Phenotypic and Genotypic Variability of Patients with 5-α Reductase Type 2 Deficiency

Hu Kun , Krone Nils , Kirk Jeremy

Background: Steroid 5-α reductase type 2 (SRD5A2) deficiency is an rare inherited disorder resulting from mutations in the SRD5A2 gene, causing 46,XY DSD (Disorder of Sex Development). The mutated SRD5A2 enzyme can no longer convert testosterone to dihydrotestosterone, which is needed for virilisation of external genitalia.Objective and hypotheses: To describe the phenotype, investigations and management of SRD5A2 deficiency.<p class="a...

Analysis of Genetic Mutations in a Chinese Patient Affected with Noonan Syndrome

Yang Yu , Huang Hui

Objective: The aim of this study was to detect potential gene mutation of Noonan Syndrome in a Chinese family.Methods: Patient with clinical diagnosis and parents were analyzed in this study. The analysis included medical histories, clinical analysis, and genetic tests. The PTPN11, KRAS, SOS1, RAF1, NRAS, BRAF, RIT1, SOS2, LZTR1, SHOC2, CBL, NF1 gene was sequenced to identify the pathogenic mutation responsible for the development of Noonan Syndrome by P...

Thyroid Imaging Study for the Diagnosis of Congenital Hypothyroidism with Thyroid Dysgenesis

Chun Sangwoo , Yu Jeesuk

Background: Primary congenital hypothyroidism can be classified into thyroid dysgenesis and thyroid dyshormonogenesis. Thyroid dysgenesis includes aplasia, hypoplasia, and ectopia. About one-third of ectopic thyroid is presented with congenital hypothyroidism, but sometimes it may be difficult to diagnose ectopic thyroid in infancy. Thyroid ultrasonography or scintigraphy can be used to diagnose thyroid dysgenesis, but sometimes it is hard to diagnose correctly by using one of...

Yang Yu , Xu Lei

Background: Simple obese is a worldwide public health problem. Recent studies suggested a possible relationship between obese and vitamin D deficiency.Objective and hypotheses: To discuss the relationship between 25-Hdroxyvitamin D with glucose and lipid metabolism of simple obese in Chinese children.Method: 65 children with obeses (35 mild-to-moderate, 50 severe) and sixty-two children with normal weight were enrolled in this tria...

Long-term follow-up of congenital hypothyroidism and predictors of permanent congenital hypothyroidism

Yang Jaejin , Yu Jeesuk

Purpose: Congenital hypothyroidism (CH) is a state in which thyroid hormones are insufficient at birth. This condition may last for a lifetime or may be transient. Due to the universal newborn screening test, almost all newborns are being screened for thyroid function in Korea. The study was aimed to see the predictors of transient congenital hypothyroidism with long-term follow-up of more than 3 years of CH in a single tertiary center.<...

Clinical Analysis of the Recombinant Human Growth Hormone Combined with Aromatase Inhibitors in the Treatment of Adolescent Boys with Short Stature

Wei Yu , Wu Di

Objectives: Estrogen is a key hormone to promote epiphyseal closure. So the inhibition of estrogen production can prolong the growth time of adolescent children. Therefore, aromatase inhibitors can be applied to adolescent children who has older bone age. In addition to reduction of the estrogen levels, it can promote linear growth. This study analyzed the safety and efficacy of letrozole in children for clinical reference.Method...
