Background: EuRRECa (European Registries for Rare Endocrine Conditions) is a new project incorporating the development of a core endocrine registry and the development of an e-reporting programme for rare endocrine conditions (e-REC) that are covered within Endo-ERN (https://eurreca.net/e-rec/).Methods: 24 Endo-ERN centres within 12 countries participated in a pilot phase of e-REC...

Introduction: The aim of this study was to investigate the molecular genetic etiology and to determine the relationship between genotype and phenotype with targeted next-generation sequence (NGS)analysis.Method: Patients with a clinical diagnosis of OI were included in the study. Initially, mutations in COL1A1 and COL1A2 genes which are known to be most responsible for OI were investigated. In the second step, a targeted...

Objectives: Data on the role of gluten in type 1 diabetes (T1D) pathogenesis are scarce. We aimed to test whether gluten-free diet (GFD) can decelerate the decline in beta-cell capacity in newly diagnosed non-coeliac T1D children.Methods: Forty six children (aged 10.2±3.3 years) were recruited into this non-randomized self-selected intervention trial: 26 started with GFD, whereas 20 remained on standard diet. Main o...

Background: 45,X/46,XY mosaicism is a rare karyotype with a broad phenotypic variation. In patients with a male or predominantly male phenotype, impaired genital development and statural growth have been observed, but little is known about long-term outcomes. Larger multicenter studies are needed.Objective and hypotheses: The aim of this study is to investigate long-term outcomes, namely gonadal function, growth and co-morbidities, in a larger group of m...

Background: Partial Androgen insensitivity syndrome (PAIS) is a rare condition which is associated with a variable phenotype. To date, there are limited data reporting long-term endocrine outcome for this condition.Aims: To determine the outcomes and clinical characteristics for 46, XY males with PAIS, using information from the International DSD (I-DSD) Registry and its clinical users.Methods: The I-DSD Registry and its users were...

Background: Children with Turner syndrome (TS) have a specific growth pattern that is quite different from that of healthy children. Many countries have population specific growth charts for TS.Objective and hypotheses: Considering national and ethnic differences, we undertook this multicentered collaborative study to construct growth charts and reference values for height, weight, and BMI from birth to adulthood for spontaneous growth of Turkish girls w...

Background: Turner syndrome (TS) can manifest with various clinical features depending on the karyotype and the genetic background of affected subjects.Objective and hypotheses: The aim of this study was to evaluate growth parameters from birth to adulthood in girls with TS in a cross-sectional study.Method: A total of 842 patients, with an age of diagnosis ranging from birth to 18 years followed-up between 1984 and 2014, from 35 d...

Introduction: 5α-reductase type 2 deficiency (5α--RD) and 17β-HSD type 3 deficiency (17β-HSDD) are rare differences/disorders of sex development (DSD) in which impairment of steroidogenic enzymes causes undervirilisation in patients with a 46,XY genotype. We aim to enlarge the limited knowledge on long-term gonadal function and gonadal pathology in these conditions.Methods: Data on phenotype, laborato...

Ovarian steroid cell tumors (OSCT) are rare sex cord stromal tumors of the ovary and comprise <0.1% of all ovarian tumors. We herein report a case of an OSCT in a 9 year old girl patient who presented with central puberty preocious unresponsive to gonadotrophine relasing hormon analog (GnRH) therapy. A 9 year old girl presented with breast development noticed 4 months ago and menarche 3 months ago. Her height was 141,5 cm (+1,3 SDS), body weight was 35.4 kg (+0.9 SDS) and...

Background: Hypophosphatasia (HPP) is an inherited multisystem disorder predominantly affecting the mineralization of bones and teeth. HPP is caused by pathogenic variants in ALPL, which encodes tissue non-specific alkaline phosphatase. A major challenge in diagnosing HPP is interpreting variants in ALPL classified as variants of uncertain significance (VUS) according to ACMG/AMP criteria, creating uncertainty in patients and treating physicians resulting in d...
