A Uniquely Mild Presentation of Hyperinsulinemic Hypoglycemia Due to a HADH Mutation (c.709+39C>G) Not Treated with Diazoxide: Long Term Clinical Course

Abdulhadi-Atwan Maha , Flanagan Sarah , Houghton Jayne

Short-chain L-3-hydroxyacyl-CoA (SCHAD, HADH) deficiency is characterized by diazoxide-responsive hyperinsulinemic hypoglycemia in the neonatal or infancy periods. These patients have severe protein (especially leucine) sensitivity. HADH mutations are recessively inherited with less than 50 patients reported so far. The mechanism behind unregulated insulin secretion in SCHAD deficiency is not understood but may involve changes in protein-protein interactions with glutamate deh...

Mortality in children with monogenic diabetes

Globa Eugenia , Zelinska Natalia , Franco Elisa De , Houghton Jayne , Johnson Matthew , Ellard Sian ,

Background: In this study we investigated mortality in children with monogenic diabetes.Methods: Within the Ukrainian Pediatric Diabetes Register (UPDR) the number of children with type 1 diabetes mellitus (DM1) 0-17 y.o. in 2019 was 9860 (1 in 769), with DM2 - 36 (1 in 210,547) with neonatal DM (NDM) - 66 (1 in 115,000), with MODY - 40 cases (1 in 114,844). We used targeted next generation sequencing (tNGS) of all known...

Different Potent Glucocorticoids, Different Routes of Exposure but The Same Result: Iatrogenic Cushing's syndrome and Adrenal Insufficiency

Güven Ayla

Background: Cushing's syndrome (CS) is very rare in children and the most common cause is the high doses of glucocorticoids (GC) administered. It is well known that application of potent GCs cause iatrogenic CS (ICS) due to suppressing hypothalamo-hypophyseal-adrenal (HPA) axis and later even adrenal insufficiency (AI). Other side effects of GCs are also seen in these patients.Objective: The aim of this study is to r...

Salt-Wasting CAH phenotype as a result of the TNXA/TNXB Chimera 1 (CAH-X CH-1) and the severe IVS2-13A/C>G in CYP21A2 gene

Fanis Pavlos , Skordis Nicos , A Phylactou Leonidas , Neocleous Vassos

Background: Genetic diversity of mutations in the CYP21A2 gene is the main cause of the monogenic Congenital adrenal hyperplasia (CAH) disorder. On chromosome 6p23.1, the CYP21A2 gene is partially overlapped by the TNXB gene and reside in tandem with their highly homologous corresponding pseudogenes (CYP21A1P and TNXA), which leads to recurrent homologous recombination.Methods and Results: The genetic s...

IPEX Syndrome Caused by A Novel Mutation in Foxp3 Gene: A Case Report

Bich Ngoc Can Thi , Chi Dung Vu , Phuong Thao Bui , Ngoc Khanh Nguyen , Thanh Mai Do Thi , Johnson Matthew , De Franco Elisa , Ellard Sian

Background: Immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome is a rare and life-threatening primary immunodeficiency characterized by widespread autoimmunity. Mutations in the FOXP3 gene have been identified as the cause for IPEX syndrome.Objective and hypotheses: To describe clinical characteristics and genetic finding in the first Vietnamese patient with mutation of FOXP3 gene.Meth...

Neonatal Hyper- and Hypoglycaemia; Widening the Clinical Phenotype of Transient Neonatal Diabetes Mellitus due to 6q24 Methylation Defects

Taylor-Miller Tashunka , O'Connell Michele , Sabin Matthew

6q24 methylation defects are the most common cause of Transient Neonatal Diabetes Mellitus (TNDM). The clinical picture is one of impaired insulin secretion, small for gestational age and diabetes mellitus aged <6 months. This case illustrates the fluctuation between both hyper- and hypoglycaemia that can been seen in 6q24 methylation defects. A term, small for gestational age baby boy was noted to have hypoglycaemia (BSL 1.8 mmol/l) at 1.5 h of life which resolved with or...

Introduction: DAX1 (NROB1) mutation, that is among the causes of primary adrenal insufficiency; is revealed with X-linked congenital adrenal hypoplasia and hypogonodotropic hypogonadism. Growth hormone (GH) deficiency is not common in affected individuals. In the literature, there are few cases of GH treatment . growth hormone therapy in two cases with DAX1 gene mutation were evaluated in clinical features and treatment responses.<strong...

Idiopathic Infantile Hypercalcemia: Mutations in SLC34A1 and CYP24A1 in Two Siblings and Fathers

Güven Ayla , Konrad Martin , Schlingmann Karl Peter

Background: Both CYP24A1 and SLC34A1 gene mutations are responsible for idiopathic infantile hypercalcemia (IIH). Whereas loss-of-function mutations in CYP24A1 (25-OH-vitamin D-24-hydroxylase) lead to a defect in the inactivation of active 1,25(OH)2-vitamin D3, mutations in SLC34A1 encoding renal sodium-phosphate co-transporter NaPi-IIa lead to primary renal phosphate wasting combined with an inappropri...

Objective: We aimed to investigate the usefulness of abdominal adiposity and total body fat as predictors of cardiometabolic health, especially insulin sensitivity, in children and adolescents.Methods: Participants were 479 children and adolescents with obesity (322 boys and 157 girls) aged 3 to 18 years attending the Children's Hospital at Zhejiang University School of Medicine (Hangzhou, China). Participants underw...

Increasing Lean Body Mass, Phase Angle, and Total Body Water But Decreasing Body Fat Among Short-statured Children Born Small-for-Gestational Age on GH Treatment

Volkl Thomas M K , Stumpf Isabel , Dorr Helmuth-G

Background: There is a small proportion of children born SGA without postnatal catch-up growth who are presented with persistent short stature, low BMI, and decreased lean body mass (LBM). Data on body composition are rarely reported in the literature. Our study addresses the question whether human recombinant GH treatment could affect body composition in these SGA children or not.Design: We included 58 SGA children (n=20 females) with SGA (birt...
