Introduction: In cases of disorder of sex development (DSD), the change between the gender assigned at birth and the individual's chosen gender identity can occur especially after puberty.Aim: was to determine the relationship between genetic sex, gender assigned at birth and gender identity, and the importance of molecular diagnosis.Method:154patients older than 14years of ag...

Aggrecan (ACAN) is the major proteoglycan in the articular cartilage, critical for the structure and function of growth plate cartilage.Case Report: 11-year-old (y) boy admitted at 1.8 y of chronological age (CA), due to poor growth rate Height (H): 76 cm (−2.75 SDS). Initial physical examination: mild dysmorphic features and prepubertal external genitalia (two scrotal testes, 1 cc volume each). Neurologic maturation was normal. Initial bo...

Background: Isolated Growth Hormone Deficiency (IGHD) is usually associated with a delayed bone age. A genetic cause for IGHD is more frequently found in patients with familial cases and/or consanguineous parents.Objective and hypotheses: To diagnose the genetic cause of IGHD and clarify the unusual clinical presentation of advanced bone age in one patient born to consanguineous parents.Method: Sanger sequencing of GH1, <e...

Background: The age at weaning programs life history adaptively. Shorter infancy resulted in longer/thinner animals with a reproductive-strategic shift to earlier physical and sexual development (BMC Med, 2013).Hypotheses: The length of infancy impacts also the stress-response and has behavioural consequences.Method: Sprague-Dawley pups (generation F1), which usually are weaned at age 21 days, were weaned by cross-fostering at age ...

Introduction: Alström syndrome is a rare autosomal recessive disorder characterized by type 2 diabetes, early-onset obesity, hypogonadism, dyslipidemia, progressive retinal degeneration, sensorineural hearing loss, cardiomyopathy and renal failure.Case Report 1: A 13 years-old girl consulted because of high blood glucose (442 mg/dl). HbA1c was 8.9%, C-peptide was 4.5 g/dl, insulin was 17.5 μU/ml, insulin antibodies were negative. The parents we...

Background: Premature adrenarche (PA) has been associated to increased metabolic risk. Areas of controversy regarding associated co-morbidities are precocious pubarche, PCOS and lower birth weight, which may depend on ethnic background.Objective and hypotheses: To describe the risk of precocious thelarche (PT, <8 years), pubarche (PP, <8 years F, <9 years M) and gonadarche (PG, <9 years) in children with premature adrenarche.<p class=...

Background: We have proposed a simple and comprehensive scoring system to evaluate clinical features of differences/disorders of sexual development (DSD); however, its clinical evaluation has not been performed.Aim: To evaluate the association between this newly proposed DSD scoring system (DSD-SS) and assigned gender in patients with 45,X/46,XY mosaicism.Methods: DSD-SS involves e...

Introduction: Consensus guidelines (2021) state that a second dry blood spot (DBS) should be considered for newborn screening (NBS) in preterms (delayed TSH rise).Objective: To evaluate the diagnostic yield of an NBS strategy including a second DBS at 14 days in preterms.Material and Methods: Retrospective study of 2 cohorts. Cohort 1: live births <37 weeks of gestational age (G...

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...

Background: Wolfram syndrome (WS) is a rare autosomal recessive disorder, characterised by early-onset diabetes and optic atrophy. It is caused by mutations in WFS1.Objective and hypotheses: This study aimed to comprehensively review the natural history of WS in a large cohort of patients from the EURO-WABB registry.Method: Data from EURO-WABB patients with WS was analysed in conjunction with the Leiden Open Variation Data...
