Efficiency of The Genetic Study in the Assessment of Short Stature in Pediatrics

Murillo-Vallés Marta , Ros-Peña Andrea , Valls-Llussà Aina , Herrero-Espinet Javier

Introduction: Short stature is a common disorder in children that can become a challenge for clinical and molecular diagnosis. Recent studies in genetics and the implementation of Next-Generation Sequencing (NGS) in growth disorders have demonstrated the great genetic heterogeneity of short stature and the existence of highly varied phenotypes. The absence of homogeneous clinical criteria for conducting studies makes it difficult to evaluate the efficacy of th...

Variegated Mosaic Aneuploidy Syndrome In Two Severely Undersized Siblings

Valls Aina , Ros Andrea , Murillo Marta , Garcia Belen , Martinez Daniel , Maqueda Elena , Berrocal Elena

Introduction: Variegated mosaic aneuploidy syndrome (MVA) is a rare autosomal recessive disease characterized by a variable percentage of chromosomal gains and losses, resulting in multiple mosaic aneuploidies, which explains a great phenotypic variety and may predispose to the development of cancer. Bi-allelic mutations in CEP57 are the cause of MVA2. CEP57 encodes a centrosome protein involved in microtubule stabilization and is crucial for maintaining prope...

Severe and Non Severe Forms of Autoimmune Hypothyroidism in Childhood: A Retrospective Analysis of 256 Cases

Maltoni Giulio , Vincenzi Gaia , Scozzarella Andrea , Tarantola Giulia , Cristina Vigone Maria , Cassio Alessandra

Introduction: Hashimoto’s thyroiditis (HT) is one of the most common autoimmune diseases in childhood. Despite its frequency, there are still controversies concerning the spontaneous evolution and presentation in childhood. Aim and methods: this is a retrospective study aiming to evaluate clinical and hormonal features at diagnosis and auxological parameters after 3 years in subjects with Severe Autoimmune Hypothyroidism (SAH). We defined severe hypothyr...

Hurthle Cell Carcinoma in Childhood: Retrospective Analysis of a Large Series

Pepe Giorgia , Valenzise Mariella , Zirilli Giuseppina , Cannavò Laura , Tuli Gerdi , Corrias Andrea , Wasniewska Malgorzata

Background: in general population Hurthle cell cancer (HCC) accounts for 3-7% of all differentiated thyroid cancers (TC) with a more aggressive course, while its relative prevalence and behavior in childhood is uncertain due to the lack of specific literature reviews.Objective: to describe the largest pediatric HCC cohort to date reported and to estimate its relative prevalence among TC variants in childhood.<p c...

Autoimmune Polyendocrine Sydrome Type I: A Neuroendocrine Multi-Systemic Disease with a Variable Expressivity

Carpino Andrea , Pinon Michele , Montin Davide , Tuli Gerdi , de Sanctis Luisa , Matarazzo Patrizia

Introduction: Autoimmune polyendocrine syndrome type I (APS-1) also called autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare monogenic autosomal recessive disease known by the triad of the major components hypoparathyroidism, primary adrenocortical insufficiency and chronic mucocutaneous candidosis. However, many minor diseases could be present such as other endocrine manifestations (gonadal insufficiency, DM type 1, thyroid dis...

A Deletion Encompassing Exon 2 of the ALS Gene: Analysis of a Patient with ALS Deficiency and His Family

Poggi Helena , Arancibia Monica , Benavides Felipe , Lagos Carlos , Vecchiola Andrea , Dominguez-Menendez Gonzalo , Martinez-Aguayo Alejandro

The main role of the acid-labile subunit (ALS) is to stabilize the IGFBP3/IGF complexes. Pathogenic variants in the gene coding for ALS (IGFALS) results in IGF1 and IGFBP3 deficiency, short stature, delay puberty and insulin resistance. The aim of these study was to identify the genetic cause in a patient with suspected ALS deficiency. The proband is the third son of non-consanguineous parents, evaluated for the first time at 17.3 years due to short stature (−2....

A Paternally Inherited NR5A1 Mutation in a Case of 46,XY Partial Gonadal Dysgenesis

Maciel-Guerra Andrea , Fabbri-Scallet Helena , Guerra-Junior Gil , Mello Maricilda De

Steroidogenic factor-1 (SF1), encoded by plays a central role in sex development, steroidogenesis, and reproduction in both males and females. NR5A1 mutations have been described in a diverse spectrum of disorders of sex development (DSD). We report on a case of XY Partial Gonadal Dysgenesis with paternal inheritance of a NR5A1 variant. A 17-year-old girl was referred to us due to primary amenorrhea and absence of secondary female sex characteristics. She was...

Next Generation Sequencing and Precocious Puberty: A New Diagnostic Challenge to Identify the Molecular Basis of Complex Diseases

La Barbera Andrea , Provenzano Aldesia , Artuso Rosangela , Orlandini Valerio , Giglio Sabrina , Stagi Stefano

Background: Precocious puberty is defined as the development of secondary sexual characteristics before the age of 8 years in girls and 9 years in boys. This condition results from a constant and complex interplay between predisposing genes and environmental factors. To date, the molecular analysis are all focused on reproductive-endocrine disorders such as Kallmann syndrome and hypogonadotropic hypogonadism, while the genetic bases of pubertal timing are still unclear.<p ...

Addisonian Crisis Due to Autoimmune Adrenalitis in a 14 Year Old Boy with a History of Stem cell Transplantation (HSCT)

Penger Theresa , Albrecht Andrea , Marx Michaela , Voelkl Thomas , Stachel Daniel , Metzler Markus , Doerr Helmuth G.

Background: Various endocrine complications are common after HSCT but primary adrenal insufficiency (Addison’s disease, AD) is absolutely rare. To the best of our knowledge, there is only one case of AD reported in a 9-year-old girl after HSCT and busulfan and cyclophosaphamide-based conditioning for myelodysplastic syndrome.Objective: We report on a 14-year-old boy from Albania who developed an Addisonian crisis 12.7 years after HSCT.<p class="...

The Impact of Diet on Insulin Dynamics over a 2-Year Period in Children with a Family History of Obesity

Leclerc Lucas , Gray-Donald Katherine , Benedetti Andrea , Radji Sanyath , Henderson Melanie

Background: Despite extensive evidence in adults that lifestyle modification, including a healthy diet, may prevent the onset of type 2 diabetes, studies examining the impact of chronic dietary exposures on insulin dynamics in at-risk children are lacking.Objective and hypotheses: To assess how dietary intake predicts insulin sensitivity and secretion over a 2-year period in children with a family history of obesity.Method: Data st...
