Background and hypothesis: Mitochondrial disorders are multisystemic conditions associated with sensorineural hearing loss, encephalomyopathy, lactic acidosis, and non-autoimmune diabetes. The majority of molecular etiologies involve mutations in the genes encoding the oxidative phosphorylation system's components. Superoxide generation is significantly increased and causes oxidative damage in the affected tissues in these disorders. The establishment of ...

Background: In adult studies, serum uric acid level (SUA) has been shown to be associated with cardiometabolic anomalies of metabolic syndrome such as insulin resistance, hypertension, increased carotid intima thickness, and hyperuricemia is considered as an independent risk factor for atherosclerosis and cardiovascular disease. Early cardiovascular changes in obese children and studies on the relationship between metabolic syndrome and hyperuricemia are quite...

Background: Maturity-Onset Diabetes of the Young (MODY) is a rare monogenic form of diabetes that result in β-cell dysfunction. MODY accounts for 2–5% of all diabetes cases. We presented here a family with MODY2 caused by a novel heterozygous p.L164I (c.490 C>A) mutation of the GCK gene.Case: A 15,5-year-old girl was admitted to our department because of fasting hyperglycemia. She had no polyuria, polydipsia and weight loss...

Background: Macro TSH is a high molecule weighed complex with low bioactivity that is comprised of TSH and anti-TSH antibodies. Potentiality of macro TSH should be kept in mind in clinically euthyroid and asymptomatic patients with normal free T4 and T3 levels and relatively high TSH levels. Diagnosis of macro TSH is suspected if polyethylene glycol (PEG) precipitable TSH exceeds %75 and confirmed if high molecule weighed TSH is shown with gel filtration ...

Introduction: Maturity-onset diabetes of the youth (MODY), is a genetically and clinically heterogeneous group of diseases in the pancreatic β–cell that impair insulin secreation. It mostly caused by heterozygous mutations in one of 11 different genes associated with β–cell function. The aim of this study is detection of the distribution of both known and novel point mutations of these genes in Turkish population.Pati...

Background: Deficiency of 11β-hydroxylase is the second most frequent type of congenital adrenal hyperplasia and more common in Turkey than other populations.Objective and hypotheses: The purpose of this study is to examine the spectrum of CYP11B1 gene mutations in Turkish population.Method: 17 patients from 13 families are included in this study. Diagnosis was based on virilisation and high levels of 11-deoxycortisol. 15 case...

Purpose: MODY is a monogenic diabetes with autosomal dominant inheritance that usually occurs in adolescence or young adulthood. It constitutes 1% of diabetes cases in childhood. The diagnosis of MODY is very difficult due to genetic heterogeneity, rarity, and clinical overlap with other diabetes types. In recent years, the diagnosis of MODY has become easier with genetic developments. On the other hand, misinterpretation of results can cause confusion. In thi...

Introduction: Rabson-Mendenhall Syndrome (RMS) is an autosomal recessive, extremely rare, serious insulin resistance syndrome that occurs as a result of mutation in the insulin receptor (INSR) gene. Pathogenic variants in the INSR gene cause a broad spectrum of inherited insulin resistance syndromes. Here, a male case who presented with the complaint of diffuse acanthosis nigricans and was diagnosed with RMS is shared. Case Repor...

Objectives: Type 1 diabetes mellitus (DM) is an autoimmune disease caused by the destruction of pancreatic beta cells. The frequency of Type 1 DM is increasing, and the highest incidence rate is in children under 5 years of age. It is estimated that children under the age of five will develop approximately 70% of the cases under the age of 15, with an increased incidence.In our study, we aimed to evaluate the demographic, clinical an...

Introduction:Premature adrenarche (PA) is the most common cause of premature pubic and axillary hair growth before the age of 8 in girls. At the time of diagnosis, the height and bone age of the cases with premature adrenarche were determined to be higher than their peers. The long-term effects of advanced bone age on the final length of the cases are controversial. In this study, it is aimed to share the long-term follow-up data of the cases diagnosed with pr...
