Exonic Splicing Mutations by Silent Nucleotide Variation in the Androgen Receptor Gene Causes Androgen Insensitivity Syndrome

Loch Batista Rafael , de Santi Rodrigues Andreza , Evilen da Silva Tathiana , Siqueira Cunha Flavia , Lisboa Gomes Nathalia , Rodrigues Daniela , Domenice Sorahia , Frade Costa Elaine , Bilharinho de Mendonca Berenice

Background: Androgen Insensitivity Syndrome is a common form of 46,XY DSD. In the literature, 85–90% of patients with complete form of Androgen Insensitivity (CAIS) and 30% of patients with parcial form (PAIS) have the AR gene mutation identified, In most cases are found a missense mutation with aminoacid change. Mutations without aminoacid changes (silent mutations) are rarely related to human diseases and have never been identified in patients with CAIS.<p class="ab...

Context: Children with 21-hydroxylase deficiency (21OHD) require chronic glucocorticoid administration to substitute glucocorticoids and suppress adrenocorticotropic hormone-induced hyperandrogenemia. There is still no evidence about the best timing of the highest hydrocortisone (HC) dose. Administration of the highest dose in the morning aims to mimic the physiological rhythm of cortisol, while a high dose late in the evening may inhibit the early-morning inc...

Seven-year Follow-up of Mothers from a Randomized Controlled Trial of Exercise in Pregnancy and their Offspring

Chiavaroli Valentina , Hopkins Sarah , Derraik Jose , Seneviratne Sumudu , Biggs Janene , Rodrigues Raquel , Cutfield Wayne , Hofman Paul

Background: We have previously shown in a randomised controlled trial that moderate-intensity exercise over the last 20 weeks of gestation in healthy nulliparous women led to a birth weight reduction of approximately 250 g.Objective and hypotheses: We aimed to assess the long-term effects of exercise in pregnancy on anthropometry and body composition in mothers and offspring 7 years after the intervention. We hypothesized that women who exercised in preg...

Congenital Adrenal Hyperplasia with a CYP21A2 deletion overlapping Tenascin-X gene

Rodrigues Ivo Catarina , Fitas Ana Laura , Madureira Ines , Diamantino Catarina , Gomes Susana , Goncalves Joao , Lopes Lurdes ,

Introduction: Congenital Adrenal Hyperplasia (CAH) is a group of genetic diseases characterized by impaired cortisol synthesis. 95% of CAH cases result from mutation in the CYP21A2 gene encoding 21-hydroxilase. TNX-B gene partially overlaps CYP21A2 and encodes a matrix protein called Tenascin-X (TNX). Complete tenascin deficiency causes Enlers-Danlos syndrome (EDS). A variant called CAH-X, has recently been described, resulting from CYP21...

Afebrile seizure in a toddler girl with alopecia: a case report

Crisostomo Mafalda , Simoes Joana , Canteiro Rodrigues Claudia , Galhardo Julia , Lopes Lurdes ,

Background: Calcium homeostasis is primarily regulated by vitamin D. In the absence of the active hormone or a functional receptor, bones are inadequately mineralized, leading to the development of rickets. Vitamin D-dependent rickets type 2 (VDDR2) is a rare autosomal recessive disorder caused by mutations in the vitamin D receptor (VDR) gene.Case Report: A 12-months-old girl was transported to the local hospital ED with a three-minute ...

Spanish ECOS Study Analysis: Socioeconomic Data, Adherence and Growth Outcomes with Case Studies

Rodriguez-Arnao Maria , Sanchez Amparo Rodriguez , Lopez Ignacio Diez , Fernandez Joaquin Ramirez , de la Vega Jose Bermudez , Ballano Virginia , Nieto Jenny Alvarez , Koledova Ekaterina

Background: The ECOS observational study in Spain (NCT01376921) aims to evaluate adherence to r-hGH therapy prescribed via the easypod™ electromechanical auto-injector device and to analyse factors that may influence adherence in paediatric patients. Easypod™ administers pre-set doses of Saizen® r-hGH and stores accurate records of each dose and injection taken, which can then be shared with the HCP for evaluation of the patient’s adherence.<...

A Novel Androgen Receptor Gene Mutation in Two Patients with a 46, XY Disorder of Sex Development

Fernandez Maria Sanz , Arnao Maria Dolores Rodriguez , Sanchez Amparo Rodriguez , de Leon Esther Gonzalez Ruiz , Cancio Monica Fernandez , Parera Laura Audi

Background: Androgen insensitivity syndrome in its complete form (CAIS) is a disorder of hormone resistance characterised by a female phenotype in an individual with an XY karyotype and testes producing age-appropriated normal concentrations of androgens. Pathogenesis is the result of mutations in the x-linked androgen receptor (AR) gene, which encodes for the ligand-activated AR. We report the clinical, biochemical and molecular features of two affected sisters in whom a nove...

Thyroid Nodules in Children and Adolescents

Bolado Gema Grau , de Ciriza Cordeu Maite Perez , Aguirre Andrea Cerezo , Rodriguez Javier Nunez , Sojo Amaia Vela , Estevez Amaia Rodriguez , Echevarria Itxaso Rica , Ramos Concepcion Fernandez

Background: The presence of a thyroid nodule (TN) is a rare clinical condition during childhood and adolescence. In children, classically was considered malignant and total thyroidectomy was recommended whenever a TN was detected or in the case of cold nodules. There are not long time series in children, but recent clinical guidelines recommend an initial management as in adults.Objective and hypotheses: Review TN in children in our area.<p class="ab...

Somatostin analogs in a 15 year old boy with gigantism

Hernandez Claudia , Rodriguez Saa Magdalena , Fernandez Ivana , Figurelli Silvina , Daly Adrian , Guitelman Mirta

Introduction: Pituitary gigantism is caused by a somatotroph pituitary tumor that occurs before epiphyseal closure and is associated with increased morbidity due to the systemic effects of chronic hormonal excess. It is an extremely rare disease, with an estimated incidence of 8 per million person-years. Therapeutic modalities for pituitary gigantism are the same as those for acromegaly and include surgery, medication and radiation. Medical treatment plays an ...

The Reduction in Longitudinal Growth Induced By PAPP-A2 Deficiency is Associated with Reduced Body Weight, Increased Energy Expenditure and Behavior Modification

Suarez Juan , Rivera Patricia , Vargas Antonio , Rubio Leticia , de Fonseca Fernando Rodriguez , Chowen Julie , Argente Jesus

Background: Pregnancy associated plasma protein (PAPP)-A2 is an insulin-like growth factor (IGF) binding protein (BP) protease that regulates IGF-1 availability, affecting postnatal growth. We have recently reported the first mutations in human PAPP-A2 causing short stature and changes in bone size and mineral density. However, the IGF system is involved in diverse physiological functions and to date it is unknown how mutations in PAPP-A2, which significantly reduce f...
