Objective: To compare the serum 25-hydroxy Vitamin D [25(OH)D] concentrations in children and adolescents with obesity with and without hepatosteatosis, and investigate the relationship between serum 25(OH)D concentrations and severity of hepatosteatosis. We also aimed to assess the effect of vitamin D treatment after 6 months on hepatosteatosis and liver biochemistry.Methods: One hundred thirty-three obese patients with...

Polycystic ovary syndrome is the most common endocrinological disease in women of reproductive age. Although it is thought that pathologies such as insulin resistance, chronic low-level inflammation and hyperandrogenism are central theme of the disease, the exact pathophysiology of the disease has not been fully understood. This study’s aim is to reveal the relationship between routine endocrinological and immunological markers related to chronic inflammation, and to inv...

Objective: Thyroid hormone resistance is a rare autosomal dominant disease. In the pathogenesis of this disease mutations have been reported in two types of thyroid hormone receptors, called alpha and beta. Deletions or mutations in cofactors required to demonstrate receptor effect also reported in the beta receptor gene. The symptoms vary according to the cases. Here; a case of thyroid hormone resistance which is noticed by chance and not treated is presented.<p class="ab...

Context: Polycystic ovary syndrome (PCOS) is defined by androgen excess and ovarian dysfunction in the absence of a specific physiological diagnosis. The best clinical marker of androgen excess is hirsutism, while the best biochemical parameter is still a matter of debate. Current consensus guidelines recommend serum free testosterone as the most sensitive serum parameter to measure androgen excess. Recently, however, novel active androgens and androgen metabo...

The physiology of adrenarche, i.e. the development of the zona reticularis of the adrenal cortex, is mostly unknow. Some genes of steroidogenic enzymes need to be down- (HSD3B2) while others upregulated (e.g. CYB5) to enhance androgen production in zona reticularis, but it is not known how this is regulated. Micro RNAs (miRNAs) are small non-coding RNAs that can affect gene expression at posttranscriptional level. We hypothesized that miRNAs might be involved in regulating adr...

Background: Pancreas transcription factor-1 alpha (PTF1A), encoded by the PTF1A gene, is a beta helix loop(bHLH) protein which involved in the development of the pancreas and cerebellar neurogenesis. Although mutations of PTF1A cause permanent neonatal diabetes(PNDM), pancreas agenesis and cerebellar agenesis, PTF1A enhancer mutations reported causing PNDM and isolated pancreas agenesis. In the present study, we evaluate the phenotyp...

Background: Ectopic posterior pituitary gland (EPP) is characterized by an abnormal pituitary stalk and hypoplasia of the anterior hypophysis. The genetic mechanisms involved in the development of EPP remain uncertain.Objective and hypotheses: The aim of this study is to determine whether mutations in the three genes, PROP-1, LHX2, and POU1F1, are associated with the risk for and the characteristics of EPP.Method: In the Endocrinol...

Introduction: MODY; is a rare type of diabetes that occurs clinically and genetically due to a single heterogeneous gene defect. To date, 14 different genes have been identified. In order to develop a holistic genetic diagnosis approach to monogenic DM, it is aimed to investigate molecular genetic diagnosis and responsible candidate genes with targeted new generation sequence analysis and whole exome sequencing (WES) method.Metho...

Objective: The complex clinical phenotypes arising from HNF4A and HNF1A mutations are similar and include diazoxide-responsive CHI from infancy and maturity-onset diabetes of the young (MODY) from adolescence. We aimed to characterise the clinical and genetic aspects of a cohort of paediatric patients with HNF4A or HNF1A mutations.Methods: Patients from five international centres over ...

Introduction: Microarray (SNP array) method offers a powerful full genome scanning opportunity in the diagnosis of disorders of sex development (DSD).Aim and Method: We aimed to determine the copy number variations (CNVs) by using the microarray method to elucidate the molecular etiology in DSD patients. The variants found were scored according to the American College of Medical Genetics and Genomics criteria.<p clas...
