidated. We report four BRAF mutations (two of which are novel) in four children with congenital hypopituitarism and RASopathy features. To demonstrate the functional role of the variants we performed phosphoproteomic analyses...

Introduction: Craniopharyngiomas (CPs) are histologically benign tumours but are clinically associated with significant morbidity and mortality. Recurrence of CPs is known to influence mortality, but apart from the extent of surgical resection, no clinical characteristics have been shown to predict recurrence. Complete resection is difficult due to their infiltrative behaviour and unacceptable morbidity. Thus, predictors of risk of recurrence are needed....
