Introduction: The MODY diabetes (Maturity Onset Diabetes of the Young) belongs to monogenic alterations group, the mutation of the gene HNF-1α is the most common and present an autosomal dominant inheritance that causes dysfunction of the Beta pancreatic cell and alteration in the reabsorption of glucose to renal level, with age of variable presentations, it often leads to a misdiagnosis as type 1 diabetes mellitus.Description of the clinical case: ...

Obesity—defined as excess fat mass which impacts on physical health—is a complex and multifactorial disease where numerous environmental factors (overeating and/or reduced physical activity) act in concert with genetic factors. Understanding molecular mechanisms of obesity has rapidly improved in recent years due to the development of faster, more specific genetic screening tools (1). Rare genetic obesities are distinguished from more-common polygenic obesities where...

We report the case of a 19 years old male patient suffering from a multisystem disease involving of the skeleton, connective tissue, immune system, brain and endocrine system due to compound-heterozygote mutations in the NBAS (Neuroblastoma amplified sequence) gene (c.5741G>A [p.(Arg1914His)]; c.6565_6566insT [p.(Glu2189Valfs*7)]), detected using whole-exome-sequencing. He has an immunodeficiency including decreased CD4+T-cells, B-cells and NK-cells with expanded ...

Background: Steroid responsive encephalopathy with autoimmune thyroiditis (SREAT) is a clinically and electrographically heterogeneous steroid-responsive encephalopathy associated with thyroid autoantibodies.Objective and hypotheses: To investigate, whether children and adolescents with Hashimoto’s Thyroiditis (HT) lacking acute clinical manifestation of SREAT show electroencephalogram (EEG) alterations, and to compare EEGs of HT patients with those...

Introduction: Hyperinsulinaemic Hypoglycaemia (HH) is one of the commonest causes of hypoglycaemia in infancy. It is characterised by hypoketotic, hypofattyacidaemic and hyperinsulinaemic hypoglycaemia. The molecular basis of HH includes defects in pathways that regulate insulin release; to date, 12 genes have been associated with monogenic forms of HH (ABCC8, KCNJ11, GLUD1, GCK, HADH1, UCP2, MCT1, HNF4A, HNF1A, HK1, PGM1, PMM2). However, no genetic aetiology has been...

Background: Transient hypothyroxinaemia of prematurity (THOP), defined as low levels of FT4 without the expected TSH surge, may concern up to 50% of infants born <30 weeks’ gestational age. Most studies showed a link between THOP and impaired neurodevelopment, as shown in the review of Eerdekens. Data about the benefit of supplementation are scarce, with few randomised trials and inconclusive results. To date, there are no clear recommendations regard...

Background: Gender differences in sex steroids and IGF1 are well known from pubertal years into adulthood. Few studies report data from pre-school years.Objective and hypotheses: To study gender specific changes in sex steroids and IGF1 at birth and at 5 years of age and correlate these with auxological measurements. There are gender differences in IGF1 levels due to differences in sex steroids already at birth and during pre-school years.<p class="a...

Objective: To evaluate growth in patients with classical CAH.Patients and methods: Retrospective, longitudinal and multicentric study of patients with classical CAH due to 21-hydroxylase deficiency who had achieved adult height(AH).Excluded: boys with simple virilising forms(SV)>1-year at diagnosis. Normative Control Group:Millennials Longitudinal Growth Study(2018). According t...

Introduction: CFTR-modulating therapy aims to restore CFTR function. It improves lung function and quality of life in CF patients however, its effects on glucose metabolism are not yet well defined.Methodology: Retrospective and longitudinal study.Inclusion criteria: patients with CF genetic diagnosis ≥10 years old on modulator therapy (ivacaftor + lumacaftor or ivacaftor + teza...

Introduction: Type 5 monogenic diabetes is an autosomal dominant disease due to a mutation in HNF1beta gene. This gene is expressed predominantly in kidney and pancreas, thus clinical manifestations are characterised by renal abnormalities and diabetes.Objectives: To review the clinical characteristics of patients who were diagnosed with type 5 monogenic diabetes in the Pediatric Endocrinology Unit of a tertiary referral hospital.<p class="a...
