Non-coding Variants in HK1 Account for 5% of Cases of Congenital Hyperinsulinism Without an Identified Genetic Cause

Rosenfeld Elizabeth , E. Boodhansingh Kara , A. Stanley Charles , Ganguly Arupa , D. De Leon Diva

Background: The genetic etiology of non-syndromic HI remains unknown in over 20% of all cases, and over 50% of diazoxide-responsive cases. Non-coding variants in HK1 have been suggested to cause HI by linkage-analysis (Pinney et al., 2008). More recently, variants within a regulatory region of HK1 intron 2 were reported in 17 individuals with HI (Wakeling et al., 2022). These variants have been proposed to cause HI by disrup...

Kenny Caffey syndrome 2; expanding the clinical spectrum

Hatziagapiou Kyriaki , Sertedaki Amalia , Dermentzoglou Vasiliki , Kanaka-Gantenbein Christina , D. Sakka Sophia

Background: Kenny–Caffey syndrome 2 (KCS 2) is a rare cause of hypoparathyroidism, characterized by proportionate short stature, cortical thickening and medullary stenosis of tubular long bones, delayed closure of anterior fontanel and eye abnormalities.Objective: We report the case of a 4-years’-old boy, who presented with the characteristic, and newly identified clinical, biochemical, radiological and genet...

Longitudinal Improvements in Health-Related Quality of Life among Children and Adolescents enrolled in Canadian Pediatric Weight Management Programs

Ybarra Marina , Rebekah Grace , D. C. Ball Geoff , Buchholz Annick , Hamilton Jill , Zenlea Ian , Morrison Katherine

Background: It is critical to understand patient-reported outcomes in pediatric patients enrolled in pediatric weight management (PWM) clinics. Health-related quality of life (HRQoL) is low in children with obesity. Utilizing data from the CANadian Pediatric Weight Management Registry (CANPWR), we examined (1) changes in HRQoL up to 3 years after enrollment in PWM and (2) factors associated with change in HRQoL over time.Methods:...

Dasiglucagon Significantly Reduces Requirement for Intravenous Glucose in Children with Congenital Hyperinsulinism ages 7 Days to 12 Months

De Leon Diva D. , Banerjee Indraneel , M Kendall David , Birch Sune , Bøge Eva , Ivkovic Jelena , Thornton Paul S

Background: Congenital hyperinsulinism (CHI) is a rare disease affecting neonates, infants, and children. CHI is characterized by dysregulated insulin secretion resulting in severe recurrent hypoglycemia. Early treatment is necessary to limit the risk of neurologic and developmental sequelae. Current treatment options are limited and inadequate. Dasiglucagon (DASI) is a glucagon analog suitable for continuous subcutaneous infusion which has been shown to raise...

Objectives: No validated achondroplasia (ACH)-specific patient reported outcome (PRO) or clinician-reported outcome (ClinRO) measures are available. A detailed review of generic PRO and ClinRO measures was performed to select relevant tools for further evaluation in a qualitative study.Methods: Published literature describing medical challenges and impacts among children with ACH was reviewed to identify important concep...

Mosaic sex chromosomal abnormalities in male individuals with short stature: a new role for non-conventional techniques (whole exome sequencing, genome wide array analysis, SHOX MLPA) in making the genetic diagnosis

Westra D. , Rinne T.K. , Oud M.S. , Ruiterkamp-Versteeg M.H.A. , de Leeuw N. , van der Velden A.A.E.M. , Kempers M.J.E.

The phenotype in male individuals with a mosaic sex chromosomal abnormality is heterogenous, but ambiguous genitalia, delayed puberty, disturbed spermatogenesis, and short stature are frequently seen. Genetic investigation in boys with idiopathic/isolated short stature usually includes SHOX gene analysis (sequencing and copy number detection by MLPA), genome wide array analysis, and/or whole exome sequencing (WES). In the Netherlands, conventional karyotyping is not part of th...

An Investigation Of Androgen-responsive Non-coding RNAs In Boys With Atypical Genitalia Without Genetic Variants in the Androgen Receptor (AR)

Alimussina Malika , McMillan Martin , Chudleigh Sandra , D McNeilly Jane , A Diver Louise , McGowan Ruth , S Tobias Edward , Faisal Ahmed S

Introduction: Recent studies point to the existence of androgen-responsive non-coding (nc) RNAs in peripheral blood mononuclear cells (PBMC) RNA.Aim: To quantify the androgen-responsive gene expression of SNORD5 and RNY5 and investigate their relationship to the testosterone (T) rise following hCG stimulation in boys with no genetic evidence of androgen insensitivity.Methods: 19 bo...

FADES: A Birth Cohort to Understand the Mechanisms Underlying Accelerated Onset of Autoimmunity in Children with Down's Syndrome

Williams Georgina , Mortimer Georgina L. , Leary Sam D. , Williams Alistair J.K. , Gillespie Kathleen M. , Hamilton - Shield Julian P.

Background and Aims: Children with Down's syndrome (DS) are at increased risk of autoimmune conditions including type 1 diabetes (T1D), coeliac and thyroid disease. We previously examined the clinical and immunogenetic characteristics of these conditions in children with DS. An earlier age-of-onset of diabetes was observed compared with children with T1D from the general population despite having decreased frequencies of the established genetic susceptibil...

Circulating miR-451a: A Biomarker to Guide Diagnosis and Treatment of Polycystic Ovary Syndrome in Adolescent Girls

Díaz Marta , Bassols Judit , López-Bermejo Abel , de Zegher Francis , Ibáñez Lourdes

Polycystic ovary syndrome (PCOS) is a prevalent disorder in adolescent girls, commonly driven by hepato-visceral fat excess, usually presenting with hirsutism and menstrual irregularity, and often followed by subfertility and type 2 diabetes.We studied the miRNA profile of adolescent girls with PCOS, and the effects of randomized treatment with an oral contraceptive (OC) or with spironolactone-pioglitazone-metformin (SPIOMET, aiming at loss of hepato-vis...

Biotine Interference in a Patient with Non-Clinic High Thyroid Hormone Levels

Ayranci Ilkay , Filibeli Berna Eroglu , Manyas Hayrullah , Dündar Bumin Nuri , Çatli Gönül

Introduction: Differential diagnosis of thyroid hormone resistance (beta) and TSHoma should be made in patients with high free thyroxine (f-T4) and free triiodothyronine (f-T3) and non-suppressed thyroid stimulating hormone (TSH) levels. The aim of this study was to present the results of etiological research in a patient with Down syndrome who was clinically euthyroid and had high levels of f-T4, f-T3, normal TSH levels.Case</st...
