Association between Estrogen Receptor Gene Polymorphisms and Premature Thelarche

Yoon Jong Seo , Lee Hae Sang , Lim Jung Sub , Hwang Jin Soon

Background: Premature thelarche (PT) is a benign, non-progressive condition defined as isolated breast development without the activation of the hypothalamic-pituitary axis. While the pathophysiology of PT remains unclear, increased sensitivity to estrogen may cause PT.Objective and hypotheses: The aim of this study was to investigate the association between polymorphisms in the estrogen receptor alpha (ERĪ±) gene and PT in girls.<p class="abstex...

Gonadal and Sexual Dysfunction in Childhood Cancer Survivors

Yoon Ju Young , Park Hyeon Jin , Chung Jin Soo , Hwang Sang Hyun , Lee Dong Ock , Shim Hye Young , Park Byung Kiu

Background: Gonadal or sexual dysfunctions are common and important complications of childhood cancer survivors. But few studies have been conducted on these areas, and if any, they are only about gonadal dysfunctions. Semen quality or sexual functions were rarely investigated.Objective and hypotheses: We purposed to evaluate prevalence of gonadal failure, semen abnormality, and sexual dysfunction of adolescent/young adult childhood cancer survivors. Ris...

Analysis of hypothyroidism NGS test in Korean patients with congenital hypothyroidism in a single center

Jung So Yoon , Lee Jeongho ,

Introduction: Thyroid hormone is known as greatly influence on growth and development in fetuses and newborns. If the detection of the disease is delayed, hypothyroidism can cause irreversible damage, so early detection and treatment is very important. Hypothyroidism can be divided into permanent and temporary cases depending on the duration of treatment, but there is no predictor that can completely differentiate those two. However, as genes related to hypoth...

Growth Outcome in Girls with Idiopathic Central Precocious Puberty Treated with Gonadotropin-releasing Hormone Agonist

Sang Lee Hae , Hwang Jin Soon

Objective: Gonadotropin-releasing hormone agonists (GnRHa) are the treatment of choice for central precocious puberty (CPP) and have been widely used for decades. We determined the effect of GnRHa treatment on auxological outcomes of girls with idiopathic CPP.Methods: This study included 84 girls treated monthly with depot leuprolide acetate who had reached adult height. We compared their final adult height (FAH) with their initial predicted adult height...

Whole-exome Sequencing Identifies Novel Pathogenic Variants in Korean Families with Central Precocious Puberty

Lee Hae Sang , Hwang Jin Soon

Objective: Central precocious puberty (CPP) is characterized by the development of secondary sexual characteristics before the age of 8 years in girls and 9 years in boys. Early activation of hypothalamic-gonadal axis is influenced by both environmental and genetic factors. Especially, genetic factors have critical role of pubertal progression, but mutations associated with CPP have only been discovered in three genes: KISS1, KISS1R, and MKRN3. The aim of thi...

GX-H9 is a long-acting form of recombinant human GH under clinical development for both adults and children with GH deficiency (GHD). This study was designed to compare 12-month effects of once-weekly and twice-monthly (every other week; EOW) administration of GX-H9 treatment to that of Genotropin®, in pediatric patients with GHD. A randomized, open-label, active-controlled, parallel study was conducted at 27 endocrinology centers in 10 countries (Europe and Ko...

Response of GH Therapy in Six Children with Achondroplasia

Kim Yoon Jung , Cho Byung Wook , Kim Ji Yoon , Kim Heung Sik , Lee Hee Jung

Background: Achondroplasia is the most common condition characterized by disproportionate short stature. Patients with achondroplasia progressively fall below normal standards for length and height. GH has been widely used to treat short stature with or without GH deficiency (GHD).Objective and hypotheses: The purpose of the present study was to clarify the effectiveness of GH therapy on short stature in achondroplasia.Method: The ...

A rare case of childhood hypophosphatasia presenting with fibrous dysplasia

Jeon Jaesung , Lee Jun , Young Yoon Ju , Kun Cheon Chong

Objectives: Hypophosphatasia (HP) is a rare inherited disorder characterized by defective bone and teeth mineralization, and deficiency of serum and bone alkaline phosphatase activity. The symptoms are highly variable in their clinical expression, which ranges from stillbirth without a mineralized bone to early loss of teeth without bone symptoms. We aimed to report a patient with HP presenting with fibrous dysplasia.Methods:</st...

The mutation of the FGFR3 gene causes familial acanthosis nigricans with hypochondroplasia syndrome

Sang Lee Hae , Suk Shim Young , Sub Lim Jung

Objective: Acanthosis nigricans (AN) is characterized by velvety and papillomatous pigmented hyperkeratosis of the flexures and neck. Mutations in fibroblast growth factor receptor 3 (FGFR3) gene have been identified as one of the causes of skeletal dysplasia with AN. However, there have been few reports about familial AN with hypochondroplasia. Here we report a familial case with FGFR3 gene mutation.Case reports: A 16-y...
