Description of a new variant in the MAMLD1 gene in an infant with microphallus and hypospadias

Riera Cristina Aguilar , Tutaya Egusquiza Dellanira Pamela , Canestrino Gennaro , Fernández Paula , Camats Núria , Clemente María , Yeste Diego

Introduction: The MAMLD1 gene is expressed in fetal and adult testes. It contributes to the development and formation of the male external genitalia in late stages of fetal organogenesis (week 8-12) and to testosterone biosynthesis. The pathogenic genetic variants of this gene determine a significant reduction in plasma testosterone concentrations, although they are not undetectable. Its most common phenotypic manifestation is hypospadias, also described in patients with micro...

Aberrant expression of agouti signaling protein (ASIP) as a new cause of monogenic severe childhood obesity

Landgraf Kathrin , Kempf Elena , Stein Robert , Hanschkow Martha , Boczki Paula , Kühnen Peter , Kiess Wieland , Blüher Matthias , Körner Antje

Here we identified and characterized a heterozygous tandem duplication at the ASIP (agouti-signaling protein) gene locus causing ubiquitous, ectopic ASIP expression in a female index patient with extreme childhood obesity. In patient-derived adipose tissue samples, we observed pronounced differentiation of stroma-vascular fraction (SVF) cells into adipocytes in the patient compared to normal control cells. We further found reduced mitochondrial maximum respir...

A comparison of the usefulness of two indices of insulin resistance: IRIHOMA (calculated from fasting glucose and insulin values) and IRIBelfiore (calculated from OGTT results) in diagnosis of metabolic complications and determining indications for possible dietary or pharmacological treatment in children

Introduction: The increasing prevalence of obesity in children and adolescents is contributing to the increasing diagnosis of insulin resistance (IR) in these individuals. However, it remains a worldwide problem to establish diagnostic criteria of IR in the developmental-age population. IRIHOMA and the IRIBelfiore are the well-known indices used in clinical practice. The aim of the study was to compare the usefulness of IRIBelfiore and IRIHOMA in the early dia...

Phenotype and genotype in patients with growth hormone difenciency and pituitary morfology abnormality

Aguilar-Riera Cristina , González-Llorens Núria , Mogas Eduard , Campos Ariadna , Fàbregas Anna , Fernández Paula , Vázquez Elida , Yeste Diego , Clemente María

Introduction: Congenital hypopituitarism is a heterogeneous disorder with isolated hormone deficiency(IPHD) or combined(CPHD). Main risk factors for CPHD include H-P abnormalities such agenesis corpus callosum(ACC), anterior pituitary hypoplasia(APH), ectopic posterior pituitary(EPP), pituitary stalk interruption(PSI), septo-optic dysplasia(SOD), and holoprosencephaly(HPE).Patients and Methods: Prospective and longitudin...

Phenolic Endocrine Disruptors as Potential Risk Factors for Early Onset Thelarche: Insights from a Population-Based Study

Sol Ventura Paula , Escribano Arantxa , Herrero Xavier , Torrebias Meritxell , Corripio Raquel , Castiello Francesca , Riaño Isolina , Olivas Alicia , Suarez Beatriz , Freire Carmen

The diagnosis of early thelarche is common in Pediatric Endocrinology consultations, with many cases lacking an organic cause. It can either spontaneously resolve, remain stable, or progress to precocious puberty. Early exposure to endocrine-disrupting environmental pollutants (EDs) with estrogenic and/or anti-androgenic effects during pregnancy or childhood may affect the timing of thelarche onset and/or puberty in girls. Further research is needed to better understand the in...

Genetic Diagnosis of Congenital Growth Hormone Deficiency by Massive Parallel Sequencing Using a Target Gene Panel

Nakaguma Marilena , de Lima Jorge Alexander Augusto , de Assis Funari Mariana Ferreira , Lerario Antonio Marcondes , de Azevedo Correa Fernanda , de Carvalho Luciani Renata Silveira , de Mendonca Berenice Bilharinho , Arnhold Ivo Jorge Prado

Background: Congenital GH deficiency (GHD) can be isolated (IGHD) or combined with other pituitary hormone deficiencies (CPHD). The identification of mutations has clinical implications for the management of patients and genetic counseling1.Objective: To prospectively conduct a molecular-genetic analysis in genes associated with IGHD or CPHD.Method: Forty patients with IGHD (n=8) or CPHD (n=32) were stu...

La puberté précoce est définie comme le développement des caractéristiques sexuelles avant l'âge de 8 ans chez les filles et de 9,5 ans chez les garçons. L'objectif de notre étude était de calculer la prévalence de la puberté précoce en consultation spécialisée et de décrire le profil clinique, paraclinique, étiologique et de prise en charge ainsi que la qua...

Polycystic Ovary Syndrome in Adolescent Girls:Towards a Treatment Focusing on Ectopic Fat

Ibáñez Lourdes , de Zegher Francis

Polycystic ovary syndrome is the most common cause of hirsutism and menstrual irregularity in adolescent girls and young women. It is often accompanied by obesity and insulin resistance and is associated to lifelong co-morbidities, including subfertility, type 2 diabetes, non-alcoholic fatty liver disease, pre-menopausal cancer, depression, low health-related Qol, and pregnancy and offspring complications. PCOS in adolescent girls is commonly driven by fat excess in subcutaneo...

Pituitary tuberculosis and hypothalamic obesity can be reversed by prolonged anti-tuberculosis treatment

Rochtus Anne , Lagae Lieven , Vermeulen Francois , de Zegher Francis

Background and methods: Sellar and suprasellar tuberculomas are extremely rare in children and most often patients present with headache, vomiting, visual disturbances, and hypofunction of the pituitary gland. Here, we report a girl with hypothalamic obesity, that recovers after antituberculosis treatment.Findings: An 11-year old girl presented with headache, fever and anorexia that progressively evolved into an encephal...
