Background: Duplication of the long arm of chromosome 4 has been described in more than 60 patients. The severity and specificity of associated symptoms depend on the size and location of the duplication, and which genes are involved.Reported features include developmental delay, intellectual disability, birth defects, hypotelorism, growth retardation, short neck, dysmorphism, and abnormalities to the extremities.Objective: To report a two-year old child...

Background: Fanconi Bickel syndrome (FBS) is a rare form of glycogen storage disease (GSD) inherited in an autosomal recessive manner and caused by mutations in the SLC2A2 gene leading to the loss of GLUT2 glucose transporter expression. The disease is considered to be rare in which a little more than 100 cases have been reported in the literature. The SLC2A2 gene encodes for GLUT2, a low affinity facilitative glucose transporter expressed in critical tissues ...

Background: Recurrent episodes of ketoacidosis with or without hypoglycemia have been reported with homozygous or heterozygous mutations in the solute carrier family 16 member 1 (SLC16A1) gene. This gene encodes for the monocarboxylate transporter 1 (MCT-1) which plays a key role in lactate, pyruvate and ketone body transport.Objective(s): To describe the youngest patient with a novel SLC16A1 gene who presented with recurrent episodes of ketoacidosis and...

Background: Mutations in the SLC2A2 gene are implicated in Fanconi-Bickel syndrome (FBS). This is a rare form of glycogen storage disease (GSD) inherited in an autosomal recessive manner characterized by hepato-renal glycogen accumulation, impaired glucose and galactose utilization, and proximal renal tubular dysfunction. The world-wide frequency of Fanconi-Bickel syndrome is not known, though the disease is considered to be rare in which a little more that 100 cases ...

Background: There are few reports describing proximal deletions of chromosome 20p, making it difficult to predict the likely consequences of the deletion in this area. One report has described a proximal 20p11.2 deletion associated with panhypopituitarism, craniofacial dysmorphism, a small phallus with a semi bifid scrotum, and bilateral widely separated first and second toes. The only other report has demonstrated neurodevelopmental abnormalities associated with band 20p11.2 ...

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...

Context: Monogenic obesity (MO) is a rare form of obesity due to pathogenic variants in genes implicated in the leptin-melanocortin signaling pathway and accounts for around 5% of severe early-onset obesity. Mutations in the MC4R and Leptin genes are the commonest causes of MO. Determining the genetic causes has important clinical benefits as novel therapeutic interventions were developed for some forms of MO.Objective:<...

Background: Childhood obesity is highly prevalent in the MENA region and may be associated with sub-clinical neuropathy.Methods: Children with obesity with normal glucose tolerance (NGT), impaired glucose tolerance (IGT) and Type 2 diabetes Mellitus (T2DM) and healthy controls (HC) underwent body composition analysis, assessment of vibration perception threshold (VPT), monofilament sensitivity and corneal confocal micros...
