The obesity pandemic is likely multifactorial, comprised primarily of reduced caloric expenditure and increased caloric intake secondary to dietary changes, coupled with host genetic predisposition and other environmental exposures. The role of the host microbiome in metabolism, energy expenditure, and metabolic disorders, including obesity, has more recently come under scrutiny as well. For example, several perturbations in the host microbiome have been associated with obesit...

Introduction: McCune-Albright syndrome (MAS) is caused by somatic mosaic mutations in the GNAS gene. Detection of the GNAS mutations is usually difficult because of the low frequency mosaicism. Droplet digital polymerase chain reaction (ddPCR) is a new technology that enables to measure absolute quantities of target nucleic acids in a sample by counting nucleic acid molecules encapsulated in discrete water-in-oil droplet partitions.<p cla...

Background: Obesity results from interactions between environmental and genetic factors. Despite a relatively high heritability of common, non-syndromic obesity (40–70%), the search for genetic variants contributing to susceptibility has been a challenging task. To date, more than 40 genetic variants have been associated with obesity and fat distribution. However, since these variants do not fully explain the heritability of obesity, other forms of va...

Background: Hashimito's Thyroiditis is influenced by genetic and environmental factors. Interleukin-2 receptor alpha chain (IL2RA) gene polymorphism and Cytotoxic T-lymphocyte antigen 4 (CTLA 4) gene polymorphism are known to be associated with HT, but have not been established in a Caucasian children population yet. The Fas Apoptotic Inhibitory Molecule 2 (FAIM2) gene polymorphisms impact on the development of HT in children has not been reported yet....

Adrenoleukodystrophy is an X-linked, inherited metabolic disorder. Here, we present 3 clinical cases of different phenotypes with one mutation in ABCD1 gene in one family.Patient 1: At the age of 9 years, manifestation of neurological symptoms was observed, skin color changed, these symptoms progressed monthly. MRI of the brain showed 13 points on Loes scale.During the examination, the diagnosis of X-linke...

Introduction: Type 1 Diabetes (T1D) is an autoimmune disease where β-cells of the pancreatic islets are destroyed. The vast majority of T1D cases are not due to genetic predisposition, implying that the prevalence is associated with environmental, nongenetic factors. One such factor is the microbiome and its correlation with T1D has been investigated in a multitude of studies.Aims: To investigate whether the curr...

Leptin is a type I cytokine and belongs to the long-chain helical cytokine subfamily just as GH, IL-6 and G-CSF. Leptin is produced mainly in white adipose tissue and thereby reflects body energy stores. Leptin serum concentrations are high in obese and low in underweight individuals or in those with low body fat e.g. in athletes and in patients with lipodystrophy. The leptin/leptin receptor system is crucial for the regulation of body weight. Rare homozygous mutations in the ...

Backgound: There is insufficient knowledge about the characterisation of insulin, glucagon, amylin, pancreatic polypeptide (PP) and Pancreas/Duodenum Homeobox Protein 1 (PDX-1) in pancreatic tissue of children with diffuse (DCHI) and focal (FCHI) congenital hyperinsulinism (CHI).Objective(s): To understand the expression profile and localisation of insulin, glucagon, amylin, PP and PDX-1 in pancreatic tissue of children with DCHI and FCHI.<p class="a...

Introduction: Adrenoleukodystrophy (ALD) is a genetic diseases classified in the group of peroxisomal disorders caused by mutations in ABCD1, a gene located on the X chromosome. It is the most common monogenetically inherited neurodegenerative diseases. X-ALD is an inborn error of metabolism characterized by impaired peroxisomal beta-oxidation of very long-chain fatty acids (VLCFA) with a heterogeneous clinical spectrum. VLCFA accumulate principally in the CNS...

Introduction: Osteogenesis imperfecta (OI), is a genetically heterogeneous connective tissue disorder associated with skeletal fragility, deformity, and growth deficiency. Intravenous bisphosphonate therapy is the mainstay of medical treatment of this condition. Given the paucity of data from Asia we sought to evaluate the genetic epidemiology and the response to pamidronate therapy in a cohort of Malaysian patients.Method: Genetic analysis was performed...
