Wilson disease (WD) is a relatively common genetic hepatic disease in pediatric area and is characterized by excessive copper accumulation, predominantly in the liver and brain. It is an autosomal recessive disease caused by an ATP7B mutation that causes brain degeneration and is potentially fatal if diagnosed late or untreated. In the early phase of WD, its initial presentation may include mild hepatic involvement that may not be noticable. In obese patients, WD coul...

Gonadotropin-releasing hormone (GnRH) stimulation test is the gold standard test for diagnosing central precocious puberty (CPP), which needs time and effort to perform. Recently, many studies confirmed that Insulin-like growth factor-1 (IGF-1) is involved in the initiation and progression of puberty. With this inspection, we assumed that the IGF-1 level might be correlated with the pubertal stage in central precocious puberty. This study aimed to investigate the value of IGF-...

Background: Prader-Willi syndrome (PWS) is a genetic disorder associated with developmental delay, obesity, and obsessive behavior related to food consumption. Treatment options for weight control in those patients is limited and there are controversies for a surgical approach. Saxenda® (liraglutide) injection 3 mg is indicated as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in adult patients with obes...

Background: Genetics plays a strong role in height. However, for most patients, no cause for the short stature can identified. Whole-exome sequencing (WES) is becoming an increasingly important tool for detecting novel genetic causes of short stature. Blood is the preferred DNA source for germline studies using WES. However, DNA from saliva is a more convenient and cost-effective alternative.Objectives: We aim to identif...

Purpose: This study aimed to describe gene mutations and growth outcome in patients with 21-hydroxylase deficiencyMethods: Subjects were diagnosed as 21-hydroxylase deficiency by direct Sanger sequencing or multiple ligation-dependent probe amplification analysis and visited Pusan National University Children's Hospital from July 2008 to April 2019.We investigated the genotype, phenotype and growth profiles.<p cl...

Introduction: Childhood hypophysitis (CH) is an extremely rare entity that has difficulties in definition and displays a wide variety of symptomatology. The volume and shape of pituitary gland may increase in physiological periods such as puberty and pregnancy, it may also change in various neuroendocrine and psychiatric diseases. It is important to distinguish physiological changes observed in the pituitary, especially in puberty, from hypophysitis.F...

Hypochondroplasia (HCH) is an autosomal dominant inherited skeletal dysplasia with abnormal growth pattern and inadequate pubertal growth spurt. Achondroplasia and HCH have many similar phenotype, however, HCH show the mildest phenotype among FGFR3-associated skeletal dysplasia, and the radiologic findings are usually so subtle. We investigated to evaluate clue for the hypochondroplasia, and clinical and genetic characteristics of eleven Korean patients with HCH. We a...

Prolactinoma is most common functioning pituitary adenoma(50%). However, there have been limited studies for prolactinoma in adolescents. Pituitary adenomas are uncommon in childhood and adolescence (<3% of childhood supratentorial tumors, 3–6% of all surgically treated adenomas). The aim of this study is to assess the characteristics of Korean adolescents with prolactinoma and their clinical course. This study is retrospective cohort study. Patients diagnosed with pr...

Introduction: Crooke’s cell adenoma (CCA) is an aggressive subtype of corticotroph adenoma, it is usually large, frequently invades surrounding tissues, and is resistant to both surgery and radiotherapy.Case Report: A 13-year-old girl, admitted with weight gain for more than 3 months. Her height was 147.5 cm (-1.5 SDS), weight 58.5 kg (1.1 SDS), BMI 26.89 kg/m2 (2 SDS) and blood pressure was 100/78mmHg. Her i physical exa...

Background: Pediatric thyroid cancer has characteristics that are distinct from adulthood thyroid cancer. Due to its very low prevalence, little is known about the genetic characteristics of pediatric follicular thyroid cancer (FTC).Methods: We investigated genetic alterations in tumor tissues from 15 patients aged < 20 years (median: 14.3 years; range: 2.4-19.0 years) using multifaceted approaches. Whole-exome seque...
