CYP21A2 Gene Mutations in Congenital Adrenal Hyperplasia: Genotype−phenotype correlation in Turkish children
BACKGROUND Congenital adrenal hyperplasia (CAH) due 21-hydroxylase deficiency (21-OHD) is a common autosomal recessive disorder. It is caused by defects in the CYP21A2 gene. OBJECTIVE Our aim was to determine the frequency of common gene mutations and to evaluate genotype-phenotype correlations in Turkish 21-OHD patients. METHODS Molecular analysis of… (More)

Turner Syndrome and Associated Problems in Turkish Children: A Multicenter Study
OBJECTIVE Turner syndrome (TS) is a chromosomal disorder caused by complete or partial X chromosome monosomy that manifests various clinical features depending on the karyotype and on the genetic background of affected girls. This study aimed to systematically investigate the key clinical features of TS in relationship to karyotype in a large pediatric… (More)
Effect Of Hypo−and Euthyroid Status On Serum Cystatin C Levels
OBJECTIVE The aim of this study was to investigate the effect of hypo- and euthyroid status on serum cystatin C (CysC) levels in children and to explore whether CysC can be used as a marker of the thyroid status. METHODS Twenty five patients with hypothyroidism (10M, 15F; mean age:8.7±4.9 years) and 21 healhty age-matched controls (9M, 12F; mean age:… (More)
Clinical and Laboratory Characteristics of Children Referred for Early Puberty: Preponderance in 7-8 Years of Age
OBJECTIVE The aim of this study was to evaluate the girls referred to the pediatric outpatient clinic with a presumptive diagnosis of early puberty due to early onset of breast development or pubarche. METHODS Within the study period, we evaluated 289 subjects referred for concerns about early onset of puberty. History, anthropometric data, bone age (BA),… (More)
Z-Score Reference Values for Height in Turkish Children Aged 6 to 18 Years
OBJECTIVE Standard deviation score or Z-score reference charts are used in some countries in preference to percentile charts and are considered as better tools in assessing children with measurements outside the accepted limits of normality. Growth data for Istanbul children have previously been reported as percentiles; hence, the aim of this study is to… (More)
Is Premature Thelarche in the First Two Years of Life Transient?
OBJECTIVE Premature thelarche (PT) refers to isolated onset of thelarche in girls younger than 8 years of age. Most cases have an onset under 2 years of age. We aimed to establish whether the onset of thelarche under 2 years of age certifies a transient clinical course, as suggested by several authors. METHODS Sixty-seven girls with an onset of PT under 2… (More)
