Context: PPP2R3C encodes the B”gamma regulatory subunit of the protein phosphatase 2A (PP2A), which is a serine/threonine phosphatase involved in the phospho-regulation processes of mammalian cells. We have recently reported homozygous and heterozygous mutations in PPP2R3C in patients with syndromic 46,XY complete gonadal dysgenesis (MEGD syndrome) and impaired spermatogenesis, respectively. In this study, we have further investigated th...

Objectives: Children with growth hormone deficiency (GHD) are usually treated with once-daily injections of recombinant human growth hormone (rhGH). Somatrogon is a long-acting rhGH (LAGH) approved in the EU and other countries for once-weekly treatment of children with short stature. The Pfizer Registry of Outcomes in Growth hormone RESearch (PROGRES) study will assess the long-term safety and effectiveness of once-weekly somatrogon and once-daily rhGH prepar...

Background: Bardet-Biedl syndrome (BBS) is a rare, autosomal recessive, clinically and genetically heterogeneous, pleiotropic disease characterized by the immotile primary cilia, leading to an MC4R pathway impairment. In addition to syndromic features, patients present with hyperphagia, early-onset obesity, metabolic syndrome (MetS) and increased risk of type 2 diabetes. Here, we aimto describe metabolic features and MetS z-score in a group of rare BBS cases.<...

Introduction: Treatment adherence is crucial for the success of Growth Hormone (GH) therapy. Non-adherence rates have varied over a wide range from 5% to 80% in the literature. Several factors may have an impact on treatment adherence. Besides, with the COVID-19 pandemic that affected the whole world, there were problems with the hospital admission and routine controls of the patients who used GH treatment.Objective: The...

Background: Approximately 10-15% of small for gestational age (SGA) newborns are at risk of having subnormal growth and persistent short stature. It is postulated that a large amount of persistent short stature results from genetic abnormalities, which are commonly characterized by dysmorphic features and developmental disorders.Aim: To uncover the genetic etiology of syndromic short stature children born SGA.<p clas...

Background: Congenital hypothyroidism(CH) is the most common neonatal endocrinological disorder in the world. Although most of the CH is sporadic, some genetic defects are responsible from the etiology. The aim of this study was to determine the genetic and etiological factors of CH.Methods: 49 patients(female;n=24), from 24 families were included in the study. The data, collected retrospectively, consisted ...

Introduction: Classic congenital adrenal hyperplasia (CAH) caused by 21-hydroxylase deficiency results in impaired synthesis of gluco- and often also of mineralocorticoids. Early treatment with glucocorticoids and mineralocorticoids prevents life-threatening crises. In some centres, additional salt is prescribed in the first year. However, until now the use of salt is controversial and not proved to result in better outcome in studies.<s...

Background: Rokineticin receptors (PROKR1 and PROKR2) belong to the family of G protein-coupled receptors. Bi-or mono allelic mutations in PROKR2 gene have been identified in Kallmann syndrome which is characterized by hypogonadotropic hypogonadism and anosmia/hyposmia. Recently, PROKR2 mutations were reported in patients with multiple pituitary hormone (MPHD) and growth hormone deficiencies (GHD), suggesting a potential role for the PROK2 p...

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: 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...
