Background: Alström syndrome is a rare genetic disorder characterized by retinal degeneration, hearing loss, early-onset obesity, type 2 diabetes, cardiomyopathy, systemic fibrosis and progressive multi-organ failure. Our aim is to present two siblings who were diagnosed in early childhood.Case presentation: Three years five months old female and her two years one month old sister admitted to paediatric neurology department due to lack of eye contac...

Background:Mutations of insulin receptor gene (INSR) lead to a wide spectrum of inherited insulin resistance syndromes. Type A insulin resistance is one of the these syndromes which is inherited autosomal dominant and leads to mild clinical symptoms after puberty.Objective and Hypothesis: To report a novel mutation of INSR gene mutation in a case of Type A insulin resistance who presented with transient neonatal diabetes...

Background: There is paucity of information regarding etiology and clinical profile of hypopituitarism from populations with high rates of consanguineous marriage like Sudan. We report the first data on etiological factors and clinical profiles of children with hypopituitarism from Sudan. Methodology: This study was a descriptive, hospital based, retrospective study carried out in two major pediatric endocrinology centers in Sudan (Khartoum state) from January...

Background: Vitamin D dependent rickets type II (VDDR II) is a rare autosomal recessive disorder, inherited due to mutation on vitamin D receptor (VDR) leading to end organ unresponsiveness to vitamin D. It is characterized by an early onset refractory rickets, hypocalcaemia, hypophosphatemia, growth retardation, hyperparathyroidism and elevated circulating levels of 1,25-dihydroxyvitamin D3 which is the hallmark of the disease.Objective and hypotheses: ...

Sitosterolemia is an autosomal recessive disorder affecting lipid metabolism which is characterized by decreased biliary excretion and increased absorption of plant sterols and cholesterol, leading to significantlyelevated serum levels of plant sterols. Approximately 80 homozygous or compound heterozygous variants in adenosine triphosphate-binding cassette subfamily G genes (ABCG5/ABCG8) genes have been described in patients with genetically confirmed sitosterolemia. Clinicall...

Background: Nonclassical congenital adrenal hyperplasia (NCAH), which is generally presented with symptoms of androgen excess, is inherited autosomal recessive due to different kind of mutations in the CYP21A2. Recently, high frequency of copy number variations at CYP21A2 gene and predisposition of heterozygous duplicated CYP21A2 for de novo gene aberrations has been reported.Objective and hypotheses: To evaluate clini...

Background: Main diagnosis of 46,XY disorders of sex development (DSD) with normal testosterone secretion Androgen insensivity sydrome (AIS) or 5α-reductase deficiency (5α-RD). In prepubertal period, AIS and 5α-RD present indistinguishable phenotypes that necessitate the molecular analyses for the definitive diagnosis.Objective and hypotheses: Clinical, hormonal and genetic investigation of 46,XY DSD patients who considered as PAIS or 5&#9...

Background: Neonatal severe primary hyperparathyroidism (NSHPT, MIM 23900) is a potentially lethal autosomal recessive disorder characterized by severe hypercalcemia, markedly elevated serum PTH levels and skeletal abnormalities that include multiple fractures, demineralization and erosions. It is secondary to biallelic loss of function mutation in the CASR gene that encodes the calcium sensing receptor.Case presentation: We identified a 10-day old baby ...

Introduction: Fanconi-Bickel syndrome (FBS), is a rare autosomal recessive disorder of carbohydrate metabolism (FBS, OMIM 227810), caused by defects in the facilitative glucose transporter glut-2, which transports glucose in and out of hepatocytes, pancreatic β cells and basolateral membranes of intestinal and renal epithelial cells. Characteristic features include growth failure, hepatomegaly, glucose and galactose intolerance, fasting hypoglycemia, and renal tubular nep...

Introduction: Subclinical hypothyroidism (SH) is reported up to 20% of obese population and thyroid hormone replacement in these individuals are controversial. In this study, we aimed to determine the effect of thyroid hormones on basal metabolic rate (BMR) in obesity and, thyroid hormone replacement on BMH and weight in obese patients with SH.Method: The study was conducted in 31 obese children (15 of them had subclinical hypothyroidism) admitted to our...
