Background: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders characterized by a defect in cortisol biosynthesis. The most common form of CAH is the 21-hydroxylase deficiency (21-OHD), however, the incidence and the etiologic spectrum of other forms of CAH were not reported.Objective and hypotheses: This study describes the etiological distribution and clinical characteristics of CAH in a single academic centre.<p class...

Background: Prader-Willi syndrome (PWS) is caused by the deletion of the paternally-derived 15q11-13 region or the maternal uniparental disomy of chromosome 15 (mUPD(15)). Puberty is usually delayed and central precocious puberty (CPP) is very rare in PWS.Objective and hypotheses: This study was undertaken to correlate clinical features focusing on pubertal progression with genotype with or without MKRN3 deletion to understand the mechanism of C...

Background: Pseudohypoparathyroidism (PHP) is a heterogeneous group of disorders characterized by hypocalcemia, hyperphosphataemia and Albright hereditary osteodystrophy (AHO), resulting from abnormalities of GNAS.Objective and hypotheses: This study investigated clinical features, outcomes, molecular characteristics of patients with PHP and pseudopseudohypoparathyroidism (PPHP).Method: Thirty one patients (15 males and 16...

Background: Permanent neonatal diabetes mellitus is caused by mutations in the KATP channel subunits. DEND (Developmental delay, Epilepsy, and Neonatal Diabetes) syndrome is the most severe form of permanent neonatal diabetes. We experienced a patient with DEND syndrome, who was initially misdiagnosed as type 1 diabetes, who has been successfully switched from insulin injection to oral sulfonylurea therapy.Case presentation: A 50-day-old male ...

Objectives: Short stature is the main characteristics for Turner syndrome (TS) patients, and growth hormone (GH) therapy has been used as an essential treatment for developing final adult height. However, there are only a few studies on the difference responsiveness to GH therapy according to the karyotype of Turner syndrome in Korea. The aim of this study was to analyze the effect of different types of TS karyotype abnormality on the response of GH therapy.</...

Purpose: Androgen insensitivity syndrome (AIS) is a rare X-linked recessive disorder caused by unresponsiveness to androgen because of mutations in the AR gene. Here, we investigated the clinical outcomes and molecular spectrum of AR variants in patients with AIS attending a single academic center.Methods: This study included 19 patients with AIS who were confirmed by molecular analysis of AR. Clinical features and endoc...

Neonatal diabetes mellitus (NDM) is a hyperglycemic status usually diagnosed before first 6 months of life, which is caused by monogenic mutations. INS gene mutation is the second most common cause of permanent NDM, causing misfolding of proinsulin and accumulation in the endoplasmic reticulum, leading to apoptosis of the pancreatic beta cells. We report a case of NDM in a 2-month-old girl with a novel heterozygous mutation of the INS gene, and functional studies to confirm th...

Introduction: Post-marketing surveillance registries provided extensive information about the safety and efficacy of daily growth hormone (GH) therapy during treatment. With the availability of novel long-acting GH (LAGH) therapies, it is important to determine whether the novel molecules or the different pattern of GH exposure lead to changes in the efficacy and safety profile. Therefore, new surveillance registries of LAGH are warranted.<p class="abstext...

This study aimed to evaluate the long-term safety and effectiveness of recombinant human growth hormone (rhGH; Eutropin®, Eutropin®Pen, Eutropin®AQ, and Eutropin®Plus, LG Chem, Ltd.) treatment in Korean pediatric patients. This observational study has been conducted since 2011, and the data were collected up to August 2021 for interim analysis. The incidence rates of all adverse events (AEs) were assessed for safety a...

Objectives: This study aimed to evaluate the long-term safety and effectiveness of recombinant human growth hormone (rhGH) (Eutropin® Inj.., Eutropin®Pen Inj., Eutropin®AQ Inj., and Eutropin®Plus Inj., LG Chem, Ltd.) based on the interim analysis of a 7-year accumulated data of the LG Growth Study (LGS) in Korean pediatric patients with growth disorders including growth hormone deficiency (GHD), T...
