Background: Hypergonadotropic hypogonadism(HH) in females results from primary gonadal failure related to genetic defects affecting ovarian development and function or acquired gonadal damage; limited knowledge exist regarding underlying genes involved or potential gene X environment interactions responsible for disease trait manifestations. While pathogenic variants in single genes, chromosomal abnormalities such as Turner syndrome and acquired gonadal damage...

Introduction: X-linked adrenoleukodystrophy (X-ALD) is a rare autosomal recessive neurodegenerative disease caused by a mutation in the ABCD1 gene. Although its clinical presentation varies, X-ALD is generally characterized by progressive demyelination of the central nervous system, primer adrenal insufficiency, and elevated plasma very long-chain fatty acid (VLCFA) levels. Herein, we aimed to present a case of X-ALD with normal VLCFA caused by a path...

Background: Activation of the Wnt/β-catenin pathway is frequent in adrenocortical tumors (ACTs). This pathway and DAX1, a negative regulator of SF1 expression, control adrenal stem/progenitor cells, which can be involved in ACTs formation.Objective: To analyse the association between the Wnt/β-catenin pathway and the expression of a stem cell marker (NANOG), STAT3, DAX1 and SF1 in ACTs.Methods: Patients:...

Copy Number Variants in Patients with Congenital Hypopituitarism Associated with Complex Phenotypes

Correa Fernanda A , Franca Marcela M , Canton Ana P M , Otto Aline P , Costalonga Everlayny F , Brito Vinicius N , Carvalho Luciani R , Costa Silvia , Arnhold Ivo J P , Jorge Alexander A L , Rosenberg Carla , Mendonca Berenice B

Background: The aetiology of congenital hypopituitarism (CH) is unknown in the majority of patients. In our cohort of 200 cases, it was possible to establish the genetic cause in only 13 patients (6.5%). Copy number variants (CNVs) have been implicated as the cause of genetic syndromes with previously unknown aetiology.Objective: To study the presence of CNVs and its relevance in patients with CH of unknown cause associated with complex phenotypes.<p...

Efficacy and Safety of Corifollitropin Alfa in Combination with Human Chorionic Gonadotropin for Initiation or Restoration of Puberty in Adolescent Males Aged 14 to < 18 Years with Hypogonadotropic Hypogonadism

Shankar R. Ravi , Shah Suneri , Joeng Hee-Koung , Mendizabal Geraldine , Guan Yanfen , Stegmann Barbara J. , Nieschlag Eberhard , Behre Hermann M. , Swerdloff Ronald S. , Fox Michelle C. , Kaufman Keith D. ,

Background: Combinations of follicle-stimulating hormone (FSH) and human chorionic gonadotropin (hCG) have been successful in treating males with hypogonadotropic hypogonadism (HH). The aim of this study was to investigate the efficacy and safety of corifollitropin alfa (CFA), a long-acting FSH analog, combined with hCG to induce testicular growth and pubertal development in adolescent males with HH.Methods: This was a 6...

Oral administration of CRN04777, a nonpeptide selective SST5 receptor agonist, suppresses insulin secretion and rescues hypoglycemia in neonatal rat models of congenital hyperinsulinism

CRN04777 is an orally administered nonpeptide that is a potent and selective agonist of somatostatin 5 (SST5) receptors and is currently under development for the treatment of congenital hyperinsulinism (HI), the most common cause of persistent hypoglycemia in newborns and infants. Congenital HI arises from mutations within the insulin secretion pathway and is characterized by excessive and/or inappropriate insulin secretion by pancreatic islet beta cells. This excess insulin ...

Functional demonstration that variants in the C-terminal of IHH cause short stature and/brachdactyly

Diaz-González Francisca , Modamio-Høybjør Silvia , Lucas-Castro Elsa , Coral Barreda-Bonis Ana , Campos-Barros Angel , González-Casado Isabel , Sentchordi-Montané Lucia , E. Heath Karen

Introduction: Variants in the N-terminal of the Indian-hedgehog gene (IHH) have been associated with Brachydactyly type-A1 (AD) and Acrocapitofemoral dysplasia (AR), only three of which have been functionally studied. However, heterozygous IHH variants, majority classified as variants of unknown significance (VUS) are being increasingly identified, not only in the N-terminal but also in the uncharacterized C-terminal, by NGS, in individuals with short...

Keywords: diabetes, MODY, atypicalIntroduction: Type 1 Diabetes (T1D) is the most common cause of diabetes in childhood, but Type 2 Diabetes (T2D) and monogenic diabetes has attracted increasing attention recently. Cases with atypical diabetes may be challenging for diagnosis, treatment and follow-up management. The purpose of this study was to present the characteristics of atypical diabetes cases from a tertiary referr...

Introduction: Aromatase inhibitors (AIs) are increasingly used in children and adolescents to augment adult height. Given the potential risks of these drugs in women with breast cancer, detailed cardiovascular examinations in adolescents using these treatments are needed to ensure their safety in the pediatric group. The aim of this study was to investigate the effects AIs on cardiac morphology, functions and their relation to several metabolic parameters in a...

Introduction: In rare cases of obesity, genetic defects lead to hyperphagia and severe early-onset obesity. Genetic testing in patients with a suspected genetic obesity phenotype is important, as it can lead to patient-tailored treatment advice. For children, the Endocrine Society (ES) recommends genetic testing in children with early-onset of obesity (<5 years) and hyperphagia. It is unclear whether these recommendations can also be used in adult obesity c...
