Background: Woodhouse-Sakati syndrome (WSS) is a rare, autosomal recessive genetic disorder with variable clinical manifestations mainly affecting the endocrine and nervous systems. Diabetes mellitus is one endocrine manifestation but there are no comprehensive data on the epidemiology, clinical features, underlying mechanisms, and management, particularly within the Qatari population.Methods: This retrospective study wa...

Background: Obesity is highly prevalent in the MENA region, especially in children and it has been associated with neurodegeneration. We have undertaken corneal confocal microscopy (CCM) to assess for evidence of neurodegeneration in children with simple obesity and monogenic obesity (MC4R gene mutation) and further assessed the effect of glucagon-like peptide 1 agonist (GLP-1) therapy on corneal nerve regeneration.Methods:</stro...

Background: Melanocortin-2 receptor (MC2R) is a member of the G protein-coupled receptor family. MC2R is selectively activated by adrenocorticotropic hormone (ACTH); the binding of MC2R and ACTH activates the heterotrimeric G protein complex, and in turn stimulates steroidogenesis. Pathogenic variants in the MC2R gene result in glucocorticoid deficiency-1 (GCCD1), an autosomal recessive disorder in which unresponsiveness to ACTH leads to deficient secretion of cortisol and adr...

Background: Woodhouse-Sakati syndrome (WSS) is rare autosomal recessive condition characterized by progressive extrapyramidal signs, mental retardation, hypogonadism, alopecia, and diabetes mellitus. The age at disease onset, manifestation and severity of specific symptoms differs significantly among individuals with this syndrome and even among affected members of the same family. The gene C2orf37, which is responsible for WSS, located on chromosome 2q22.3-q35.<p class="a...

Background: Congenital leptin deficiency (CLD) is an extremely rare condition due to homozygous pathogenic mutations in the leptin (LEP) gene. The clinical manifestation of patients with CLD is severe early-onset obesity and hyperphagia. Most patients with pathogenic homozygous leptin gene mutations have low or undetectable leptin levels, whereas few cases show high bio-inactive circulating leptin levels. To date, around 20 variants in the LEP gene have been d...

Background: Congenital hyperinsulinism (CHI) is the most common cause of persistent hypoglycemia in infancy, characterized by unregulated insulin secretion. CHI is a challenging disease to diagnose and manage. Moreover, complicating the course of the disease with another metabolic disease like Maple syrup urine disease (MSUD) adds more challenges to the already complex management.Case: We report a term male neonate with uneventful birth ...

Introduction: Familial chylomicronaemia syndrome (FCS) is a rare autosomal recessive disorder caused by mutations in lipoprotein lipase, resulting in the accumulation of chylomicrons in plasma and therefore hypertriglyceridemia. Elevated triglycerides (TG) cause several complications, the most serious one is recurrent pancreatitis. The mainstream of management is a fat-restricted diet, followed by supplementing with Omega-3 fatty acids. Fenofibrate, and statin...

Background: Autoimmune polyglandular syndrome type 3 (APS3) comprises a wide spectrum of autoimmune endocrine disorders other than adrenal insufficiency. It includes the association of autoimmune thyroid disease (ATD) with type 1 diabetes (T1D) which is known as APS3 variant (APSA3v). Genes linked to possible joint susceptibility for APS3v have been reported in few cases. We report a 10-year-old girl with Graves’ disease (GD) who developed T1D after 6 years of the diagnos...

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...

Introduction: Mendelian diseases are rare individually but collectively are estimated to affect more than 5% of global population with more than 6000 different rare phenotypes including monogenic forms of diabetes. The proportion of individuals who possess a particular genotype and exhibit the expected phenotype is defined as the penetrance of that genotype. If everyone with the genotype presents with clinical symptoms by a particular age, then it is said to b...
