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: 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 ...

Laron's syndrome, or Laron-type dwarfism, is an autosomal recessive disorder characterized by an insensitivity to growth hormone.There are exceptionally low levels of insulin-like growth factor (IGF-1)caused by homozygous or compound heterozygous mutation in the growth hormone receptor gene .It causes severe short stature and can be treated with injections of recombinant IGF-1. Laron syndrome is a rare disorder. About 350 people have been diagnosed with the condition world...

Donohue syndrome (also known as leprechaunism) is an extremely rare and severe autosomal recessive genetic disorder. Leprechaunism derives its name from the fact that people with the disease often have elfin features and are smaller than usual. Leprechaunism is also characterized by abnormalities of the endocrine system ; such abnormalities include hyperinsulinemia. Due to the mutation in Insulin receptor gene, infants with leprechaunism fail to use insulin effectively (insuli...

Background: Vitamin D deficiency is prevalent in infants and children in underdeveloped countries. Secondary myelofibrosis has been reported as a complication of severe rickets and in these children anemia, myeloid metaplasia and bone aplasia strongly suggested myelofibrosis.Case report: We report a case of myelofibrosis in two years old boy with severe vitamin D deficiency rickets and hepatosplenomegaly. He presented wi...

Background: Despite a shining sun all through the year, vitamin D deficiency is still prevalent in Egyptian children which suggests a relative resistance to vitamin D in Egyptian population.Aim: To assess 25(OH)D status in healthy pre-pubertal Egyptian children and to relate its levels to anthropometric parameters in these children.Methods: Sixty healthy children aged between 3 and 10 years coming to the Outpatient clinic, Children...

Background: Gonadal dysgenesis in Turner syndrome (TS) results in pubertal delay or failure and infertility in most patients. However, up to 30% of girls with TS have spontaneous pubertal development and 2–5% have regular menstrual cycles before the onset of premature menopause. Serum anti-Mullerian (AMH) levels reflect the ovarian reserve in females, even in childhood.Objective and hypotheses: To Asses serum AMH levels in patients with TS and its r...

Background: Some studies suggested a correlation between vitamin D (VD) and the GH-IGF1 but few studies, and with controversial results, have prospectively analysed the vitamin D status in children before and after GH treatment.Objective and hypothesis: To assess VD status in pre-pubertal children with idiopathic GH deficiency (GHD); and to evaluate effect of GHD and GH treatment on VD levels.Methods: 50 pre-pubertal children with ...
