Nonautoimmune Neonatal Hyperthyroidism due to A633G Mutation in the Thyrotropin Receptor Gene

Jung In Ah , Cho Won Kyoung , Jeon Yeon Jin , Chae Hyo Jin , Kim Myung Shin , Suh Byung Kyu

Background: Congenital hyperthyroidism is a rare disease. In most patients with congenital hyperthyroidism are autoimmune forms caused by maternal thyroid-stimulating antibodies. In contrast to autoimmune hyperthyroidism that is transient, nonautoimmune form of congenital hyperthyroidism is persistent and results from activating germline mutations in the thyrotropin receptor (TSHR) gene.Case presentation: We report the case of a Korean male infant with s...

Objective: Ketosis-prone diabetes (KPD), characterized by presentation with diabetic ketoacidosis (DKA) in patients lacking the typical features of autoimmune type 1 diabetes, is a heterogeneous syndrome. The objective of this study is to ascertain the presence of A-β+ (autoantibody-negative, β-cell functional reserve) KPD in Korean children and adolescents and to study their characteristics in this group. Method: Diabetes ...

HLA Alleles and Amino Acid Variants of HLA-A, -B, -C, -DRB1, -DQB1, -DPB1 Molecules in Early-Onset Autoimmune Thyroid Disease

Cho Won Kyoung , Shin Dong Hwan , Kim Seul Ki , Lee Seonhwa , Choi Yujung , Ahn Moonbae , Baek In Cheol , Jung Min Ho , Kim Tai-Gyu , Suh Byung-Kyu

Objective: We try to investigate the polymorphisms and amino acid variants of HLA-A, -B, -C, -DRB1, -DQB1, -DPB1 molecules in early-onset AITD.Methods: The genotypes of HLA-A, B, C, DRB1, DQB1, and DPB1 on AITD were analyzed in 102 Korean children with AITDs (Graves’ disease (GD)=62, Hashimoto’s disease (HD)=40) and 142 healthy control using sequence-based typing. Analysis of variant amino acids was performed across the genotyping results with ...

Kim Shin-Hee , Ahn Moon Bae , Cho Won Kyoung , Cho Kyoung Soon , Park So Hyun , Jung Min Ho , Suh Byung-Kyu

Background: Central precocious puberty (CPP) may result from organic lesions, but it is most frequently of idiopathic origin in girls.Objective and hypotheses: The objective of the study was to identify central nervous system abnormalities in girls with CPP.Method: This retrospective study was performed in 3-tertiary care hospitals between 2005 and 2015. During this period, 200 girls with CPP performed brain magnetic resonance imag...
