Introduction: Idiopathic short stature(ISS) refers to children who are short because there is no identifiable defect in the growth hormone (GH)/insulin-like growth factor(IGF) axis and no other endocrine or genetic disorders. The genetic etiology of ISS in children was investigated in this study using targeted next-generation sequencing(NGS).Method: Eighty patients with short stature of unknown etiology were included in ...

Introduction: Childhood obesity has been associated with many physical and mental health problems.A significant relationship has been reported between psychiatric disorders, especially attention deficit hyperactivity disorder(ADHD) in obese patients due to the melanocortin 4 receptor(MC4R) gene variant, and it has been claimed that these two conditions may share common molecular pathways. However, studies on this subject are quite insufficient.<p class="ab...

Introduction: CAH is a common clinical condition with treatment and follow-up challenges. As a result, the adult height of the cases is known to be affected. We aimed to assess the growth and pubertal development of CAH patients and the factors that influence final height.Method: Between 1980-2022, 41 patients diagnosed with CAH were observed at our clinic. Only cases that attained the final height were retrospectively a...

Introduction: The SLC34A1 gene encodes the NaPi-IIa cotransporter, which plays an important role in phosphate reabsorption in the kidney proximal tubule. Inactivating mutations of this gene cause nephrolithiasis and osteoporosis, together with clinical pictures such as hypophosphatemic rickets type 1, Fanconi renotubular syndrome type 2, and infantile hypercalcemia type 2.Case: A 40-day-old male patient presented with me...

Introduction: Aggrecan, a chondroitin sulfate proteoglycan encoded by the ACAN gene, is an important structural component of the cartilage matrix. Variants in the ACAN gene are associated with a group of skeletal dysplasias called aggrecanopathy, which shows a broad phenotypic spectrum. It has been reported that some heterozygous variants in this gene are responsible for the etiology of familial or idiopathic short stature located at the lightest end of the sp...

Entrance: HOXA gene deletions cause an appearance characterized by short stature, mild developmental delay, characteristic face, small hands and feet, short and large thumbs, and urogenital malformations. Clinical signs may vary according to the content of the deletion region.Case: The case applied to our clinic with the complaint of short stature. It was learned that the patient was born at term 2500 gr and had bilatera...

Introduction: 17 β-Hydroxysteroid Dehydrogenase Type 3 (17β-HSD3) enzyme provides the conversion of ∆4-Androstenedione (A) to testosterone (T) in testicles. 17β-HSD3 deficiency is a rare autosomal recessive cause of 46,XY disorders of sexual development (DSD) and is the most common form of testosterone biosynthesis defects. The external genitalia can vary from normal female appearance to atypical genitalia.C...

Introduction: Although thyroid nodule is seen less frequently in childhood than in adults, it is more likely to be malignant. The aim of this study was to examine the characteristics of the patients followed up for thyroid nodules and to define the patients with malignant potential by laboratory, radiological and cytological evaluations.Method: 100 patients (F/M:63/37) with thyroid nodules followed up in Pediatric Endocr...

Background and Aims: Irisin is a newly discovered adipomyokine that occurs by the cleaved from a transmembrane protein called "Fibronectintype III domain containing 5" (FNDC5).Previously, there was a change in irisin levels in different prepubertal and pubertal stages.Although the mechanisms that trigger the onset of puberty cannot be explained yet, there is a hypothesis that peripheral adipose tissue and adipokines secreted there may induce the initia...

Introduction: MODY is an autosomal dominant inherited type of diabetes that has been diagnosed before the age of 25 and caused by pancreatic β-cell dysfunction. HNF1B-MODY is more rare than other MODY causes and its frequency is between 1-5%. Mutations in HNF1B (MODY 5) are associated with pancreatic agenesis, kidney anomalies, genital system malformations and liver dysfunction.Case: The patient is 8 years 2 ...
