Background: Islet autoantibodies such as Glutamic Acid Decarboxylase (GAD), Islet antigen-2 (IA-2), Zinc Transporter 8 (ZnT8), and Insulin autoantibody (IAA) are known to be detected at higher frequencies in pediatric patients clinically diagnosed with type 2 diabetes than in adults. Therefore, it is crucial to evaluate them for accurate diagnosis, prognosis, and treatment direction. However, guidelines for when to re-evaluate patients with negative islet auto...

The syndrome of resistance to thyroid hormone (RTH) is caused by decreased tissue responsiveness to thyroid hormone. With the exception, inheritance of RTH is autosomal dominant. The receptors are encoded by two genes (THRA and THRB), each of which undergoes alternate splicing to generate receptor subtypes (TRa1, TRβ1, and TRβ2), with differing tissue distributions.Here we describe a child with novel heterozygous mutations for THRB. Nine-months-old ...

Background: Achondroplasia is the most common condition characterized by disproportionate short stature. Patients with achondroplasia progressively fall below normal standards for length and height. GH has been widely used to treat short stature with or without GH deficiency (GHD).Objective and hypotheses: The purpose of the present study was to clarify the effectiveness of GH therapy on short stature in achondroplasia.Method: The ...

Inborn Errors of Immunity (IEI) include more than 400 disorders representing aberrant function or development of the immune system. Recently, more attention has been paid to the interaction between the immune and endocrine systems. In this study, we aimed to investigate endocrine disorders in a cohort of IEI. We investigated the prevalence, clinical, and laboratory features of endocrine disorders in patients who were diagnosed with IEI from 1994 to 2022 in Samsung Medical Cent...

Introduction: Deficient anterior pituitary with variable immune deficiency (DAVID) syndrome is a rare condition characterized by symptomatic ACTH deficiency and primary hypogammaglobulinemia, caused by a heterozygous mutation in the NFKB2 gene (MIM#164012) on chromosome 10q24. We report the novel mutation of the NFKB2 gene in a Korean boy presenting with gait disturbance, calf pain, and abnormal thyroid function test.<s...

Background: Turner syndrome, a condition that affects only girls and women, result when the X chromosome is missing or partially missing. Ornithine transcarbamylase (OTC) deficiency, the most common inherited urea cycle disorder, is transmitted as a partially dominant X-linked trait. The OTC gene maps to Xp21.1 and spans approximately 73 kb, containing 10 exons and 9 introns. OTC deficiency is diagnosed using a combination of clinical findings and biochemical testing, while co...

Introduction: Kisspeptin is well known gatekeeper of puberty onset to date. However, several neuroendocrine factors are also discovered to be associated with puberty onset and, especially neuropeptide Y (NPY) and neurokinin B, participate in the neuronal network integrating reproduction. However, the interactions between neuroendocrine factors and the reproductive axis have not yet been fully explored. We report herein the expression profile of NPY gene and neurokinin B gene i...

Background and Purpose: The prevalence of non-alcoholic fatty liver disease (NAFLD) in children has been increasing associated with insulin resistance. However, there is a scarcity of related studies in children with NAFLD with type 2 diabetes mellitus (T2DM) compared to adults. We conducted this study to investigate the association between non-invasive diagnostic methods of liver fibrosis and T2DM in pediatric patients with NAFLD.<stron...

Background: Early age at menarche was associated with obesity, insulin resistance, metabolic syndrome, cardiovascular disease (CVD), and mortality in adulthood. Besides, a mother's age at menarche has been suggested to be a likely contributor to a daughter's early menarche. Therefore, this study aimed to determine whether a mother's earlier age at menarche is a risk factor for a daughter's early menarche, obesity, and short stature in young...

Background: Congenital hypothyroidism is the most common neonatal metabolic disorder and detected at a rate of 1 in 3000 to 4000 live births. Compared to congenital hypothyroidism caused by defects in thyroid development leading to thyroid dysgenesis, thyroid dyshormonogenesis has tendency to be detected at older age and its clinical manifestations are individually different. Thus, to evaluate exact causes and predict clinical course for congenital thyroid dys...
