Background: The goal of congenital hypothyroidism (CH) treatment is rapid normalization and maintenance of TSH and FT4 in the reference range. Recommended starting dose of levothyroxine (LT4) ranges from 10-15 mg/kg/d. Hyperthyroxinemia can be accepted in the context of normal TSH and LT4 should only be reduced in case of symptoms or repeatedly increased FT4. The aim of this study was to quantify duration and maximum peak of FT4 levels outside the reference range for each CH s...

Objective: The treatment of children with classical congenital adrenal hyperplasia due to 21-hydroxylase deficiency (CAH) is a challenge since both undertreatment and overtreatment with glucocorticoids can affect growth. Numerous reports in the literature have shown that the linear growth of individuals with CAH is affected and adult height is compromised. However, most of these data were obtained in the era before CAH newborn screening....

Introduction: The aim of this study was to investigate the molecular genetic etiology and to determine the relationship between genotype and phenotype with targeted next-generation sequence (NGS)analysis.Method: Patients with a clinical diagnosis of OI were included in the study. Initially, mutations in COL1A1 and COL1A2 genes which are known to be most responsible for OI were investigated. In the second step, a targeted...

Background: PAPP-A2 is a metalloproteinase that specifically cleaves IGFBPs 3 and 5. Papp-a2 knock-out (KO) mice show a reduction in body size and skeletal abnormalities.Objective and hypotheses: Our objective is to report two affected families from Spain and USA. The Spanish family presents a homozygous frameshift mutation in exon 3 of the PAPP-A2 gene (c.1927_ 1928insAT, p.D643fs25X) resulting in a premature stop codon, with 2 of 4 si...

Background: Type 2 diabetes (T2D) is an emerging disease in the pediatric population. T2D is associated with metabolic-associated fatty liver disease (MAFLD). High-density lipoproteins (HDLs) are lipoproteins that are believed to have atheroprotective properties that reduce the risk of cardiovascular disease (CVD). Current evidence suggests that the physicochemical and functional features of HDLs may play a key role in the pathogenesis of atherosclerosis.<...

Background: A few patients with NS have been reported to harbour pathogenic mutations in LZTR1 gene. RAS regulation by LZTR1-mediated ubiquitination provides an explanation for the role of LZTR1 in human disease. Mutations in this gene could hence lead to NS phenotype. Three patients with mutations in this gene and compatible NS phenotype are herein described.Case 1: A 5 year-old boy with bilateral cryp...

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...

Glutamic acid decarboxylase (GAD) is the enzyme that catalyzes the conversion of L-glutamat into GABA, one of the classical neurotransmitters with neuroinhibitory function. GAD is present in GABAergic neurons and in pancreatic beta cells. It is remarkable that Anti-GAD antibody(Anti-GADab) can have different disease manifestations, i.e., Type 1 diabetes mellitus (T1DM), Stiff-Person Syndrome, limbic encephalitis (LE), epilepsy. Cooccurence of T1DM and LE is reported in the lit...

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...

Introduction Objective: The SHOX gene is located in pseudoautosomal region of chromosomes of Xp22.33 and Yp11.32. It plays role in proliferation and differentiation of epiphyseal chondrocyte. Leri-Weill syndrome is observed with loss of an allele, while missense mutations lead to idiopathic short stature without any dysmorphic findings. This report presents clinical features of three cases diagnosed with Leri-Weill syndrome, and their responses to rhGH treatme...
