Transient Hyperinsulinaemic Hypoglycaemia in Association with a Novel ABCC8 Mutation: Expanding the Clinical Phenotypes

Arya Ved Bhushan , Aziz Qadeer , Mohamed Zainaba , Flanagan Sarah E. , Ellard Sian , Ehtisham Sarah , Tinker Andrew , Hussain Khalid

Background: Hyperinsulinaemic hypoglycaemia (HH) can be transient or permanent. Transient HH (spontaneous resolution of HH within few weeks) is associated with intrauterine growth restriction, maternal diabetes, erythroblastosis fetalis etc. Transient HH has not been reported with ABCC8/KCNJ11 mutations, which are the commonest cause of HH.Aim: Molecular characterisation of a novel ABCC8 mutation associated with a transient HH phenotype seen in a family ...

Congenital Hyperinsulinism Caused by a Combination of Novel Heterozygous ABCC8 and KCNJ11 Mutations

Rozenkova Klara , Nessa Azizun , Obermannova Barbora , Dusatkova Lenka , Dusatkova Petra , Sumnik Zdenek , Lebl Jan , Hussain Khalid , Pruhova Stepanka

Background: Congenital Hyperinsulinism (CHI) is a common cause of persistent hypoglycaemia in the neonatal and infant period. It is most commonly caused by mutations in one of the KATP channel subunits, either SUR1 encoded by the gene ABCC8 or Kir6.2 encoded by the gene KCNJ11. Patients carrying mutations in the ABCC8 and KCNJ11 genes simultaneously have not been reported yet.Objective and hypotheses: Our aim was to describe the clinical pheno...

Background: Congenital Hyperinsulinism (CHI) is a heterogeneous genetically determined condition that is characterised by unregulated secretion of insulin from pancreatic β-cells. The most common and severe cases are caused by mutations in the ABCC8 gene encoding the SUR1 subunit of the KATP channel subunit. To assess the pathogenic effect of novel ABCC8 mutations we performed in-vitro functional studies.Objective and hy...

Discontinuation of Diazoxide Therapy in Children with Hyperinsulinaemic Hypoglycaemia with no Identified Genetic Aetiology: a Long-term Follow-up Study

Al Yahyaei Mouza , Shah Pratik , Guemes Maria , Gilbert Clare , Morgan Kate , Flanagan Sarah , Ellard Sian , Hussain Khalid

Background: Congenital hyperinsulinism (CHI) is a cause of severe persistent hypoglycaemia in children. Diazoxide is the first line medical therapy for CHI; however diazoxide is usually ineffective in CHI with KATP channel gene mutations. Patients with no mutations in the KATP channel genes do respond to therapy with diazoxide. There are no previous studies assessing how long diazoxide therapy is needed in those patients with no genetic aetiology identifi...

Early Corneal Nerve Loss in Children with Melanocortin 4 Receptor (MC4R) Gene Mutation Related Obesity

Gad Hoda , Dauleh Hajar , Pasha Maheen , Omer Idris , Al-Barazenji Tara , Alshafai Mashael , A. Hendaus Mohamed , A. Malik Rayaz , Hussain Khalid

Background: Obesity is highly prevalent worldwide, particularly in the MENA region. Whilst simple obesity has a variable genetic and environmental basis, syndromic and non-syndromic monogenic obesity has a strong genetic component. Melanocortin 4 receptor (MC4R) mutations are the commonest cause of monogenic obesity. MC4R also regulates neuropathic pain pathways via JNK signaling after nerve injury.Methods: Five children...

Familial Chylomicronaemia Syndrome; A Challenging Condition in Pre-School Aged Children.

Alsaffar Hussain , Al-Battashi Sultan , Al-Kindi Fatima , Al-Shidhani Azza , Al-Farsi Nouf , Al-Rawahi Yusriya , Al-Waili Khalid

Introduction: Familial chylomicronaemia syndrome (FCS) is a rare autosomal recessive disorder caused by mutations in lipoprotein lipase, resulting in the accumulation of chylomicrons in plasma and therefore hypertriglyceridemia. Elevated triglycerides (TG) cause several complications, the most serious one is recurrent pancreatitis. The mainstream of management is a fat-restricted diet, followed by supplementing with Omega-3 fatty acids. Fenofibrate, and statin...

Vosoritide Therapy in Children with Achondroplasia: Single-Center Experience

Amin Rasha , Ben-Omran Tawfeg , Khalifa Amel , Mohammed Elwaseila , Dauleh Hajar , Chirayath Shiga , Mohamadsalih Ghassan , A.Eyalawwad Ayah , Hussain Khalid

Background: Achondroplasia, the most prevalent skeletal dysplasia in children, is a multisystemic disease resulting from a common mutation in the fibroblast growth factor receptor 3 (FGFR3) gene. This mutation disrupts endochondral ossification, leading to disproportionate short stature. Historically, management has been primarily supportive due to the absence of targeted therapies. However, recent advancements have led to clinical trials for potential treatme...

Background: Paragnagliomas and pheochromocytomas are rare neuroendocrine tumors that originate from the paraganglionic cells of the autonomic nervous systems. These tumors may be extra or intra-adrenal in site. The use of antihypertensive medications is usually challenging in these patients. Long acting alpha and beta blockade can be quite useful preoperatively but challenging postoperatively. We present a case of familial paraganglioma that was successfully t...

A Novel Mutation in Eukaryotic Translation Initiation Factor 2 Subunit 3 (EIF2S3) is Associated with X-Linked Hypopituitarism and Glucose Dysregulation

Gregory Louise C. , Williams Hywel , Rahman Sophia , Ferreira Carolina B. , Alatzoglou Kyriaki S. , Kapoor Ritika R. , Hussain Khalid , Gaston-Massuet Carles , Kelberman Daniel , Qasim Waseem , Dattani Mehul T.

Background: A mutation in EIF2S3 (NM_001415; Xp22.11) was previously associated with microcephaly and developmental delay in a single pedigree. EIF2S3 encodes the eukaryotic translation initiation factor 2 subunit 3 (eIF2γ), the largest of three EIF2 subunits. EIF2 initiates protein synthesis by forming a ternary complex with GTP and initiator methionyl-tRNA which then binds to the 40S ribosomal subunit, enabling scanning of mRNA from the 5′ end to...
