Introduction: X-linked adrenoleukodystrophy (X-ALD) is an inherited peroxisomal disease characterized by beta oxidation disorder that causes the accumulation of very long chain fatty acids (VLCFA) in all tissues. It presents with clinical signs due to accumulation of VLCFA in brain white matter, testes, adrenal cortex and skin fibroblasts. Here, we will present a case applied to the outpatient clinic due to not going through puberty period and who was diagnose...

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...

Introduction: Treatment adherence is crucial for the success of Growth Hormone (GH) therapy. Non-adherence rates have varied over a wide range from 5% to 80% in the literature. Several factors may have an impact on treatment adherence. Besides, with the COVID-19 pandemic that affected the whole world, there were problems with the hospital admission and routine controls of the patients who used GH treatment.Objective: The...

Introduction: Silver-Russell syndrome (SRS) is a rare, well-defined genetic disease characterized by intrauterine and postnatal growth retardation, short stature, triangular face, relative macrocephaly and body asymmetry. The most common molecular pathologies are loss of methylation (50%) of the imprinting center in the p15.5 region of the paternal 11th chromosome and maternal uniparental disomy of the 7th chromosome (5-10%). The IGF2 (insulin-like growth fact...

Introduction: Interstitial deletions on the long arm of the 12th chromosome are rare and often occur de novo. These deletions have been found to be associated with mental retardation, developmental delay, growth retardation and various congenital anomalies in different studies. In studies up to date, it has been determined all interstitial 12q deletions are clustered between five regions on this chromosome (HMGA2, GRIP1, LEMD3, MSRB3, and TMBIM4). Low birth we...

Introduction: Primrose syndrome was defined in 1982. It is characterized by characteristic facial appearance, macrocephaly, global developmental delay, intellectualdisability and calcification in the outer ear. It occurs with loss-of-function mutations in the ZBTB20-gene. This gene is a transcriptional gene suppressor regulator and is effective on neurogenesis, glucose homeostasis, and postnatal growth. Here, a case with Primrose syndrome will be presented.</p...

Introduction: Differential diagnosis should include congenital adrenal hyperplasia (CAH) in premature adrenarche patients. Clinically, it is possible to diagnose late onset and simple virilisation CAH caused by 21 hydroxylase deficiency because the criteria are better defined and genetic tests are widely available. But especially late onset 11 Beta hydroxylase deficiency can be very difficult to diagnose because the diagbostic criteria are not well defined and...

Background: Short stature homeobox-containing (SHOX) gene that strongly affects height. Due to high prevalence of SHOX gene mutations, in all children with unexplained short stature should be investigated to benefit from early growth hormone (GH) treatment. The aim of this clinical study was to determine the rate of SHOX haploinsufficiency in short stature patients and describe their anthropometric measurements.Methods: Between...

Introduction: Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder. Diagnosis, monitoring of treatment, adjustment of drug doses are important for height, puberty and psychologic status of patients and their families.Materials & Methods: Patients with classical CAH due to 21-hydroxylase deficiency who were followed regularly in pediatric endocrinology clinic between 1994 and 2019 were included in this study. Inform...

Introduction: Steroid hormone biosynthesis is initiated by the cholesterol side-chain cleavage enzyme (P450scc), which converts cholesterol to pregnenolone, the precursor of all steroid hormones. This enzyme is encoded by the CYP11A1 gene and is responsible for glucocorticoid, mineralocorticoid and sex steroid synthesis in the adrenal glands, gonads and placenta. Early or late onset adrenal insufficiency, 46, XY sex development disorder, and hypergonadotropic ...
