Spondyloepiphyseal dysplasia tarda (SEDT) is an inherited disorder that is diagnosed in childhood or adolescence presents with disproportionate short stature and premature osteoarthritis with frequently affecting men. Here, we described a novel nonsense mutation, c.508A>T; p.Lys170Ter, in TRAPPC2 in a Turkish patient with X-linked SEDT. The patient is a 15-year-old boy from Turkish non-consanguineous parents, presented decreasing height velocity last three years and also th...

Thyroid hormone is crucial for metabolism and development. Cellular thyroid hormone homeostasis requires adequate function of (i) thyroid hormone transporter proteins, (ii) deiodinating enzymes and (iii) nuclear receptors. Thyroid hormone transporters are crucial for cellular uptake of T3 and T4. Over the last years, a number of thyroid hormone transporters have been identified and their physiological relevance has been established. The most well-studied example is MCT8 defici...

Background and Objectives: N-terminal-pro hormone Brain Natriuretic Peptide (NT-proBNP) and hs-Troponin T (hs-TnT) are commonly used cardiac biomarkers despite lacking a deeper understanding about influencing parameters especially in the healthy pediatric population. We previously found associations between NT-proBNP and hs-TnT and a child´s age, sex, pubertal status, Body Mass Index (BMI) and serum lipid levels. Subsequently, we explored associations wi...

Introduction: After contact with the antigen, lymphocytes require activation for proliferation and differentiation into effector cells. Activation of lymphocytes results in the expression of activation markers. The CD69 antigen appears first on the surface of lymphocytes. This occurs one hour after receiving the activation signal. The CD69 molecule acts as a cellular stimulating signal, causing further activation and proliferation of cells, stimulating the syn...

Background: Growth Hormone Insensitivity (GHI) is characterised by short stature and functional IGF-I deficiency associated with normal/elevated GH levels. Marked genetic and phenotypic heterogeneity exist, and heritable defects in GH-IGF-I axis genes/associated pathways account for mild-moderate to severe GHI cases. We report twin brothers from a non-consanguineous kindred who present with short stature and bi-allelic mutations in QSOX2 encoding the nuclear m...

We introduce the ReTRIACt Trial (NCT05579327) of tiratricol (Triac) for MCT8-deficiency, a rare X-linked disease resulting from disordered thyroid hormone transport and characterized by profound neurodevelopmental delay and features of chronic peripheral thyrotoxicosis. The ReTRIACt Trial aims to verify the effects of tiratricol observed in previous studies. It is a double-blind, randomized, multicenter, placebo-controlled study to evaluate the effects of tiratricol discontinu...

The experiences of older adults with Variations in Sex Characteristics (VSC or Differences/Disorders in Sex Development/DSD) are well documented. However there has been a gap in the literature with respect to representing the voices of younger people. This qualitative research study has been conducted in collaboration with Intersex Trust Aotearoa New Zealand. Ten young people with VSC were recruited via health professionals, intersex advocates, support groups and social media ...

Introduction: Hypogonadotropic hypogonadism (HH) is a rare condition, where a definitive diagnosis is often hard to reach.Objectives: To describe the clinical, biochemical and genetic findings in cases with suspected HH in the West of Scotland who were referred for genetic analysis between 2016 and 2020.Methods: Information was collected on clinical assessment including family hist...

Background: Growth hormone insensitivity (GHI) encompasses normal/elevated growth hormone (GH), low IGF-I levels and growth restriction. Non-classical/mild-moderate GHI is an emerging entity which is poorly characterised, and, in many subjects, the underlying cause is unclear. Heterozygous dominant negative (DN) variants located in the intracellular/transmembrane domain of the GH receptor (GHR) cause a ‘non-classical’ GHI phenotype.<p class="abst...

Abstract: Hypoglycemia is a frequent and one of the major metabolic emergencies in any age, causing a significant dilemma to reach the correct diagnosis and perform the appropriate management. it Has potentially devastating consequences on brain development and cognitive functions. It Is a heterogeneous disorder with many different possible etiologies, including hyper-insulinism, glycogen storage diseases, fatty acid oxidation defects, hormonal deficiencies (g...
