Introduction: Variegated mosaic aneuploidy syndrome (MVA) is a rare autosomal recessive disease characterized by a variable percentage of chromosomal gains and losses, resulting in multiple mosaic aneuploidies, which explains a great phenotypic variety and may predispose to the development of cancer. Bi-allelic mutations in CEP57 are the cause of MVA2. CEP57 encodes a centrosome protein involved in microtubule stabilization and is crucial for maintaining prope...

The main role of the acid-labile subunit (ALS) is to stabilize the IGFBP3/IGF complexes. Pathogenic variants in the gene coding for ALS (IGFALS) results in IGF1 and IGFBP3 deficiency, short stature, delay puberty and insulin resistance. The aim of these study was to identify the genetic cause in a patient with suspected ALS deficiency. The proband is the third son of non-consanguineous parents, evaluated for the first time at 17.3 years due to short stature (−2....

Background: In a population of a community-based setting (BMISDS range −3.5 to +4.1), there is a negative linear correlation between childhood BMISDS and pubertal height gain, together with earlier onset of pubertal growth with higher BMISDS for both sexes (1).Objective: To investigate the impact of BMI in childhood on the pubertal pattern of growth for obese children in a clinical setting.Met...

Introduction: Non-classical congenital adrenal hyperplasia is the most common pathological cause of early pubarche in prepubertal patients. However, this may also be the first manifestation of central precocious puberty or an androgen producing suprarrenal or ovarian tumor.Objective: To present a clinical case initially misdiagnosed as Congenital Adrenal Hyperplasia that turned out to be an Ovarian Tumor of Leydig Cells.Clinical ca...

Background: Hypothalamic obesity (HyOb) is a rare form of treatment-resistant morbid obesity associated with congenital or acquired hypothalamic damage. Its pathophysiology has been attributed to hyperphagia and hyperinsulinaemia. The wider roles of oxytocin (OXT) in regulating appetite and weight have recently emerged in animal and human studies, but there is no human evidence that hypo-oxytocinaemia contributes to weight gain.Hypothesis: Hypo-oxytocina...

Background: Mouse studies have demonstrated the necessity of Sonic Hedgehog (SHH) for normal proliferation of Rathke’s pouch (RP) precursors. However, the possible function of SHH in pituitary cell specification remains to be assessed. Additionally, evidence suggests that SHH may be relevant in human adamantinomatous craniopharyngioma (ACP), a histologically benign, but clinically aggressive childhood tumour associated with high morbidity.Objective ...

Background: The central precocious puberty (CPP) diagnosis is usually based on clinical evaluation but in its soon phase this evaluation is difficult so laboratory confirmation is crucial.Objective and hypotheses: To evaluated the usefulness of the Leuprolide stimulation test as a diagnostic method of idiopathic CPP.Method: Sixty-one girls, aged 5–8 years, were evaluated retrospectivaly for premature breast development. Girls ...

Introduction: The circadian rhythmicity of the hypothalamic–pituitary–adrenal (HPA) axis depends on the synchronization of the clock molecular systems in the suprachiasmatic nucleus and in the adrenals. When and how this process occurs in the adrenal is unknown.Objective: To assess the ontogeny of daily variation of the expression of the adrenal clock genes (Clock, Arntl, Per1, Per2, Per3, Cry1, Cry2, Rora, and Nr1d1), steroid...

Background: Maternal diabetes is a pathologic state that increases the incidence of complications in both the mother and the foetus. Patients with diabetes mellitus (DM) may exhibit reproductive abnormalities, including PCOS and hypogonadotropic hypogonadism. Diabetes during pregnancy is an endocrine disruptor and studies performed in animal models have shown abnormalities in gonadal function in the offspring, but it is unknown whether pre-gestational (PGDM) and gestational di...

Background: IGF1 measurements are used to diagnose and monitoring GH related disorders. GH dose is titrated against IGF1 concentrations which should be kept within the age-and sex-related normal range. However, IGF1 results vary widely depending on the immunoassay used. International guidelines advise to report IGF1 results as S.D. scores from an assay-specific age-related reference population.Objective and hypotheses: Our objective was to...
