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: Severe deficiency of 11β-hydroxysteroid dehydrogenase type 2 (11βHSD2) triggers activation of mineralocorticoid receptor (MR) by cortisol and causing apparent mineralocorticoid excess (AME) syndrome characterized mostly by low-renin arterial hypertension and hypokalemia. In 2003, we studied a patient with AME (3 years-old) having two homozygous mutation, D223N (rs121917833) and a SNP C>T in intron 3 (rs376023420) (Carvajal et al. JCEM 2003).<p cla...

Background: In vitro studies suggest a broader role for aldosterone, beyond elevating blood pressure. Clinical data support the notion that aldosterone can directly alter the function of the immune system and can participate in low-grade inflammation which leads to blood pressure elevation and end organ damage.Objective and hypothesis: To assess in humans, whether aldosterone plasma levels and mineralocorticoid receptor (MR) expression associate...

Background: Paediatric hypertension is increasing and has been associated with obesity and insulin resistance. Recently, cortisol:cortisone ratio and the metalloproteinase 9 (MMP9), which is a marker of vascular remodelling, have been syndicated as new risk factors associated with hypertension.Objective and hypotheses: To analyse the association between paediatric hypertension with clinical, biochemical, inflammation, and vascular remodelling biomarkers<...

Background: Primary ovarian insufficiency (POI) is genetically mediated in up to 30% of cases. Many genes associated with POI have roles in early ovary developmental processes, including meiosis.Objectives: We investigated the genetic mechanism underlying early-onset POI in three young women presenting with absent puberty: two sisters from a consanguineous pedigree and a third unrelated proband.<st...
