Context: Neonatal hypoglycemia due to congenital hyperinsulinism (CHI) is a potentially life-threatening condition. Severe forms of CHI, caused by autosomal recessive variants in KATP channel subunit genes (ABCC8, KCNJ11), are more prevalent in regions with high consanguinity. These regions also have a high neonatal mortality rate with many deaths remaining unexplained.Patients and Methods: We analyze...

Introduction: The main type of diabetes seen in pediatric clinical practice is type 1 diabetes. Monogenic diabetes and syndromic diabetes are rare, but can be more common in areas where consanguinity is high.A 12-year-old girl born to consanguineous parents who are first cousins, was referred after being diagnosed with diabetes and severe diabetic ketoacidosis. In addition, she had hypertrichosis, coarse facial features, acanthosis nigri...

Introduction: Statural growth is regulated by multiple genetic, epigenetic and environmental mechanisms. The GH-IGF-1 axis was long believed to be the main linear growth regulator in children until more recent studies showed that the complex regulation of growth plate chondrocytes play an equal role. In order to extend our knowledge about the genes involved in short stature, we studied a unique cohort of children with short stature from consanguineous families...

Introduction: Linear growth is a complex process involving the interplay of genetic, epigenetic, and environmental factors. Current knowledge sheds importance to the GH-IGF-1 axis, chondrocyte regulation and extra-cellular matrix in the growth plate, and other fundamental intracellular processes. Despite these advancements, the genetics of short stature are not fully understood. This study aims to contribute by investigating a unique cohort of children from co...

Introduction: The ZSWIM6 gene was first described with a unique de-novo heterozygous variant causing acromelic frontonasal dysostosis, characterized by craniofacial, brain, and limb malformations. Another de-novo heterozygous variant was later described causing severe intellectual disability, hypotonia amd seizures but without craniofacial or limb malformations. These findings suggest a clear genotype-phenotype correlation for ZSWIM6. Gene in...

Introduction: Monogenic diabetes has been estimated to be 1 - 6% of all diabetic cases in European countries which are primarily non consanguineous populations, while the incidence in highly consanguineous areas is insufficiently defined. However, the genetic aetiology of monogenic diabetes has been shown to be widely different in areas with prevalent consanguinity compared to areas with lower rates. In this single-centre study, we aimed to evaluate the preval...
