Introduction: 17α-hydroxylase deficiency (17OHD) is a rare form of congenital adrenal insufficiency characterized with decreased cortisol and sex steroid biosynthesis, overproduction of ACTH, and increased mineralocorticoids. The overproduction of corticosterone hinders the symptoms of glucocorticoid deficiency and causes sodium retention, hypertension, and hypokalemia in severe cases. Affected 46,XX and 46,XY individuals are phenotypically female in the...

Introduction and Aim: In this study, we aimed to investigate the admission characteristics, the ratio of permanent/transient hypothyroidism, and the predictors of permanent or transient hypothyroidism at initial evaluation in newborns admitted in 2013 and 2014 from neonatal TSH screening program.Method and Results: During two years period, 985 babies were admitted to our clinic with screening results for evaluation, and ...

Background: Congenital hyperinsulinism (CHI) is the most common cause of hyperinsulinaemic hypoglycaemia in the neonatal, infancy, and childhood periods. Its clinical presentation, histology and underlying molecular biology are extremely heterogeneous.Objective and hypotheses: To describe the clinical characteristics, analyse the genotype–phenotype correlations and describe the treatment outcome of Turkish CHI patients.Method:...

Background: Gonadotropin independent precocious puberty (GIPP) is caused by a heterogenous group of disorders. With the exception of congenital adrenal hyperplasia (CAH), disorders causing GIPP are uncommon, and there are no studies evaluating the etiologic distribution of GIPP in a large cohort.Objective and hypotheses: To find out the relative frequencies of each etiological group in patients with non-CAH GIPP and also to evaluate the clinical and labo...

Introduction: WAGR syndrome was first described in 1964 by Miller et al. And is characterized by Wilms tumor, aniridia, genitourinary anomalies, and developmental delay. Endocrine/metabolic problems (obesity, dyslipidemia, hypertension, short stature), especially obesity, are seen in more than 70% of cases with WAGR syndrome. Here, we aimed to present a case with WAGR syndrome for endocrine evaluation.Case: A 12...

Background: Osteogenesis imperfecta (OI) is characterized by low bone mass and bone fragility mainly due to COL1A1/COL1A2 gene defects. However, >17 genes have been identified in the pathogenesis of OI. Here, we aim to characterize genotypic spectrum of our OI cohort.Methods: Forty-nine OI patients (28 males) from 38 different families (13 consanguineous/9 multiplex) were screened with the next-gene...

Background: Hypergonadotropic hypogonadism(HH) in females results from primary gonadal failure related to genetic defects affecting ovarian development and function or acquired gonadal damage; limited knowledge exist regarding underlying genes involved or potential gene X environment interactions responsible for disease trait manifestations. While pathogenic variants in single genes, chromosomal abnormalities such as Turner syndrome and acquired gonadal damage...

Introduction: Short stature is a multifactorial condition caused by both genetic and environmental factors. Genetic causes include chromosomal disorders and diseases inherited by monogenic and multifactorial inheritance. The purpose of genetic evaluation in short stature is not only for diagnosis, but also to provide additional information to the patients and their families about prognosis of the disease, treatment approaches and genetic counseling.<p clas...

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...
