Genetic spectrum of 26 Korean patients with congenital hypothyroidism by targeted next-generation sequencing

Oh Arum , Han Heon-Seok

Introduction: Congenital hypothyroidism (CH) is caused by underdeveloped thyroid gland or defect of thyroid hormone synthesis. The prevalence of CH in Korea is 1 per 4,225 people, and DUOX2 mutations were previously known as the most prevalent mutation in Korean patients with CH. This study was performed to identify the correlation between etiology and genetic mutations in patients with CH in a single tertiary hospital.Methods:</...

Growth Prognosis of Small for Gestational Age in Korea: Risk of Early Adolescence

chung Myung hee , Oh Seun

Purpose: Small for gestational age(SGA)babies at increased risk of growth retardation. This is very important issues for them but lacks attention. So we hope this study deserves better guidance. The objectives of this paper is to illustrate the importance of this critical issues and to outline growth prognosis at the beginning of adolescence of female and male babies born small for gestational age(SGA) in comparision to controls born appropriate for gestationa...

A case of a newborn diagnosed with CMAMMA suspected of primary immunodeficiency

Oh Arum , Han Heon-Seok

Background and Aims: Combined malonic and methylmalonic aciduria (CMAMMA) is a rare genetic disorder that affects the body's ability to break down certain proteins and fats. It is caused by mutations in the ACSF3 gene, which provides instructions for making an enzyme involved in the metabolism of fatty acids. As a result of the enzyme deficiency, individuals with CMAMMA experience an accumulation of malonic and methylmalonic acids in their blood and urine...

Effects of COVID-19 pandemic on serum vitamin D concentration in Korean children

Choi Jinjoo , Choe Yunsoo , Yang Seung

Purpose: Vitamin D deficiency (VDD) is very common nowadays in children as well as in adults, probably due to decreased exposure to sunlight. COVID-19 pandemic resulted in school closure and decreased outdoor activity in children, which lead to lower chance for exposure to sunlight. It was reported that the higher level of visceral fat was associated with the lower vitamin D levels in children. The aim of this study is whether body mass index (BMI) affect seru...

Mutational Analysis of TSH Receptor and the Clinical Characteristics of Congenital Hypothyroidism

Yu Jeesuk , Lee Seung Ho , Han Kyudong

Purpose: Aetiologies of congenital hypothyroidism (CH) in newborn period are various, and TSH receptor (TSHR) mutation is known as one of them. We evaluated mutational analysis of the gene TSHR and clinical characteristics in the patients with CH or neonatal hyperthyrotropinemia.Method: Mutation analysis was done in 96 children with CH or transient hyperthyrotropinemia who has been managed at the Department of Pediatrics in Dankook University Hospital. C...

A novel mutation of androgen receptor in a patient with complete androgen insensitivity syndrome

Jong Kim Chan , Hwan Chang Seong

Androgen insensitivity syndrome (AIS) is a rare genetic disease caused by mutation in the androgen receptor (AR). The AR is an essential steroid hormone receptor that plays a crucial role in male sexual differentiation and development. Mutations in the AR gene on the X chromosome cause malfunction of the AR so that a 46,XY karyotype male shows some physical characteristics of a woman or a full female phenotype. Depending on the phenotype, AIS can be classified as complete, par...

Changes of Laboratory Findings Before and After Thyroid Hormone Replacement in a Naïve 19.24 Year-Old Female Case of Ectopic Thyroid

Oh Phil Soo , Choi Joong Wan

Background: Hypothyroidsim is known to be associated with liver function, cholesterol and some hormone levels including GH. But, there are fewer reports about the gonadotropin levels in thyroid dysfunction.Objectives and hypotheses: We report here some interesting laboratory findings in a 19.24-year-old severe short stature female case of ectopic thyroid.Methods: Laboratory investigations including the combined anterior pituitary f...

A Considerable Role of NPR2 Mutation in Idiopathic Short Stature: Identification of Two Novel Mutations

Hwang Il Tae , Yi KyungHee , Kim Eun Young , Yang Seung

Introduction: C-type natriuretic peptide (CNP, NPPC gene) and its receptor, natriuretic peptide receptor B (NPR-B, NPR2 gene), is critical for endochondral ossification in growth plate. Biallelic NPR2 mutations are known as acromesomelic dysplasia, type Maroteaux which is characterized by severe short stature. A monoallelic NPR2 mutation has been suggested to mildly impair long bone growth.Obje...

Relationship between Growth Velocity and Change of Serum Insulin-Like Growth Factor-1 (IGF-1), Serum IGF Binding Protein-3 (IGFBP-3) Concentrations, and IGFBP-3 Promoter Polymorphism during Gonadotropin-Releasing Hormone Agonist (GnRHa) Treatment

Yang Seung , Suk Shim Young , Tae Hwang Il

Purpose: This study aims to investigate the effect of GnRHa on GH-IGF-1 axis and to evaluate if −202 A/C IGFBP-3 promoter polymorphism affects the growth velocity during treatment on girls with central precocious puberty (CPP).Methods: Data was collected from 97 girls, diagnosed under 9 year of age and treated by GnRHa for at least 1 year in Kangdong Sacred Heart Hospital between 2014–2015. Their body height, weight, Δ Height standard dev...

Iodine Status in the Neonate and the Effect on Thyroid Function

Yu Jeesuk , Lee Seung Ho , Chang Young Pyo

Background: Sufficient iodine intake is required for the synthesis of thyroid hormone. Thyroid hormone is very important for normal growth and development, especially in newborn period. It is also well known that excess iodine intake may cause adverse effect in thyroid function.Objectives and hypotheses: This study was designed to find the iodine status of the newborn with normal thyroid function confirmed by newborn screening of thyroid function test (T...
