Endocrine Disruptors and Polycystic Ovary Syndrome: Phthalates

Akin Leyla , Kendirci Mustafa , Narin Figen , Kurtoglu Selim , Kondolot Meda , Saraymen Recep , Kocak Selda Ozkan , Hatipoglu Nihal , Elmali Ferhan

Background: Polycystic ovary syndrome (PCOS), characterized by hyperandrojenemia, anovulatory periods and polycystic ovaries, is a disorder in which metabolic and reproductive abnormalities overlap. The etiopathogenesis is currently unclarified. Besides the evidence of genetic causes, environmental factors are considered to be involved in development of phenotype. Phthalates are widely used industrial chemicals and have several known untoward effects on human reproductive heal...

Evaluation of Growth Pattern in Prader-Willi Syndrome

Gunes Sevinc Odabasi , Ergur Ayca Torel , Katircioglu Mehmet , Bulbul F. Selda

Background: The main reason of decrement of growth in children with Prader-Willi Syndrome (PWS) is dysfunction of hypothalamo-hypophseal axis (HHA) and a decrease in the capacity of secretion of growth hormone (GH). In fact, in some cases, GH levels are normal, so there may be other factors in the etiology.Objective and hypotheses: In this study, 19 months old PWS case with growth failure is represented.Method: 13 months old male p...

Nalbantoglu Ozlem , Ozkan Behzat , Tunc Selma , Apa Hursit

Background: Although the highest prevelance rates of childhood obesity and overweihgt have been observed in developed countries, its prevelance is reported to be increasing in developing countries as well. Prevelance of obesity and overweight in different regions of Turkey ranges between 1.6–7.8 and 9.9–17.6 respectively.Objective and hypotheses: The purpose of this study was to investigate the prevelance of obesity and overweight among student...

A Rare Case of Skeletal Dysplasia: Homozygous Mutation in ACAN Gene

Arslan Gulcin , Hazan Filiz , Kirkgoz Tarik , Ozkan Behzat

Spondylo-epimetaphyseal dysplasia -ACAN (SEMD- ACAN) is a rare form of osteo-chondrodysplasia that represents a group of vertebral, epiphyseal, and metaphyseal dysplasia. This genetic condition is caused by biallelic loss-of-function mutations in the ACAN gene, which encodes for aggrecan, an essential component of the extracellular matrix in cartilage. Biallelic loss-of-function mutations in this gene result in a range of characteristic symptoms, including disproportionate sho...

Early Onset Monogenic Obesity: Two Cases with Homozygous Mutation in Lepr Gene

Nalbantoglu Ozlem , Acar Sezer , Koprulu Ozge , Arslan Gulcin , Ozkaya Beyhan , Hazan Filiz , Gursoy Semra , Ozkan Behzat

Introduction: Although the majority of the cases with obesity have a multifactorial etiology, rare monogenic forms of obesity exist. Several genetic disorders have been described that lead to early onset monogenic obesity. Leptin (LEP), leptin receptor (LEPR), melanocortin 4 receptor (MC4R), proprotein converting protein subtilisin / kexin-type 1 (PCSK1) and proopiomelanocortin (POMC) are the genetic mutations that have been most frequently shown to cause mono...

Autoimmunepolyendocrinopathy-Candidiasis-Ectodermal Dystrophy: A Case Report

Celik Tanju , Nalbantoglu Ozlem , Gursoy Semra , Sangun Ozlem , Arslan Gulcin , Ozkan Behzat

Introduction: Autoimmune polyendocrinopathy, candidiasis and ectodermal dystrophy (APECED) is a rare hereditary disorder with autoimmun manifestations affecting both endocrine and non-endocrine tissues. It is caused by mutations in the autoimmune regulatory (AIRE) gene which is defined by the presence of two of the three major components: Chronic mucocutaneous candidiasis, autoimmune hypoparathyroidism and Addison’s disease. Clinical manifestations may be developed during...

A Novel Inactivating Compound Heterozygous Mutation in KISS1R/GPR54: Cases of Three Siblings

Nalbantoglu Ozlem , Arslan Gulcin , Koprulu Ozge , Hazan Fılız , Gursoy Semra , Ozkan Behzat

Introduction: Kisspeptin is a neuropeptide, encoded by the KISS1 gene, which acts upstream of gonadotropin-releasing hormone (GnRH) neurons and also has a critical role for maturation and function of the reproductive axis. Inactivating mutations of its receptor (KISS1R) cause normosmic isolated hypogonadotropic hypogonadism (IHH). In this report, we aim to present three siblings who have IHH due to novel compound heterozygous KISS1R mutation.Cas...
