Osteogenesis Imperfecta Type I Caused by a Novel Mutation in the Start Codon of the COL1A1 Gene in a Korean Family and the Course of Pamidronate Treatment for 1 Year

Cho Sung Yoon , Jin Dong-Kyu , Yu Jae-Hong , Han Heon-Seok

Background: A 3-year-old boy appeared healthy at birth and did not experience any fractures until 12 months of age. Blue sclera, frequent fractures without adequate trauma, nearly normal stature, the absence of dentinogenesis imperfecta, no bony deformity, and no limitation of mobility were characteristics suggestive of OI type I that were observed in the patient. The patient’s mother had blue sclera and a history of frequent fracture episodes until the age of 15 years.</...

Hypothalamic Obesity in Children with Craniopharyngioma: Prevalence and Risk Factors of Obesity and Longitudinal Trends of BMI

Cho Ja Hyang , Kim Ja Hye , Kim Yoo-Mi , Choi Jin-Ho , Yoo Han-Wook

Background: Craniopharyngioma is the most common parasellar tumor in childhood arising from remnants of Rathke’s pouch. As the hypothalamus plays a vital role in regulation of body weight by balancing energy intake and expenditure, hypothalamic damage by structural lesions is one of the most common causes of hypothalamic obesity. This study investigated prevalence, risk factors for the development of hypothalamic obesity, and consequent morbidities in children following t...

Endocrine Complications of Patients with Hepatic Type of Glycogen Storage Disease

Lee Yena , Kim Yoo-Mi , Oh Arum , Kim Gu-Hwan , Hee Lee Beom , Choi Jin-Ho , Yoo Han-Wook

Background: Glycogen storage disease (GSD) is an inherited metabolic defect of metabolic defect of glycogenolysis and gluconeogenesis. Patients with GSDs are associated with endocrine abnormalities such as short stature, delayed puberty, fasting hypoglycemia, and dyslipidemia. In addition, patients with GSD 1b are also at risk of autoimmune hypothyroidism. Therefore, this study was performed to investigate endocrine complications in patients with GSD.<p cl...

Genetic Etiologies and Gender Outcomes of Patients with Disorders of Sex Development Presenting with Asymmetric Gonads

Oh Arum , Kim Yoon-Myung , Hun Seo Go , Kim Gu-Hwan , Choi Jin-Ho , Yoo Han-Wook

Purpose: Patients with mixed gonadal dysgenesis (MGD) and ovotesticular disorders of sex development (DSD) usually present with asymmetric gonads. Differential diagnosis of these conditions is based on karyotype and pathological findings of gonads. However, it is difficult to determine sex of rearing and to predict long-term outcomes. This study investigated the clinical features, karyotype, sex of rearing, and pubertal outcomes of patients with MGD and ovotesticular DSD.<...

The Aetiological Spectrum of Congenital Adrenal Hyperplasia Based on Molecular Genetic Analyses

Choi Jin-Ho , Kim Ja Hye , Kang Eungu , Cho Ja Hyang , Kim Gu-Hwan , Yoo Han-Wook

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...

Correlation of Clinical Phenotype and Genotype of Prader-Willi Syndrome and the Deletion of Paternal MKRN3 Allele in PWS Patients with Central Precocious Puberty

Cho Ja Hyang , Kang Eungu , Choi Jin-Ho , Kim Gu-Hwan , Seo Eul-Ju , Yoo Han-Wook

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...

Clinical and Molecular Characterisation of Patients with Pseudohypoparathyroidism

Kang Eungu , Kim Yoon-Myung , Cho Ja Hyang , Kim Gu-Hwan , Choi Jin-Ho , Yoo Han-Wook

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...

A Case of DEND (Developmental Delay, Epilepsy, and Neonatal Diabetes) Syndrome with Heterozygous KCNJ11 Mutation Successfully Treated with Sulfonylurea Therapy

Kim Ja Hye , Cho Ja Hyang , Kang Eungu , Choi Jin-Ho , Kim Gu-Hwan , Yoo Han Wook

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 ...

Long-term endocrine sequelae after hematopoietic stem cell transplantation in children and adolescents

Yoon Ji-Hee , Choi Yunha , Hwang Soojin , Lee Yena , Hye Kim Ja , Choi Jin-Ho , Yoo Han-Wook

Purpose: As the survival rate for pediatric cancers increases significantly with advances in treatment modalities, long-term endocrine complications have also risen. This study investigated the frequencies and risks of endocrine sequelae of childhood cancer survivors after hematopoietic stem cell transplantation (HSCT).Methods: This study included 200 pediatric patients who underwent HSCT. Clinical and endocrinological f...

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...
