Systemic Pseudohypoaldosteronism Type 1 Due to 3 Novel Mutations in SCNN1A and SCNN1B Genes; Report of 3 Cases

Cayir Atilla , Demirelli Yasar , Yildiz Duran , Kahveci Hasan , Yarali Oguzhan , Karaoglan Dogus Vuralli , Kurnaz Erdal , Demirbilek Huseyin

Objective: The systemic form pseudohypoaldosteronism type 1 (PHA1) is an autosomal recessive disorder characterized with defective sodium transport in many organ systems including kidney, lungs, colon, sweat glands and salivary glands. Homozygous or compound heterozygous loss-of-function mutations in the genes encoding amiloride sensitive epithelial sodium channel (ENaC) account for genetic causes of systemic PHA1.Case 1: Male patient presented with vomi...

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...

A Case of Short Stature Presenting with Multiple Exocytosis

Betul Kaygusuz Sare , Gokoglu Mustafa , Turan Serap

Objectives: Trichorinophalangeal syndrome (TRPS) is a cause of syndromic short stature; and is characterized by typical dysmorphology, ectodermal dysplasia, and skeletal findings. There are two types of TRPS; TRPS-I caused by monoallelic pathogenic variants in the TRPS1 gene, and TRPS-II caused by whole gene deletion. TRPS-II; also called Langer-Giedion Syndrome (LGS), in which multiple exocytoses can be seen in addition to typical TRPS features due t...

Juvenile Paget's Disease: Evaluation of Novel Mutation and Treatment Response

Betul Kaygusuz Sare , Gokoglu Mustafa , Turan Serap

Introduction: Juvenile Paget's Disease(JPD) is an extremely rare disease of bone characterized by progressive painful bone deformities, fractures and increased bone turnover. Findings also include deafness, loss of vision, vascular calcification and aneurysm. Here, we report two siblings presented with recurrent fractures and diagnosed as JPD by very high alkaline phosphatase levels and radiographic findings. A novel homozygous mutation in the TNFRSF11B g...

Two Novel Homozygous Mutations in WFS1 Gene in Two Turkish Families with Mild Phenotypic Expression of Wolfram Syndrome

Sherif Maha , Demirbilek Huseyin , Cayir Atilla , Ozbek Mehmet Nuri , Baran Riza Taner , Cebeci Ayse Nurcan , Tahir Sophia , Rahman Sofia , Dattani Mehul , Hussain Khalid

Background: Wolfram syndrome (WS or DIDMOAD) is a rare (prevalence of 1/770,000) autosomal recessive multi-systemic neurodegenerative disease, characterized by non-autoimmune diabetes mellitus (DM) and optic atrophy. Additional features include diabetes insipidus (DI), sensorineural deafness, urinary tract abnormalities, ataxia, psychiatric illness, and other endocrine disturbances leading to death in mid-adulthood. This syndrome is caused by recessive mutations in the wolfram...

Genotypic Sex and Severity of the Disease Determine the Time of Clinical Presentation in Steroid 17α-Hydroxylase/17,20-Lyase Deficiency

Kurnaz Erdal , Baykan Emine Kartal , Turkyılmaz Ayberk , Yaralı Oğuzhan , Yavaş Abalı Zehra , Turan Serap , Bereket Abdullah , Cayır Atilla , Guran Tulay ,

Context: Steroid 17α-hydroxylase/17,20-lyase deficiency (17OHD) is characterized by decreased sex steroids and cortisol, and excessive mineralocorticoid action. The clinical symptoms of hypocortisolemia are subtle.Aim: The clinical, biochemical, and molecular characteristics of patients with 17OHD were evaluated to determine the factors influencing the time of diagnosis and the management.Pati...

Prevalence and Causes of Short Stature and Impact of GH Therapy among Preschool Children at King Abdul-Aziz Medical City for National Guard in Riyadh, Saudi Arabia

Aboulfotouh Mostafa

Background: It is widely assumed that short stature can result in psychological, social, and physical problems. The validity and efficacy of GH in management of short stature is still debated.Aims: This study aimed to i) estimate the prevalence of short stature in preschool children (4–6 years), and determine the final diagnosis of abnormality based on different investigations, and ii) assess the impact of intervention for short stature among presch...

The Effect of Fibroblast Growth Factor 23 on Serum Phosphorus Level in Children with Diabetic Ketoacidosis

Doneray Hakan , Ozay Mustafa , Ozden Ayse , Ozturk Nurinnisa , Orbak Zerrin

Aim: The pathophysiology of developing hypophosphatemia in children with diabetic ketoacidosis (DKA) has not been sufficiently elucidated. Fibroblast Growth Factor 23 (FGF23) is a hormone that causes phosphate excretion from the kidneys. The increase of FGF23 in children with DKA may explain the pathophysiology of hypophosphatemia in these children. The aim of our study was to investigate the effect of serum FGF23 on serum phosphorus level in children with DKA...

Vitamin D Levels and Relations with Clinical and Laboratory Findings in Children with Newly Diagnosed Type 1 Diabetes

Karaguzel Gulay , Colkusu Mustafa , Bulut Ebru , Turan Ozge , Demirci Irem

Background: Vitamin D deficiency (VDD) is common in the general pediatric population of the world. Some studies reported that low vitamin D levels with an increased risk of diabetes.Objective and hypotheses: VDD can be more common in children with type 1A diabetes (DM1A) than those with type 1B diabetes (DM1B). To evaluate 25OHD levels in children with newly diagnosed DM1A and DM1B patients and investigate any relation with clinical and laboratory data a...
