Background: Butyrate is a short-chain fatty acid closely related to the ketone body β-hydroxybutyrate (BHB) considered as the major source of energy during prolonged exercise. During fasting, when the liver switches to fatty acid oxidation, a rise in serum GH occurs concomitantly with the accumulation of BHB and short chain fatty acids (SCFA) acetate, propionate and butyrate. Interactions between GH, ketone body and SCFA during the metabolic adaptation to fasting are poor...

Background: Adrenoleukodystrophy (ALD) is a genetic disease associated with demyelination of the CNS, adrenal insufficiency, and accumulation of very long-chain fatty acids in tissue and body fluids.Objective: To research the clinical features, laboratory tests, imaging examinations and treatment on children who suffer from X-linked ALD. Also aim at revealing the correlation between the severity of disease and level of very long chain fatty acids (VLCFAs...

Introduction: Adrenoleukodystrophy (ALD) is a rare X- linked disease caused by a mutation of the peroxisomal ABCD1gene. It is a progressive condition with a variable clinical spectrum that includes primary adrenal insufficiency, axonal demyelination and the accumulation of high levels of very long chain fatty acids (VLCFA) in the plasma and tissues.Methods: It’s a retrospective study of all cases of X-linked ALD who...

Introduction: Congenital lipoid adrenal hyperplasia (lipoid CAH), is a rare subtypes of adrenal hyperplasia yet the most fatal form, which seriously disrupts adrenal and gonadal steroidogenesis by a defect in the conversion of cholesterol to pregnenolone. Affected patients show salt loss from impaired mineralocorticoid and glucocorticoid synthesis. The defect in lipoid CAH is mainly in the steroidogenic acute regulatory protein (StAR), which promotes entry of ...

Mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) is a mitochondrial multisystem disorder. The m.3243A>G pathogenic variant in the mitochondrial gene MT-TL1 is present in approximately 80% of individuals with MELAS. In this article, we report a 7-year-old girl with the classical MELAS phenotype. After the age of 1 year, she had recurrent episodes of nausea and vomiting. In this episode, she presented with focal seizures ...

Background: Fibrochondrogenesis 1 (FBCG1) is known as an autosomal recessive syndrome, which is related to short-limbed skeletal dysplasia. The disease is clinically characterized by a flat midface with a small nose and anteverted nares, significant shortening of all limb segments but relatively normal hands and feet, and a small bell-shaped thorax with a protuberant abdomen. Mutations in the gene encoding the α1 chain of type XI collagen (COL11A1) are s...

Introduction: Plasma triglyceride (TG) is formed by an exogenous pathway taken from food and by an endogenous pathway produced from the liver. Primer hypertriglyceridemia occurs by genetic reasons. Higher TG levels occurs in lipoprotein lipase (LPL), ApoC2, ApoA5 gene defects. Secondary hypertriglyceridemia is caused by obesity, insulin resistance, alcohol and some drugs. In that study, we evaluated 10 patients with primer hypertriglyceridemia regards to clini...

Background: Somapacitan is a reversible albumin-binding growth hormone (GH) derivative developed for once-weekly administration in patients with GH deficiency (GHD). It consists of a human GH backbone, similar to endogenous human GH, with one amino acid substitution, attached to an albumin binder via a linker chain.Objective: Absorption, metabolism and excretion (AME) of somapacitan were investigated in a Phase 1 trial (...

Background: Hypospadias is a common characteristic of Disorders of Sex Development (DSD). At the present time a molecular diagnosis is not reached in over 50% of cases. The DDD Study represents a useful resource of large molecular and phenotypic datasets obtained from individuals with an undiagnosed developmental abnormality including DSD.Objective: To review associated features and identify likely pathogenic variants in previously undiagnosed DDD partic...

Introduction: Zinc α2-glycoprotein (ZAG) is a single-chain polypeptide with molecular weight of 40-kDa, and is secreted from various tissues. It plays several imperative functions in the human body, such as lipid mobilization and immunoregulation. ZAG enhances lipolysis and is involved in reduction of fatty acids in adipose tissues. ZAG has High sequence similarity to MHC-I molecules and is suggested to be a truncated secretory MHC-I–like protein. ...
