Background: Genome-wide association studies have identified more than 60 SNPs associated with BMI. Additional genetic variants, such as copy number variations (CNV), have also been implicated in the pathogenesis of obesity. Recently, the highly polymorphic CNV in the salivary amylase (AMY1) gene has been associated with obesity risk in adults.Objective and hypothesis: To assess the potential association between AMY1 copy number and BMI ...

Aims: The current study aimed that first morning voided (FMV) urinary gonadotropin measurements could be used as a noninvasive alternative to the gonadotropin-releasing hormone (GnRH) test in the assessment of the hypothalamic-pituitary-gonadal function in children.Methods: In a multi-center study, we compared FMV urinary gonadotropin concentrations with GnRH-stimulated serum gonadotropin levels in 140 girls aged 7–9 years who were evaluated for pub...

Background: Congenital hypothyroidism (CH) comprises a heterogeneous group of disorders that includes diseases of the hypothalamo-hypophyseal system. The latter are missed on TSH based screening programs leading to increased morbidity and mortality. Additional T4 determinations, allows an early detection of CH of central origin (CH-C).Objective and hypotheses: To report the findings of a neonatal screening program based on determination of TSH...

Introduction: A natiowide screening for Congenital Hypothyroidism (CH) was introduced 1996 in Russian Federation and Saratov Region. Revelation of the incidence of CH is of great value at the background of moderate iodine deficiency existing in Saratov and Saratov Region. Neonatal screening is an effective method for early detection of congenital hypothyroidism, a disorder that requires the prompt initiation of the treatment, in order to prevent the subsequent...

Background: Congenital adrenal hyperplasia (CAH) comprises a group of autosomal recessive disorders caused by defects in one of the several adrenal steroidogenic enzymes. 80–95% of CAH are due to mutations in CYP21A2 gene encoding 21 hydroxylase. Its residual activity defines the clinical form. Except deletions and large gene conversions, nine pseudogene-derived mutations are responsible for 95% of all CAH alleles. The mutational distribution varies between diffe...

Background: The transcription factor (TF) SOX2 is expressed early in the embryological development and is essential for the development of many structures like neural system, pituitary gland, eyes, ears, esophagus, and gonads. The most common clinical manifestations of mutations in the SOX2 gene are eye abnormalities (anophthalmia/microphthalmia, coloboma, nystagm, and refractive errors) and hypopituitarism (deficiency of gonadotropic, GH, TSH, and ACTH). Molecular genetic stu...

Background: Neonatal TSH screening program for congenital hypothyroidism (CH) in Central Serbia was introduced in 1983. Over the past three decades, increasing overall incidence rate of children with both permanent and transient forms of CH has been observed.Objective and hypotheses: The aim of the study was to compare incidence of CH in the first 16 years of screening (period 1) with the last 15 years of screening (period 2). We also investigated the im...

Background: 80–95% of congenital adrenal hyperplasia (CAH) cases are due to mutations in the CYP21A2 gene encoding 21 hydroxylase. The residual activity of the gene defines the clinical form. Routine mutational screening of CYP21A2 defects is shown to effectively support the complex diagnostic and treatment procedure of newborns with CAH.Objective: We aimed to characterise the phenotype of a girl with compound heterozygosity of ...

Background: In North-Eastern Italy, a newborn screening for congenital adrenal hyperlpasia (CAH) has been taking place since 2001 to diagnose the classical form of 21-hydroxylase deficiency (21-OHD). Thanks to the screening program based on 17-OHP levels in dried blood spots, early diagnosis of CAH is possible, allowing appropriate precocious treatment and reducing mortality rates. Unfortunately, a high false positive rate, especially in preterm, low-birth-wei...

Background: TSH cut-off (CO) levels has been lowered progressively in many screening programs. Nevertheless, population detected with lower CO levels differs in severity and etiology.Objective and hypotheses: To describe the etiological characteristics and severity of children detected by neonatal screening related to CO TSH levels.Method: We analysed the data of congenital hypothyroidism (CH) neonatal screening performed between J...
