Ovarian Development and Hormonal Feedback Mechanism in a 46XX Patient with cyp19a1 Deficiency Under Low Dose Estrogen Replacement

Burckhardt Marie-Anne , Obmann Verena , Janner Marco , Mullis Primus E

Background: Ovarian and uterine development in relation to hormonal feedback mechanisms (E2, LH, FSH, and inhibin) has rarely been studied. Therefore, the age specific and longitudinally adequate replacement dose of estradiol to achieve normal maturation in terms of ovarian and uterine development during infancy, childhood and adolescence remains not well known. However, aromatase deficiency offers an excellent model to study the relevant estradiol dose needed to ac...

Goliath, a Variant of DAVID Syndrome?

Hasselmann Caroline , Samuels Mark E , Van Vliet Guy

Background: DAVID syndrome (deficit in anterior pituitary function and variable immune deficiency) (J Clin Endocrinol Metab 97 E121, 2012) can be caused by NFKB2 mutations (Am J Hum Genet 93 13, 2013). All patients have an orthotopic posterior pituitary (PP) and most only ACTH deficiency.Objective and Hypothesis: To describe a girl with common variable immunodeficiency (CVID), ectopic PP (EPP) ...

Determination of the Pathogenicity of SHOX P2 Promoter Variants, Identified in Patients with Léri-Weill Dyschondrosteosis or Idiopathic Short Stature

Belinchon Alberta , Benito-Sanz Sara , Heath Karen E

Background: Expression of SHOX, a transcription factor implicated in skeletal development, is regulated by the interaction of two promoters, weak, P1 (exon 1) and strong, P2 (exon 2), with at least, seven enhancers. SHOX haploinsufficiency, due to mutations in SHOX or its enhancers, explains ~70% of Leri-Weill dyschondrosteosis (LWD) and ~2.5% idiopathic short stature (ISS) cases whilst the underlying molecular mechanism in the remaining is unknown.<p...

Characterisation of Partial SHOX Deletions/Duplications Reveals Intron 3 to be a Hotspot Region

Benito-Sanz Sara , Belinchon Alberta , Heath Karen E

Background: SHOX, located on the pseudoautosomal region 1 (PAR1), encodes a transcriptional factor implicated in human skeletal growth. Alterations in SHOX or its regulatory elements are observed in ~70% of patients with Leri–Weill dyschondrosteosis (LWD), in ~90% with Langer mesomelic dysplasia (LMD) and ~2.5% of patients with idiopathic short stature (ISS). SHOX deletions/duplications are a frequent alteration, with the majority encompassing the entire gene.<p class...

Continuous Glucose Monitoring (CGM) Reveals Undertreated Hypoglycemia in Patients with Congenital Hyperinsulinism

Hood Davelyn E. , Roberts Brian K. , Neale Ann , Raskin Julie ,

Introduction: Congenital Hyperinsulinism (CHI) is the most frequent cause of severe, persistent hypoglycemia in children. Despite current treatments, patients/caregivers report continued hypoglycemia according to the HI Global Registry 2020 Annual Report. Published literature characterizing hypoglycemia in CHI patients on standard of care (SOC) therapies is lacking.Objective: To quantify the extent of hypoglycemia in CHI...

Emerging phenotypes linked to variants in SAMD9 and MIRAGE syndrome

P. Suntharalingham Jenifer , Ishida Miho , E. Stalman Susanne , Solanky Nita , E. Moore Gudrun , C. Achermann John , Buonocore Federica

Background: Heterozygous de novo variants in SAMD9 cause the complex multisystem growth disorder, MIRAGE syndrome. Core features are myelodysplasia, infection, restricted growth, adrenal hypoplasia, genital/gonadal phenotypes, and enteropathy. However, the range of additional associations is expanding and includes disrupted placental development, poor post-natal growth, and other endocrine features. Milder phenotypes are also described, such ...

LRH1 Rescues SF1 Deficiency for Steroidogenesis in vitro but Cannot Explain the Broad Phenotype of SF1 Deficiency in men

Camats Nuria , Fernandez-Cancio Monica , Audi Laura , Andaluz Pilar , Mullis Primus E , Carrascosa Antonio , Fluck Christa E

Introduction: Steroidogenic factor1 (SF1/NR5A1) regulates adrenal and sex development and function. SF1 mutations manifest with a broad phenotype; generally in 46,XY individuals with disorders of sex development (DSD) and in women with ovarian insufficiency. So far, no genotype–phenotype correlation has been found. We hypothesized that the broad phenotype of SF1 mutations may be due to a second hit in a gene with similar function. Liver receptor homolog-1 (LRH1/<...

Radio-guided surgery using 68Ga-labelled Exendin in patient with congenital hyperinsulinism

Prasad Vikas , Kühnen Peter , Rothe Karin , Hauptmann Kathrin , Boss Marti , Gotthardt Martin , Brenner Winfried , Beindorff Nicola , Blankenstein Oliver

Congenital hyperinsulinism (CHI) is a life-threatening disease and manifests in the majority of cases in the first days after birth. Based on the distribution of affected cells, focal CHI forms are distinguished from diffuse CHI forms. Focal forms occur in most cases due to a paternally inherited heterozygous mutation in a subunit of an ATP sensitive potassium channel (ABCC8, KCNJ11). Within the diagnostic setting, focal forms can be visualized by 18F DOPA PET scan, as a marke...

The follicle-stimulating hormone receptor is expressed in human pancreatic islet beta-cells and its activation increases glucose stimulated insulin secretion

Aydin Banu K. , Chowdhury Azazul , Incedal Ceren , Wen Quan , Cerenius Sara Y. , Stenlid Rasmus , Forslund Anders , Idevall Olof , Bergsten Peter

Background: Follicle-stimulating hormone (FSH) plays a key role in reproduction. The G-protein coupled FSH receptor (FSHR), is expressed primarily in gonads, and specifically binds FSH. FSHR is also expressed in vascular endothelium, osteoclasts, adipose tissue, monocytes and rodent pancreatic islets. Elevated FSH levels are associated with development of obesity, insulin resistance, osteoporosis, and cardiovascular disease. In a recent study, we showed that h...
