Identification of a novel point mutation in APOB gene in a patient with hypobetalipoproteinemia

Yun Park So , Sik Kim Heung , Lee Donghyun , Kang Seokjin

Familial hypobetalipoproteinemia (FHBL) is an autosomal codominantly inherited disorder of lipid metabolism characterized by <5th percentile plasma levels of LDL cholesterol or total apolipoprotein B (apoB). LDL cholesterol level is usually between 20-50 mg/dL. FHBL results from mutations in APOB, PCSK9 gene. Patients with homozygous APOB-related familial hypobetalipoproteinemia (APOB-FHBL) may have symptoms of fat malabsorption, steatorrhea, diarrhea, failure to thrive, de...

A Case of Sjogren's Syndrome with systemic involvement combined with exacerbated hyperthyroidism improved after glucocorticoid treatment

Lee Donghyun , Sik Kim Heung , Yun Park So , Kang Seokjin

Background: Sjogren’s syndrome is a systemic autoimmune disease, and it is rare in pediatric population. Primary symptoms are dry mouth and dry eyes. However, it may present with systemic manifestations, involving lungs, liver, kidneys, vasculature, and blood. We report a case of Sjogren's syndrome with systemic involvement in a child with Graves' disease.Case report: A 9-year-old 11-month-old girl presen...

Factors related to permanent congenital hypothyroidism

Sik Kim Heung , Yun Park So , Lee Donghyun , Kang Seokjin

Purpose: The purpose of this study was to retrospectively analyze the clinical, laboratory, imaging findings (sonography and Tc99m-pertechnetate scanning) in patient with congenital hypothyroidism (CH) who completed 3 years of LT4 medication.Method: 86 patients with congenital hypothyroidism were retrospectively reviewed. Medical history, laboratory, radiologic finding at the time of CH diagnosis were evaluated. Correlat...

A Case with Monogenic Diabetes Caused by RFX6 Mutation in a 14-Year-Old-Girl

Kim Goo Lyeon , Kwak Soo Heon , Yu Jeesuk

Introduction: In previous times, diabetes mellitus in children and adolescents was usually type 1 diabetes which was caused by autoimmune beta cell destruction, but due to the increased prevalence of obesity, the incidence of type 2 diabetes was explosively increased in children and adolescents. The underlying mechanism of childhood-onset type 2 diabetes mellitus may be different to the adult-onset type 2 diabetes. It is worthwhile to find new causes of monoge...

Serum Nonylphenol and Obesity in Children and Adolescents

Seo Moon Young , Kim Shin-Hye , Park Mi Jung

Background: Experimental models suggest that exposure to low dose nonylphenol could induce adiposity and promote adipocyte differentiation in mice. However, studies on the effect of nonylphenol exposure to human obesity have not been adequately studied.Objective: We investigated the associations of serum nonylphenol concentration with adiposity measures in Korean children and adolescents.Me...

Renal Complication of Hematuria and Proteinuria after Recombinant Human Growth Hormone Therapy in Children

Kim Chan Jong , Park Na Ri , Yang Eun Mi

Introduction: Treatment with recombinant human growth hormone (rhGH) is useful for growth failure in short stature children. But there are some reports of renal disease or complication occurring during rhGH treatment. GH and insulin-like growth factor-1 (IGF-1), together with other growth factors and cytokines, have important roles in adaptive morphological and functional changes in the kidney. This study was aimed to reveal the renal complication of hematuria...

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...

Effect of Gonadotropin-Releasing Hormone Agonist Treatment on Final Adult Height in Boys with Idiopathic Central Precocious Puberty

Kim Eun Young , Yi Kyung Hee , Lee Jae Hee

Purpose: Central precocious puberty (CPP) is less common in boys than girls; very little data is reported on long-term effects of gonadotropin-releasing hormone analog (GnRHa) treatment in boys with CPP. The aim of the study was to evaluate the impact of treatment with GnRHa on adult height (AH) and body mass index (BMI) in boys with idiopathic CPP.Subjects and Methods: In 18 boys with confirmed diagnosis of idiopathic C...

De Novo Mutation of ABCC8 Gene in a Child with MODY Developed at 25 Months of Age

Lyeon Kim Goo , Heon Kwak Soo , Yu Jeesuk

Introduction: Recently the incidence of type 2 diabetes was explosively increased in children and adolescents. The underlying mechanism of childhood-onset type 2 diabetes mellitus may be different to the adult-onset type 2 diabetes. Therefore, it is useful to conduct genetic study in children with type 2 feature to understand underlying cause of glycemic dysregulation as well as for the management of diabetes mellitus.Case</stron...

Pure Gonadal Dysgenesis with Partial Testicular Development Associated with Turner Syndrome with SRY

Hee Yi Kyung , Kim Eun Young , Han Heon Seok

Turner syndrome is the most common chromosomal disorder in girls. They present classically short stature and delayed puberty. Turner girls with 45,X karyotype show normal female external genitalia. But Turner patients containing 45,X/46,XY mosaicism, or Sex-determining Region Y(SRY) gene may have mixed gonadal dysgenesis with various external sexual differentiation or pure gonadal dysgenesis. Existence of Y chromosome particles in Turner syndrome implies that they have risk of...
