Introduction: Juvenile Paget's Disease(JPD) is an extremely rare disease of bone characterized by progressive painful bone deformities, fractures and increased bone turnover. Findings also include deafness, loss of vision, vascular calcification and aneurysm. Here, we report two siblings presented with recurrent fractures and diagnosed as JPD by very high alkaline phosphatase levels and radiographic findings. A novel homozygous mutation in the TNFRSF11B g...

Introduction: Genetic factors play an important role in determining individual susceptibility to weight gain and obesity. In the last few years, several genetic variants have been identified as monogenic forms of obesity. Among them, Leptin (LEP) and its receptor on hypothalamic neurons (LEPR) are key players in the regulation of body weight, food intake and energy homeostasis. Pathogenic variants in the LEPR gene cause severe childhood-onset obesity with an a...

Introduction: Increased frequency of Grave’s disease (GD) has been reported both in adults and youth during the COVID-19 pandemic. Aim: To compare the frequency of GD prior and during the COVID-19 pandemic.Methods: Retrospective analysis of children diagnosed with GD over the last 13 years in our Department.Results: A total of 22 children (31.8% boys) with a mean age of 10.55...

Prader Willi Syndrome (PWS) is a rare neuro-genetic disorder inherited as a result of lack of expression in 15q11-13 gene and 70% are paternally inherited. Characteristic features are dysmorphism, behavioural problems, infantile hypotonia, short stature, hypothalamic dysfunction, hyperphagia and morbid obesity. The long-term morbidity and mortality depend on hypothalamic dysfunction and obesity. While multidisciplinary care is essential, growth hormone (GH) is a recognized...

Background: Advances in the treatment of childhood and adolescence cancer treatment have led to significant increase in survival rate. Current 5-survival rate of childhood cancer is nearly 80%. Hematopoietic stem cell transplant (HSCT) is treatment of choice in many clinical conditions including malignant and non-malignant hematological diseases, solid tumors and immunodeficiency diseases. Children receiving HSCT are prepared with different pre-transplant cond...

Introduction: Mayer-Rokitansky-Kuster-Hauser Syndrome (MRKH) is a congenital disorder characterized by agenesis or aplasia of the uterus and upper portion of the vagina in females with a normal karyotype (46,XX). Its incidence is approximately 1 in 4,000 to 5,000 live female births. The etiology of MRKH syndrome is highly complex and remains unclear, although genetics is believed to play a significant role in its pathogenesis.Cas...

Background: The molecular genetics of isolated hypogonadotropic hypogonadism (IHH) has been a subject of interest and recent discoveries. Multiple genetic variants with x-linked and autosomal inheritance are involved in the regulation of the hypothalamic pituitary gonadal axis.Objective and hypotheses: We undertook an extensive genetic evaluation to elucidate a possible genetic aetiology in two brothers with clinical and biochemical evidence of IHH. We h...

Obesity is a state of imbalance between food intake and energy expenditure leading to a positive energy balance. This condition may be due to the existence of a genetic syndrome: the Prader-Willi syndrome (PWS) is the genetic cause the most common obesity and Laurence-Moon Bardet-Biedl syndrome (BBS), autosomal recessive.Objectives: Our objective is to compare the cardio-metabolic risk factors in children with obesity gene to those of ch...

Introduction: Congenital adrenal hyperplasia (CAH) is a disorder with a wide spectrum of severity. Impaired cognition has been reported in patients with CAH, although the findings have been conflicting. It has been hypothesized that the major causes of the deficits are prenatal hormonal imbalances and/or excessive glucocorticoid treatment.Objective: The objective of this study was to investigate cognitive function in chi...

Background: Congenital hyperinsulinism in infancy (CHI) is the most frequent cause of persistent hypoglycemia in infants. The most common and severe form of monogenic CHI is caused by inactivating mutations in ABCC8 and KCNJ11 genes located on chromosome 11p15.1. On the ABCC8 gene; previous studies have shown that mutations were reported to be mostly localized in exon 28. There is no sufficient research in Egyptian population about different mutations in conge...
