Background: Following the 2010 CAH consensus, the need for genetic confirmation of diagnosis remains uncertain and variation in practice is unclear.Methods: This variation was assessed by using the International CAH(I-CAH) Registry which was developed using the same platform as the I-DSD Registry.Results: After the development of the I-CAH Registry in October 2014, the rate of addition of CAH cases increased from 2/month to 14/mont...

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...

Introduction: There are few longitudinal male cohort studies with serial assessments of growth and puberty.Objective: To describe the design and implementation of a longitudinal cohort study of Russian boys evaluated annually for growth, development and puberty.Design/methods: We assembled a multi-disciplinary team of U.S. and Russian researchers to design and conduct a longitudinal boys’ cohort study in Chapaevsk, Russia with...

Background: The broad spectrum of associated diseases underlying the diverse phenotypes of patients with Turner syndrome (TS) has been extensively described. However, the underlying pathophysiological mechanisms remain unknown. Few studies have analyzed congenital and acquired diseases as a function of karyotype, and conflicting results have been obtained, calling into question the role of haploinsufficiency for genes located on the X chromosome.Objectiv...

46,XY differences of sex development (46,XY DSD) comprise a very heterogeneous group of people amongst DSD. While some conditions are well characterized on the molecular level, e.g. androgen biosynthesis enzyme deficiency or DSD due to genetic variants in the androgen receptor, many 46,XY DSD patients lack a specific diagnosis, especially those people where gonadal development is affected. A specific diagnosis, however, is helpful to develop an individualized management progra...

Introduction: Although, there are several studies that use the external masculinisation score (EMS) for numerical description of the external genitalia in infants with DSD, data on change in EMS in the routine clinical setting are lacking.Objectives: To determine the longitudinal change in EMS and its determinants in a cohort of boys with XY DSD in one specialist centre.Methods: Ob...

Gender dysphoria indicates a psychological distress due to any incongruence between biological sex and gender identity, while transgender identity refers to an individual, whose gender identity is the opposite of the biological sex. The number of gender dysphoric youth seeking hormonal care seems to rise worldwide. Therefore, numerous bioethical and medical controversies are raising about possible side effects of hormonal therapies, including interference with brain developmen...

Background: Children with Sickle Cell Disease (SCD) show endocrine complications and metabolic alterations. The physiopathology of these conditions is not completely understood: iron overload due to chronic transfusions, ischemic damage, and inflammatory state related to vaso-occlusive crises may be involved. Aims of this study were to evaluate the growth pattern and the endocrine and metabolic alterations in a cohort of children with SCD and to detect the relationship between...

Background: Effective clinical care and research in disorders of sex development (DSD), as well as assessment of long-term outcome of these rare conditions, requires multicentre collaboration across national boundaries and across multiple clinical and research disciplines. This registry is currently funded by the UK MRC as the International DSD Registry (www.i-dsd.org) which adheres to the highest standards of data governance and security. Fr...

Study Objective: To describe the clinical presentation and characteristics of DSD in Kenyan children and adolescents.Methodology: This retrospective observational study was carried out at Kenyatta National hospital and Gertrude’s Children’s Hospitals involving 71 patients age 0–19 years with DSD enrolled in the clinics between January 2008 to December 2015.Results: The mean age at the time of diagnosis was 2.7 years ...
