Background: CANDLE (chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature) syndrome is a recently described autoinflammatory disease that manifests in early infancy with recurrent fever, violaceous swelling of the eyelids, purpuric skin lesions, hypochromic anemia and elevated acute phase reactants. It is autosomal recessively inherited and associated with partial lipodystrophy, growth retardation and hepatomegaly. PSMB8 (proteasome subu...

Background: 17β-Hydroxysteroid dehydrogenase type 3 (17β-HSD3) deficiency is a rare cause of 46,XY sex reversal due to a defect in conversion of androstenedione to testosterone. It is autosomal recessively inherited and caused by mutations in 17HSD3.Objective and hypotheses: To define clinical and laboratory characteristics of 17β-HSD3 deficiency during neonatal period.Method: An 8-day-old newborn with female externa...

Aim: Osteopetrosis is caused by autosomal mutations occurring in nine genes (TNFRSF11A, TNFSF11, TCIRG1, CLCN7, OSTM1, SNX10, PLEKHM1, CA2, and LRP5). Detecting the aetiology and providing genetic counselling via individual mutation analysis of all these genes is expensive and time consuming. Whole exome sequencing is currently increasingly used given that the cost and the time needed are similar to that of single gene sequencing analysis. Here, two newborns,...

Background: Although it has been recommended to start treatment in the range of 22-35 µg/kg/day in growth hormone (GH) deficiency, individualized dose selection is more preferred for those patients instead of a fixed dose. However, there is no consensus as to which dose should be started for which patient. In this study, we aimed to reveal the factors that affect the clinicians' preferences in the selection of the starting dose of GH treatment.<...

Introduction: Subclinical left ventricular (LV) dysfunction may occur in chronic diseases such as type 1 diabetes mellitus (T1DM). For the patients at the early asymptomatic stage, LV reserve function is a sensitive index to detect subtle LV dysfunction. The purpose of our study is to assess the LV reserve function using treadmill exercise stress echocardiography (ESE) in children with T1DM.Method: The study was planned ...

Background: Leptin receptor (LEPR) deficiency is a rare genetic disorder that causes severe early-onset obesity. Most children with this condition are obese before the age of one. Leptin and LEPRs are needed for the regulation of appetite and body weight. The most common symptom, present in 96% of patients, is impaired appetite regulation, also known as hyperphagia. Other clinical features include pituitary hormone disorders; such as hypogonadotropic hypogonad...

Introduction: Congenital adrenal hypoplasia, a rare cause of childhood primer adrenal insufficiency, is caused by defects in transcription factors involved in the development of adrenal gland. One of them is the NROB1 (DAX1) gene, localized in Xp21.2. DAX1 mutations have been identified that cause X-linked adrenal hypoplasia congenita. Infants affected with X-linked adrenal hypoplasia congenita may present with salt-wasting, micropenis or cry...

Background: Melanocortin-4 receptor (MC4R) mutations are the most common known cause of monogenic obesity but there is no data for Turkish children.Objective: To determine the prevalence of MC4R mutations in a group of Turkish morbid obese children and adolescents.Method: MC4R gene was sequenced in 47 consecutive morbidly obese children and adolescents (28 girls and 19 boys, aged 1–18 years) who presented dur...

Background: Type 1 diabetes mellitus is characterized by presence of several organ specific autoantibodies. Anti-cyclic citrullinated peptide (anti-CCP) antibody is a promising marker of rheumatoid arthritis (RA) which is known to coincide with autoimmune diabetes. Presence of these antibodies was not investigated in children with type 1 diabetes.Objective and hypotheses: To evaluate presence of anti-CCP antibodies in children with type 1 diabetes compar...

Aim: Acrodysostosis is a rare genetic syndrome characterized by small hands and feet with short, stubby fingers and toes, cone shaped epiphyses, broad nasal root, various abnormalities of mandible, skull, and vertebra, short stature, and mental retardation. Because of the hormone resistance that would accompany, acrodysostosis can be confused with pseudohypoparathyroidism. Mutations of PRKAR1A and PDE4D are reported to be responsible for the disease in less t...
