Background: Raine Syndrome (RS) is characterized by hypophosphatemia and typical facial dysmorphic features. Subperiostal thickening and diffuse generalized osteosclerosis are the most common radiological findings. Biallelic loss of function mutations in FAM20Cgene cause RS and by reduction of the transcription of DMP1 leads to FGF23-related hypophosphatemia. Here we present a new case with RS.Case: A 9-month-ol...

Objective: Fetuin-A has many different functions due to its ability to bind to different toll-like receptors in different tissues. Working in different groups will contribute to our understanding of the pathophysiology of Fetuin-A. In this study, we aimed to evaluate Fetuin-A levels in obese adolescents and the relationship between Fetuin-A and anthropometric data, insulin levels and high sensitivity CRP(HSCRP). Material and Meth...

Objectives: Forkhead box A2 (Foxa2) is a transcription factor that plays a key role in foregut, pancreatic and central nervous system development. Here, we describe a 7 years old boy whose phenotype is consistent with FOXA2 defect.Case: A 3 months old boy was referred for recurrent hypoglycemic events. He was born to unrelated parents at term with a birth weight of 3690 gr. At 6 hours of life he had severe hypoglycemia (...

Introduction: Policystic ovarian syndrome (PCOS); is an endocrinopathy characterised by overlap of hyperandrogenism and hyperinsulinism and chronic anovulation. Etiopathogenesis is still not clearly defined. Fetuin-A is aserum glycoprotein. It is shown to play regulatory functions in many inflammatory processes. We aim to define the relationship of fetuin-A levels with hyperandrogenism and hyperinsulinism in PCOS patients and study the role in pathophysiology....

Introduction: Turner Syndrome (TS) is known to be associated with a high risk of cardiac anomalies and cardiovascular diseases. Detailed cardiac evaluation at diagnosis and serial evaluation for dissection is warranted.Aim: This study aimed to evaluate TS patients for cardiac pathology using MRI.Methods: Clinical findings, karyotypes, echocardiogram results, cardiac MRI findings of 33 patients with TS were evaluated. Measurements o...

Background: Congenital lactase deficiency (CLD) occurs as a result of loss of function of intestinal lactase-phlorizin hydrolase (LPH) encoded by LCT gene. Patients usually present with osmotic diarrhea in the first few days of life. Although the exact mechanism is not known, hypercalcemia is a common feature of CLD; with calcium levels up to 14 mg/dl and nephrocalcinosis have been reported. However, CLD is frequently overlooked in the differential diagnosis o...

Keywords: children, primary osteoporosis, next-generation sequencingBackground: Primary osteoporosis (POP) is a rare bone fragility disorder of childhood and is mainly related to osteogenesis imperfecta (OI). However, patients without clinical OI features with recurrent long bone and/or vertebral fractures who comply with the osteoporosis criteria are considered to have non-OI POP. Diagnosis and classification of non-OI ...

Background: Primary adrenal insufficiency (PAI) is a potentially life-threatening condition that requires accurate diagnosis and urgent treatment. Congenital adrenal hyperplasia is the most common cause of PAI in children. Non-CAH causes of PAI are relatively rare. Although several molecular causes have been found, it is emerging that considerable overlap in the clinical and biochemical features of these conditions exists.Objective and hypotheses: We inv...
