International Standard Growth Charts Overestimates Stunting Prevalence in Indonesia Compared to the Indonesian National Growth Chart

Natalia Hasibuan Susi , M Djer Mulyadi , A Andarie Attika , B Pulungan Aman

Background: Growth problems, such as stunting, are commonly found in daily pediatric practice. Stunting is a significant problem in developing countries, and is part of the Sustainable Development Goals (SDG) Goal 2 of ending hunger. In Indonesia, the rate of stunting in children under 5 years old is still considered high, despite improvement in quality of life due to rapid economic development. The rate of this improvement is unequal throughout the nation, wh...

Background: Steroidogenic Factor 1 (NR5A1/SF-1) is essential for the development and function of human sex and steroid organs. Variants of SF-1 lead to a broad spectrum of phenotypes including adrenal insufficiency and differences of sex development (DSD), but data on the whole picture of phenotypes in individuals with SF-1 variants are currently lacking. We aim to investigate the phenotype of individuals with SF-1 variants in a large interna...

Background: Many organs of human body are attacked by autoimmune processes and countless number of genes are involved in their pathogenesis. Diabetes mellitus type 1 (T1DM) attaching pancreas is a common autoimmune disease in childhood. Among autoimmune thyroid diseases (AITD) we can distinguish less frequent in children population- Graves’ disease (GD). Thyroid stimulating hormone receptor (TSHR) gene encodes membrane protein responsible for thyroid metabolism. Interfero...

DNA Methylation of HSD3B2, NUR77 and RARβ Promoter Genes is Not Involved in functional Differentiation of Human Androgen-Producing Adrenocortical Cells

Burgos Maria Cecilia Alonso , Goni Javier , Saraco Nora , Garrido Natalia Perez , Rivarola Marco A. , Belgorosky Alicia , Baquedano Maria Sonia

Background: RARβ cooperates with Nur77 to in-vitro regulate HSD3B2 transcription. NUR77 expression parallels HSD3B2 expression with a much lower level in androgen-producing adrenocortical tissues (childhood virilizing adrenocortical tumours (VAT), fetal zone (FeZ) and zona reticularis, ZR). RARβ is down-regulated in starved, hyperandrogenic H295R cells. However, the mechanisms regulating this expression pattern and the relevance of RARβ to huma...

Screening of Mutations in Idiopathic Hypogonadotropic Hypogonadism Using a Targeted Next-Generation Sequencing Approach

Kolodkina Anna , Kareva Maria , Kalinchenko Natalia , Raygorodskaya Nadezhda , Malievsky Oleg , Fidelina Olga , Vasilyev Evgeny , Petrov Vasily , Naumova Maria , Tiulpakov Anatoly

Background: To date at least 30 genes are known to be associated with idiopathic hypogonadotropic hypogonadism (IHH). Analysis of all these gene candidates by Sanger sequencing would be expensive, labour-intensive and time-consuming. Recent introduction of next-generation sequencing (NGS) enables simultaneous analysis of multiple gene targets making it an attractive approach in such conditions as IHHObjective and hypotheses: To study the spectrum of mole...

Profiling of a Novel NSIAD-Causing Mutation of Vasopressin Receptor 2 and its Differential Effect on Receptor Trafficking Compared to Previously Identified Mutations

Tiulpakov Anatoly , White Carl W , Abhayawardana Rekhati , Zubkova Natalia , Seeber Ruth M , See Heng B , Pfleger Kevin D G

Background: Nephrogenic syndrome of inappropriate antidiuresis (NSIAD) results from gain-of-function mutations in the AVPR2 gene coding for vasopressin receptor 2 (V2R). In contrast, nephrogenic diabetes insipidus (NDI) is caused by loss-of-function mutations in AVPR2. Here we describe and functionally characterize a novel mutation located in the seventh transmembrane domain of V2R. This mutation was identified in a boy suffering from water-induced hyponatrem...

Disorders/differences in sex development (DSD) are defined as congenital conditions in which development of chromosomal, gonadal or anatomical sex is atypical. 46,XY DSD include defects in androgen synthesis or action or complete (CGD)/partial (PGD) gonadal dysgenesis. The aim of this study was to characterize the molecular genetic diagnosis of individuals with 46,XY DSD followed at Garrahan Pediatric Hospital.Medical records of 140 patients (P) followed...

Sex chromosome disorders, including sex chromosome mosaicism, result in a large clinical spectrum. There is scarce information about the histological pattern of these gonads.Aim: to characterize the histology and cell markers pattern in gonads of patients with chromosomal mosaicism.Gonadal biopsies from thirteen patients with chromosomal mosaicism, including chromosome Y were studied. Six were rearing as male and s...

Introduction: Autoimmune thyroid diseases are multifactorial diseases with a genetic susceptibility and environmental factors. A potential role of the Fas apoptotic inhibitory molecule 2 (FAIM2) gene, the high-affinity alpha subunit (CD25) of the interleukin-2 receptor (IL-2RA) gene, the cytotoxic T cell antigen 4 (CTLA-4) gene polymorphisms on autoimmune thyroid diseases (AITDs) in children has not been established equivocally yet.Objective: To estimate...

The contiguous gene deletion syndrome, CAH-X, was reported in an 8.5% of Congenital Adrenal Hyperplasia (CAH) patients with a TNXA/TNXB chimera. This results in deletions of CYP21A2 gene, encoding 21-hydroxylase necessary for cortisol biosynthesis, and TNXB, encoding the extracellular matrix glycoprotein tenascin-X (TNX). There are three TNXA/TNXB chimeras (CH1, CH2, CH3) that differ in the junction site, resulting in TNXB haploinsu...
