Identification of Novel Mutations in FGFR1 and Functional Characteristics in Patients with Isolated Gonadotropin-Releasing Hormone Deficiency

Lee Yena , Huh Juyoung , Oh Arum , Kim Gu-Hwan , Yoo Han-Wook , Choi Jin-Ho

Background: Isolated gonadotropin-releasing hormone (GnRH) deficiency (IGD) is caused by a deficiency in GnRH production, secretion or action and a highly heterogeneous disorder with wide phenotypic spectrum including Kallmann syndrome (KS) with anosmia and normosmic idiopathic hypogonadotropic hypogonadism (nIHH). More than 30 different causative genes have been identified in several studies. FGFR1 mutations have been identified in about 3–10&#3...

Clinical and Molecular Characteristics of Pediatric Patients with Multiple Endocrine Neoplasia (MEN)

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

Purpose: Multiple endocrine neoplasia (MEN) is a rare, autosomal dominantly inherited cancer syndrome caused by a mutation in MEN1 or RET gene. Identification of the genetic causes of the MEN is critical because genotype provides information on timing of prophylactic surgery in patients with MEN type 2 who have clinically silent tumors. Therefore, this study investigated clinical phenotype and molecular characteristics of children with MEN in...

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...

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...
