The Influence of Growth Hormone Treatment on the Basal Metabolism in Prepubertal Children with Kabuki Syndrome

Remmel Robin , Schott Dina , Gerver Willem-Jan , Stumpel Constance

Background: The influence of growth hormone (GH) on the metabolism of prepubertal children with Kabuki syndrome (KS) was never investigated before. Kabuki syndrome (KS) is a rare syndrome, which is mainly characterized by mental retardation, short stature, specific facial features, obesity and hypotonia. This syndrome caused by a mutation in the KMT2D or KDM6A gene.Objective and hypotheses: In this prospective study we investigated the ...

Functional Characterization of a Novel Heterozygous Point Mutation in the Human Glucocorticoid Receptor Gene Causing Primary Generalized Glucocorticoid Resistance

Nicolaides Nicolas C , Vlachakis Dimitris , Sertedaki Amalia , Kossida Sophia , Chrousos George P , Charmandari Evangelia

Background: Primary generalized glucocorticoid resistance (PGGR) or Chrousos syndrome is a rare familial or sporadic condition caused by mutations in the hGR gene, which reduce tissue sensitivity to glucocorticoids. A new case of PGGR caused by a novel heterozygous point mutation in the hGR gene, which resulted in threonine (T) to isoleucine (I) substitution at amino acid position 556 in the ligand-binding domain of the receptor, was recently reported in a patient with an adre...

Functional Characterization of Three Novel Mutations in the IGF1R Gene

Juanes Matias , Guercio Gabriela , Marino Roxana , Berensztein Esperanza , Ciaccio Marta , Gil Silvia , Rivarola Marco A , Belgorosky Alicia

Background: IGF1R gene mutations have been associated with varying degrees of intrauterine and postnatal growth retardation, and microcephaly. We have previously reported three novel variants in the IGF1R gene: de novo p.Arg1256Ser, de novo p.Asn359Tyr and p.Tyr865Cys (ENDO 2013, OR20-2).Aim: To characterize the functional effects of the novel IGF1R gene allelic variants.Methods: In ...

Presentation, Clinical and Genetic Outcomes in a Series of Infants With Congenital Hyperinsulinism

Carroll Aoife , Gibney Brian , McDonnell Ciara , Moloney Sinead , Monavari Ardeshir , Murphy Nuala

Background: Congenital hyperinsulinism (CHI) is a rare condition but a significant cause of recurrent hypoglycaemia in infancy and childhood. Prompt recognition and appropriate management is important to avoid long-term neurological sequelae.Objective and hypotheses: To describe the presentation, clinical and genetic outcomes in a series of infants with CHI.Method: Retrospective case series of 35 patients diagnosed with CHI between...

Neonatal Hypercalcaemia Associated with Congenital Adrenal Hyperplasia

Binay Cigdem , Simsek Enver , Tekin Neslihan , Demiral Meliha

Background: Adrenal insufficiency is an important and potentially life-threatening condition, and it is also known as a rare cause of hypercalcaemia.Objective and hypotheses: Resistant hypercalcemia may be associated with hypocortisolism.Method: A 18-day-old male infant was born at 36 weeks by emergency cesarean section for fetal distress and intrauterine growth retardation. He was referred to paediatric endocrinology because of th...

Introduction: The highest prevalence of children and adolescents with obesity in Europe is observed in the south countries. This epidemic is related to unhealthy eating patterns, decreased physical activity and increased inactivity.Objective: To determine the relationship between adiposity degree and physical activity and inactivity in children and adolescents.Methods: 338 children from 6 to 8 years of age (x=11.11 years);...

Biochemical Studies in Patients with Hyperinsulinaemic Hypoglycaemia

Otaibi Hessah Al , Senniappan Senthil , Alam Syeda , Hussain Khalid

Background: Hyperinsulinaemic hypoglycaemia (HH) is characterized by the dysregulated secretion of insulin from the pancreatic β-cell. It is a major cause of severe and persistent hypoglycaemia in the newborn period. The rapid diagnosis and avoidance of recurrent episodes of hypoglycaemia are vital in preventing brain damage.Objective and hypotheses: To assess if the serum insulin measured at the time of hypoglycaemia in neonates with HH could be co...

A Novel Mutation in the NR3C2 Gene Causing Pseudohypoaldosteronism Type 1

Sertedaki Amalia , Kanaka-Gantenbein Christina , Chrousos George P

Background: Pseudohypoaldosteronism type 1 (PHA1) is a rare inherited disease characterized by mineralocorticoid resistance with subsequent salt wasting, hyperkalemia, metabolic acidosis, and elevated plasma renin and aldosterone levels.Patients and methods: We report a male newborn that presented with failure to thrive and sustained hyponatremia during his early postnatal period. He was conceived after IVF (twin pregnancy) and prematurely born by cesare...

Pseudoexon Activation in Nicotinamide Nucleotide Transhydrogenase in Two Siblings with Familial Glucocorticoid Deficiency

Chan Li , Novoselova Tatiana , Rath Shoshana , Carpenter Karen , Atkinson H , Dickinson Jan , Pachter Nick , Price G , Choong Cathy , Metherell Lou

Background: Two siblings of non-consanguineous parents presented with FGD, demonstrated by ACTH resistance with glucocorticoid but not mineralocorticoid deficiency. The proband presented at 21 months, unresponsive with hypoglycaemia (BGL 1.5 mmol/l). Endocrine evaluation subsequent to resuscitation indicated adrenal insufficiency with elevated ACTH. Hydrocortisone therapy was commenced. A sibling, 4 years younger than the proband had a short Synacthen test (SST) performed on d...

The Natural Mutant Receptor hGRαT556I Causes Primary Generalised Glucocorticoid Resistance Through Decreased Affinity for the Ligand and Impaired Interaction with the GRIP1 Coactivator

Nicolaides Nicolas C , Skyrla Eirini , Vlachakis Dimitrios , Psarra Anna-Maria G , Sertedaki Amalia , Kossida Sophia , Charmandari Evangelia

Background: Primary generalised glucocorticoid resistance (PGGR) is a rare condition characterised by tissue insensitivity to glucocorticoids owing to inactivating mutations of the hGR gene. A new case of PGGR was reported in a patient with an adrenal incidentaloma harboring a novel heterozygous point mutation in the hGR gene, which resulted in threonine (T) to isoleucine (I) substitution at amino acid position 556 of the receptor.Objec...
