Background: Congenital hyperinsulinism (HI) is a group of insulin secretion disorders with highly heterogeneous genetic aetiologies, which may significantly impact on treatment and follow-up. Genetic diagnosis is unsolved in up to 50% of the individuals, but the benefits of retesting including all the recent genetic discoveries has not been previously assessed.Aim: We examined the effectiveness of rescreening the known H...

Establishment of Clinical and Lab Algorithms for the Identification Carriers of Mutations in CYP21A2 – A Study of 768 Children and Adolescents

Meinel Jakob , Finckh Ulrich , Schuster Andreas , Haverkamp Thomas , Richter-Unruh Annette

Background: Bi-allelic mutations of CYP21A2 encoding 21-hydroxylase are the most frequent cause of congenital adrenal hyperplasia (CAH). Non-classical CAH (NCCAH) or even just hyperandrogenism may be caused by mild or mono-allelic (single) heterozygous mutations of CYP21A2. These mutations are associated either with elevated basal or ACTH-stimulated levels of 17-hydroxyprogesterone (17OHP) in blood.Objective and hypotheses: The objective of this study wa...

Background: IGF1 resistance syndrome (IGF1RS) is characterized by intrauterine and postnatal growth deficit with normal or supranormal IGF1 levels. Additional features may include intellectual deficit, microcephaly and dysmorphisms. IGF1RS may be caused by genomic or genetic defects affecting the IGF1R locus (15q26.3).Objective and hypotheses: To investigate the frequency of IGF1R mutations in a cohort of patients with pre- and/or postn...

Background: Bone involvement is described as a relevant sign in patients suffering Gaucher disease (GD).Objective and hypotheses: To analyze the long-term effect of enzyme replacement therapy on bone mineral density, a retrospective observational study was conducted in a cohort of 34 GD pediatric patients (14 males, 20 females, median age 11.3 years).Method: Lumbar spine (LS) (L2–L4, N: 34) and total body (TB) (N: 24) bone min...

High Frequency of Hypomorphic Allelic Haplotypes of the gh1 Proximal Promoter in Patients with Proportional Undergrowth and Isolated GH Deficiency

Background: Although isolated GH deficiency (IGHD) is one of the most frequent causes of postnatal proportional undergrowth, up to 85–90% of IGHD cases are still classified as idiopathic. On the other hand, previous reports identified up to 40 different GH1 proximal promoter haplotypes, some of which show hypomorphic effects, significantly reducing GH1 expression levels.Objective and hypotheses: To investigate the frequency of ...

Kenny-caffey syndrome in the neonatal period

Eduarda Caseiro Alves M , Cadete Vitoria , Marques Filipa , Carneiro Rita , Farela Neves João , Galhardo Júlia

Introduction: Kenny-Caffey Syndrome Type 2 (KCS2) is a rare autosomal dominant genetic disorder caused by variants in the FAM111A gene, leading to cortical thickening and medullary stenosis of long bones. It is characterized by primary hypoparathyroidism, electrolyte disturbances, skeletal dysplasia with delayed closure of the anterior fontanelle, hypertelorism, and short stature. Intellectual development is normal.Case Report:</...

A Novel PADI6 Variant as a Cause of Recurrent Miscarriage and Multi Locus Imprinting Disturbance within the same family

Stern Eve , Goldman Shira , De Franco Elisa , E Flanagan Sarah , Pinhas-Hamiel Orit , Regev Miriam

Background: Genomic imprinting is the process by which preferential methylation of one parental allele results in parent of origin specific expression of particular genes. Methylation is established during gametogenesis and is maintained throughout development. Alterations in any of the processes in the establishment and maintenance of methylation can lead to aberrant imprinting, which can result in either reactivation of the original silent allele or the sile...

A Case with Primrose Syndrome and What He Taught

Orman Burçe , Sezer Abdullah , Keskin Melikşah , Savaş Erdeve Şenay , Çetinkaya Semra

Introduction: Primrose syndrome was defined in 1982. It is characterized by characteristic facial appearance, macrocephaly, global developmental delay, intellectualdisability and calcification in the outer ear. It occurs with loss-of-function mutations in the ZBTB20-gene. This gene is a transcriptional gene suppressor regulator and is effective on neurogenesis, glucose homeostasis, and postnatal growth. Here, a case with Primrose syndrome will be presented.</p...

Background: The COVID-19 pandemic continues to impact healthcare overall particularly in relation to diabetes. Initial studies showed delays in emergent healthcare utilization, decreased preventative care visits, and more severe presentations of new onset diabetes. However, the pathophysiologic relationship between COVID-19 and type 1 diabetes is not yet well understood.Objectives: Our primary objective was to compare th...

Maternal and Cord Blood Metabolites Associations with Childhood Glucose Outcomes in the Hyperglycemia and Adverse Pregnancy Outcome Follow-up Study.

E. Bianco Monica , Hai My , Scholtens Denise , Josefson Jami , Lowe William , Jr

Background: Maternal triglycerides, fatty acids, and their metabolites together with sugars and metabolic intermediates may play a role in newborn outcomes. Furthermore, maternal amino acids, acylcarnitines, lipids and fatty acids and their metabolites are associated with cord C-peptide independent of maternal BMI and glycemia, highlighting the potential contribution of maternal metabolites to offspring outcomes. This study examined the associations of materna...
