Background: Genetic variants are identified in a small proportion (~10%) of patients with Congenital Hypopituitarism (CH), with variable associated phenotypes. We aimed to phenotypically characterise a large cohort of patients with genetically proven CH.Patients and methods: 1684 CH patients were screened (Sanger or whole exome sequencing) over a 20-year period (1998-2018) for mutations in genes regulating pitui...

Objectives: We describe 5 pedigrees with a novel phenotype including GHD associated with primary ovarian insufficiency (POI) and investigate the underlying molecular basis.Patients and Methods: 6 Turkish patients (5F, 1M) born to 5 consanguineous pedigrees with severe GHD were identified. All females had POI; the male had normal puberty. All had severe postnatal growth retardation (height -4.4 to -8.9 SDS at presentation...

Background: Central diabetes insipidus (CDI) in the neonatal age is usually a result of intracranial insult, either congenital or acquired. Familial CDI is usually an autosomal dominant disorder, presenting later in childhood (1-6 y) with polyuria and mostly caused by mutations in the Neurophysin II moiety of the AVP-NPII prohormone gene; these interfere with prohormone processing leading to gradual destruction of AVP secreting cells and result in arginine vas...

Background: Craniopharyngiomas (CPs) are benign brain tumours that intimately involve pituitary and, often, hypothalamus. Here, primary clinical conundrum is choosing between gross total resection and preserving endocrine functions. Robust predictors of recurrence are much needed, but require a deeper understanding of the molecular basis of CPs. Multiple studies show that CTNNB1 (β-catenin) somatic mutations drive the adamantinomatous subtype ...

Patients and Methods: We analyzed 135 primary operated craniopharyngioma (CP) patients and 75 CP patients, received radiotherapy/radiosurgery in 2005-2012. Neurologic, endocrine, visual functions, quality of life (QofL) and neuroimaging data before and after treatment were assessed.Patients were divided in 2 groups according to CP location: 48,5% endosellar (ESCP), and 51,5% suprasellar (SSCP). Surgical treatment included tumor e...

Context: Puberty timing is highly heritable. Recent genome-wide association studies, comparing timing of menarche in girls to timing of voice-break and facial hair in boys, revealed a largely overlapping genetic architecture of female and male pubertal timing. However, it is also known that genetic heterogeneity between sexes exists for some loci.Objectives: We hypothesized that self-reported relative parental pubertal t...
