Background: Gonadotropin-releasing hormone (GNRH) and its receptor (GNRHR) are central regulators of puberty. Loss-of-function mutations of the GNRH-GNRHR signaling pathway are associated with congenital hypogonadotropic hypogonadism, but no mutations were reported so far in patients with central precocious puberty (CPP). Animal data demonstrate the importance of microRNAs in pubertal timing regulation. Among others, miR200b regulates Gnrh1 gene expression in GnRH neu...

Background: An accurate prediction of final height after the first year of growth hormone (GH) treatment may help clinicians to give parents and children more realistic expectations.Objective and hypotheses: To validate two prediction models (with and without max. GH peak) for near final adult height (nFAH) by Ranke et al.Method: Height data of 142 (93 male) idiopathic GH deficient (iGHD) children, treated with GH for at l...

Introduction: Donohue syndrome (DS) is presenting as the most severe form of insulin resistance. Most of the patients are dying within the first two years of life. As potential treatment has been described the administration of rhIGF1 (Mecasermin) to stimulate the pathway of insulin-like action. An improved metabolic control was reported with continuous subcutaneous administration of rhIGF1 instead of twice daily injections [Plamper 2018].<p class="abstext...

Background: Inhibin consists of two homologous subunits, the α (INHA) and the βA or βB subunits (INHBA/INHBB). Both inhibins play an important role in the hypothalamic-pituitary-gonadal axis by regulating the follicle stimulating hormone levels. INHA knockout mice develop mixed or incompletely differentiated gonadal stromal tumours. In females, some INHA variants have been associated with primary ova...

Introduction: The National Registry of Civil Status through circular 33 of February 24, 2015 instructed the guidelines for the allocation of a sex through an inscription on the Civil Registry of Birth for intersexual minors.Objective: To create clinical and medical awareness on the importance of making an accurate diagnosis of Congenital Adrenal Hyperplasia CAH in order to avoid adverse effects due the omission of the due diligence by violating of the pr...

Background: An activation cascade of specific genes sets up the initiation of sex determination leading in males to testes formation and synthesis of testicular hormones. Disruption of this gene cascade may cause a spectrum of disorders/differences of sex development (DSD) phenotypes. Here we describe for the first time two sisters suffering from 46,XY DSD, who by whole exome sequencing were shown to carry a mutation in the X-linked StAR-related lipid transfer...

Introduction: Advanced glycation end-products (AGEs) are heterogeneous groups of irreversible adducts resulting from non-enzymatic glycation and glyoxidation of proteins, lipids, and nucleic acid. AGEs and its cell receptor RAGE have been involved in the pathophysiology of cardiovascular and metabolic diseases. Interaction of AGEs with RAGE results in an increased generation of oxygen radicals and increased expressions of pro-inflammatory cytokines. Circulating soluble AGE rec...

Background: There is little information on growth and fractures in boys with Duchenne Muscular Dystrophy (DMD).Objective & hypotheses: To determine the extent of growth & skeletal morbidity in a contemporary cohort of DMD in the UK.Method: Clinical details of 832 boys with DMD in the North Star database (2006–2015) from 23 centres were analysed following categorisation into five age groups: A:<5 years (n, ...

Aim: To delineate the diagnosis in a case of antibody negative infantile onset diabetes with deranged liver function.Case Report: A female child, first born of consanguineous couple presented with Diabeteic Keto Acidosis and acute liver failure at 9 months of age. She has been treated as a case of Type I diabetes and was discharged on insulin. Child was further evaluated at our center at 11 months of age. On examination, she had a normal anthropometry an...

Background: Heterozygous de novo variants in SAMD9 cause the complex multisystem growth disorder, MIRAGE syndrome. Core features are myelodysplasia, infection, restricted growth, adrenal hypoplasia, genital/gonadal phenotypes, and enteropathy. However, the range of additional associations is expanding and includes disrupted placental development, poor post-natal growth, and other endocrine features. Milder phenotypes are also described, such ...
