Gene Dosage Changes in the GCK Gene not Detected by Sanger DNA Sequencing in Two Patients with Phenotypic MODY 2

Birkebaek Niels H. , Brusgaard Klaus

Background: Maturity onset diabetes of the young 2 (MODY2) is phenotypically characterized by elevated fasting and post-prandial blood glucose (BG) levels and no diabetes auto-antibodies. Inheritance is autosomal dominant, and it is caused by variants in the glucokinase (GCK) gene with resetting of the pancreatic glucose sensor to a higher level. It is essential to detect MODY 2 patients as they do not require treatment.Objective...

Hypothyroidism in a Child During Treatment with Nivolumab for a Glioblastoma

H Birkebaek Niels , Dahl Christine

Objective: The programmed cell death 1 protein (PD1) is a T lymphocyte membrane receptor, which when bound to its ligand PD – L1 inactivates the cytotoxic T lymphocyte, thereby down regulating the immune response. Cancer may upregulate PD – L1 on the cell surface, further downregulating the immune response. Nivolumab, a so called check point inhibitor, is a PD1 antibody, and when bound to PD1 keep the cytotoxic T lymphocyte active. Cytotoxic T lymphocyte activation b...

Idiopathic Hypoparathyroidism in a 10 Year-Old Girl with Concomitant Epilepsy, Long Q-T Syndrome (LQTS), Pericarditis and Pneumonia

Borysewicz-Sańczyk Hanna , Sawicka Beata , Kiryluk Barbara , Szumowski Piotr , Allgrove Dr. Jeremy , Bossowski Artur

Introduction: PTH is one of the principal regulatory hormones for calcium and phosphate homeostasis. Hypoparathyroidism, caused by reduced parathyroid hormone (PTH) concentration is characterised by hypocalcemia and hyperphosphataemia. Hypoparathyroidism in children can occur either as part of a genetic syndrome, autoimmune disorder, be acquired secondarily to thyroidectomy or some destructive process of the glands. If the reason for decreased PTH concentration is unknown, it ...

Pitfalls in the Diagnosis of An Infant with 46,XX DSD with Congenital Adrenal Hyperplasia due to Cytochrome P450 Oxidoreductase Deficiency – the Value of Simultaneous Genetic Analysis to the Diagnosis in DSD

Idkowiak Jan , Mohamed Zainaba , Allen Stephanie , Chandran Harish , McCarthy Liam , Kirk Jeremy , Cole Trevor , Krone Nils

Introduction: Congenital adrenal hyperplasia (CAH) is the underlying diagnosis in most newborns presenting with 46,XX disorders of sex development (DSD). Cytochrome P450 oxidoreductase deficiency (PORD) is a rare form of CAH caused by inactivating mutations in the POR gene. POR is a crucial electron donor to all microsomal type 2 P450 cytochromes (CYPs), including 21-hydroxylase (CYP21A2) and 17alpha-hydroxylase (CYP17A1). The hallmark feature of PORD is combined sex-steroid a...

A leu402pro Mutation of the Non-hla Gene il18rap in Aggressive Neonatal Type 1 Diabetes Mellitus

Dirlewanger Mirjam , Blouin Jean-Louis , Bevillard Jeremy , Santoni Federico , Schwitzgebel Valerie

Background: Neonatal diabetes mellitus is defined by severe hyperglycemia appearing before 6 months of age. It occurs in about one in 200 000 live births and most cases are known to be of monogenic origin. Classical autoimmune type 1 diabetes mellitus (DM) is exceptional in this age group.Objective and hypotheses: Recently non-HLA type 1 DM susceptibility genes, such as IL18RAP, influencing the rate of progression to diabetes among children with...

Neonatal Diabetes – the Great Masquerader: Experiences from One Hospital

Ponmani Caroline , Allgrove Jeremy , Gevers Evelien , Keane Morgan , Banerjee Kausik , Besser Rachel

Background: Neonatal diabetes can present from birth to six months of age. This can often be confused with sepsis as there is considerable overlap of symptoms in this age group as illustrated below.Objective and hypotheses: The cases described illustrate the importance of blood glucose monitoring in sick infants presenting to emergency care settings we recommend an initial check of blood glucose concentrations in all sick infants who present to Accident ...

Outcomes of the low dose short Synacthen test in infancy

Park Julie , Jones Lily , Dharmaraj Poonam , Senniappan Senthil , Morgan Colin , Hawcutt Daniel , Blair Joanne

Background: The hypothalamic-pituitary-adrenal (HPA) axis may be suppressed at birth. In most infants this is tolerated well. HPA testing in infancy often generates ‘abnormal’ results although abnormalities of the HPA may not be identified and cortisol measurements often ‘normalise’ over time.[1]Aim: To contribute to the evidence base on neonatal HPA activity by reporting outcomes of infants age &...

Report of the first paediatric case of hypercalciuric hypocalcaemia managed with simultaneous parathyroid and kidney transplantation

Oprea Alina , Jones Helen , Buck Jackie , Kessaris Nicos , D. Sinha Manish , Ware Nick , Cheung Moira

Background:Calcium-sensing receptors (CaSR) located on parathyroid glands and kidneys act to regulate serum calcium levels. Inherited hypocalciuric hypercalcaemia and autosomal dominant hypercalciuric hypocalcaemia are due to inactivating and activating CaSR mutations respectively. We present the immediate and medium term postoperative clinical course of the first paediatric patient with hypercalciuric hypocalcaemia managed with a simultaneous parathyroid and ...

Feasibility of integrating an mHealth intervention to increase exercise and physical activity adherence into a weight management service for adolescents with severe obesity: MOTIVATE-WMA

Davies Andrew , Hesketh Katie , Clarke Ellie , Apperley Louise , Sprung Victoria , Jones Helen , Senniappan Senthil , Cocks Matthew

Introduction: The Royal College of Paediatrics and Child Health state that adolescents with significant obesity require access to evidence-based weight management services (WMS). Due to the known benefits of exercise and physical activity (PA) on physiological and psychological outcomes increasing exercise and PA should form a cornerstone of any WMS for adolescents living with obesity. However, supervised exercise interventions face challenges within a clinica...

Hyperinsulinism secondary to PMM2 gene variants: a case series from a quaternary centre reporting associated inflammatory bowel disease and aortopathy.

Shaunak Meera , Bockenhauer Detlef , Flanagan Sarah , Kiparissi Fevronia , Jones Kelsey , Gilbert Clare , Morgan Kate , Dastamani Antonia

Introduction: A promoter mutation (c.167G>T) in the phosphomannomutase 2 (PMM2) gene, either homozygous or occurring in trans with a PMM2 coding mutation, causes hyperinsulinism (HI) and polycystic kidney disease (PKD) – HIPKD. Organ-specific deficiency of PMM2 leads to the restricted phenotype of HIPKD, without typical clinical features of the Congenital Disorder of Glycosylation Type 1a (CDG1a), which is caused by recessive coding ...
