Objective: To study structure disorders of sex development (DSD) 46,XY by one center.Subjects and Methods: It was included 60 patients with diagnosis DSD 46,XY at birth to 18 years. For all patients was conducted structural evaluation of the external (by External Masculinization Score, EMS, 0-12) and internal genitalia (by pelvic ultrasound, n=60, laparoscopy, n=20), hormonal research (testoster...

The majority of individuals with disorders/differences of sex development (DSD) do not have a genetic etiology. However, recently new genes causing DSD have been reported and using the unbiased approach of whole exome sequencing (WES) the diagnostic yield should be improving. Here, we performed WES on a large cohort of 125 individuals all of Algerian origin, who presented with a wide range of DSD phenotypes. Parental consanguinity was reported in 36% of individuals. The geneti...

Background and aims: The introduction of next-generation sequencing (NGS) as an essential tool for the routine molecular diagnosis of DM has highlighted the under-diagnosis of monogenic diabetes mellitus (MonDM). Accurate molecular diagnosis of the MonDM subtype has important implications for prognosis and choice of treatment, family counseling and health management, enabling precision medicine. The main objective was to clinically and molecularly characterize...

Background: Loss-of-function mutations of the androgen receptor (AR) gene result in androgen insensitivity syndrome (AIS) in 46,XY individuals, causing a disorder of sex development. AIS has a clinical continuum according to the resistance severity, being classified into three main categories: complete (CAIS), partial (PAIS), and mild (MAIS). The authors present a female phenotype patient with CAIS.Case Report: An otherw...

Background: Obesity in females is often associated with metabolic complications and hyperandrogenism but the role of adipose tissue (AT) in androgen synthesis remains unclear.Aims/Objectives: Employing human subcutaneous and visceral AT and cultured adipocytes, we studied whether AT could be a source of androgens promoting hyperandrogenism in lean and especially in obese females.Methods</st...

Background: The approach to investigating a newborn with a suspected DSD is likely to vary between centres and may be influenced by local availability.Method: To explore the current diagnostic practice and needs, an international survey of 124 paediatric endocrinologists, identified through DSDnet and the I-DSD Registry, was performed in 2014.Results: A total of 77/124 (62%) clinicians, in 74 centres, from 38/42 (91%) countries res...

Introduction: Complete Androgen Insensitivity Syndrome (CAIS) is characterized by a complete external genitalia appearance and testicular development in 46,XY individuals harboring pathogenic allelic variants in the AR gene. Due to growing evidence regarding the low risk of germ cell tumors (GCT) in AIS. Prophylactic gonadectomy has been debatable in the CAIS management, mainly due to the absence of an accurate biomarker for GCT....

Mandatory lockdown during COVID 19 pandemic obstaculized access to medical attention. Newborn screening (NBS) for congenital hypothyroidism (CH) in Buenos Aires province has been obligatory since 1995 and performed sustainedly. CH causes mental delay if not diagnosed and treated early.Objectives: The aim of this study was to determine if mandatory lockdown changed time of established NBS diagnosis steps.Mat...

Background and Aims: Congenital adrenal hyperplasia (CAH) resulting from 11β-hydroxylase deficiency (11OHD) is a rare autosomal recessive (AR) disorder due to mutations in CYP11B1. Consequences are decreased cortisol secretion, elevated plasma levels of ACTH, and accumulation of steroid precursors causing abnormally high androgen synthesis and hypertension. High levels of 11-desoxycortisol provides diagnosis with certainty. However, in a cohort o...

Introduction: Perrault syndrome is a rare autosomal recessive (AR) disorder (<1:1.000.000). Mutations in several genes, including HSD17B4, HARS2, CLPP, LARS2, TWNK, and ERAL1 have been associated with it, reflecting the genetic and clinical heterogeneity of this condition. It is characterized by bilateral mild to severe sensorineural hearing loss (SNHL) in both sexes and gonadal dysgenesis in 46,XX karyotype females. Ovarian dysfunction ranges from underdev...
