A Novel GLUT1 Mutation in a Patient with Apparently Normal Cerebrospinal Fluid Glucose Level

Ustyol Ala , Duman Mehmet Ali , Hatipoglu Halil Ugur , Elevli Murat , Duru Hatice Nilgun Selcuk

Background: Glucose is the main energy source for the brain’s cells. Glucose transporter 1 (GLUT1), encoded by the SLC2A1 gene, is a membrane protein that plays an essential role in the transport of glucose across the blood-brain barrier. A mutation in GLUT1, so-called GLUT1 deficiency syndrome (GLUT1 DS; OMIM #606777), results in low levels of glucose in the cerebrospinal fluid despite normoglycaemia. GLUT1 deficiency causes a series of symptoms that ma...

Is Type 1 Diabetes Mellitus Predictable? Investigation of Predictive Markers n Siblings of Probands with Newly Diagnosed Type 1 Diabetes Mellitus

Albayrak Serpil , Karaoglan Murat , Yıldırım Ahmet , Keskin Mehmet ,

Background/Aim: Type 1 diabetes Mellitus (T1DM) often presents with clear clinical signs after a long-term asymptomatic autoimmune process. This long and silent period has been leading to an increase in awareness day by day in order to prevent and predict the development of the disease. Among the well-known genetic and environmental risk factors, close relatives of the index cases constitute a population that is quite suitable for predicting and preventing the...

Evaluation of The Relationship Between the Immune and Endocrine System in Children Diagnosed with Polycystic Ovary Syndrome

Uygur Balık Ahmet , Keskin Mehmet , Karaoglan Murat , Keskin Ozlem , Yıldırım Ahmet , Albayrak Serpil

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...

A Very Rare Thyroid Hormone Resistance Case Having Heterozygous Mutation in THRB Genes

Keskin Mehmet , Yılmaz Seniha Kiremitci , Kaplan Emel Hatun Aytac , Karaoğlan Murat , Karaer Kadri , Keskin Ozlem

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...

Clinical characteristics of patients presented with primary adrenal insufficiency due to a p.R451W mutation in the CYP11A1 gene

Çayır Atilla , Demirbilek Huseyin , Nuri Ozbek Mehmet , Kurt lknur , Karaoglan Murat , Albayrak Serpil , Nuri Dundar Bumin , Guran Tulay

Background and objective: The first and rate-limiting step of steroidogenesis is the conversion of cholesterol to pregnanolone which is catalyzed by the P450scc side chain cleavage enzyme (encoded by CYP11A1 gene-SCC). Homozygous recessive mutations of the CYP11A1 gene cause a global steroid hormone deficiency thereby disorders of sexual development in 46, XY individuals with a variable phenotype depending on the mutation characteristics. About 60 cases of SCC...

The serum steroid signature of PCOS hints at the involvement of novel pathways for excess androgen biosynthesis

Murat Altinkilic Emre , du Toit Therina , Sakin Onder , Attar Rukset , Grössl Michael , E. Flück Christa

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...
