Background: Beckwith Wiedemann syndrome (BWS) is an overgrowth disorder with vari-able phenotype (hemihypertrophy, macroglossia, visceromegaly, malformations, and hypo-glycaemia in 30–50%) and predisposition for tumors, during the second part of pregnancy and first few years of life.Objective and hypotheses: Molecular characterisation of a patient with BWS was perfor-med to ensure adequate clinical management. This analysis revealed the most common ...

Background: Cholestatic hepatopathy is a rare but serious threat to neonates and young infants. Their immature hepatic excretory function predisposes for severe and rapidly progressive hepatic injury. Because of the wide range of possible etiologies, it is often difficult to make an accurate diagnosis. One rare endocrine cause can be primary or secondary hypocortisolism.Case presentation: i) A 7-week-old term-born female with cholestasis, elevated liver ...

Background: Congenital hyperinsulinism of infancy (CHI) is the most common cause for persisting hypoglycaemia in infancy. Genetic causes are mutations in ABCC8 or KCNJ11 (coding for K+ATP-channel subunits), less frequently mutations in GCK or GLUD1. Further genetic examinations are usually performed only if phenotypic aspects point to other specific genes, such as the rare short chain 3-hydroxylacyl-CoA dehydrogenase (<...

Background: Kabuki syndrome (KS) is a rare multiple congenital malformation and intellectual disability syndrome. KS is caused by pathogenic variants in the genes KMT2D or KDM6A. In 0.3-4% of patients, KS is reported to be associated with hyperinsulinemic hypoglycemia. The objective of this study was to characterize the clinical, biochemical and molecular data of children with KS and hyperinsulinemic hypoglycemia.<s...

Background: Transient neonatal diabetes (TNDM) is commonly caused by a methylation loss in the 6q24 region, either in isolation or as multiple-loci demethylation due to ZFP57 gene mutation. TNDM is biphasic; usually resolves after 2–3 months but often recurs between age 4 and late adolescence.Case: The boy was born at 38 weeks of gestation (birth weight 3340 g, healthy consanguineous Turkish parents, unremarkable pregnancy). He presented at...
