Background: The aetiology of congenital hypopituitarism (CH) is unknown in the majority of patients. In our cohort of 200 cases, it was possible to establish the genetic cause in only 13 patients (6.5%). Copy number variants (CNVs) have been implicated as the cause of genetic syndromes with previously unknown aetiology.Objective: To study the presence of CNVs and its relevance in patients with CH of unknown cause associated with complex phenotypes.<p...

Nephrogenic Diabetes Insipidus with Partial Response to Ddavp Caused by a Novel AVPR2 Splice Site Mutation

Schernthaner-Reiter Marie Helene , Adams David , Nilsson Ola , Trivellin Giampaolo , Ramnitz Mary Scott , Raygada Margarita , Golas Gretchen , Faucz Fabio R. , Dileepan Kavitha , Lodish Maya B. , Lee Paul R. , Markello Thomas C. , Tifft Cynthia J. , Gahl William A. , Stratakis Constantine A.

Background: Congenital diabetes insipidus (DI) can be due to mutations in the arginine vasopressin (AVP) gene (familial neurohypophyseal DI), the AVP receptor type 2 (AVPR2) or aquaporin 2 (AQP2) genes (congenital nephrogenic DI, NDI). The clinical manifestation of congenital NDI, especially the response to AVP, can vary greatly depending on the functional effect of the AVPR2 mutation. Here we present two male siblings with NDI and partial response to ddAVP.<p class="abste...

Genetic Causes of Disproportional Short Stature Identified by Whole Exome Sequencing

Funari Mariana F A , Vasques Gabriela A , Lerario Antonio M , Freire Bruna L , Nishi Mirian Y , Franca Monica M , Shinjo Sueli M O , Marie Suely K N , Arnhold Ivo J P , Jorge Alexander A L

Background: Disproportional short stature (DSS) is the most frequent clinical presentation of skeletal dysplasias, which are a heterogeneous group of more than 450 disorders of bone. Skeletal survey is important to establish the diagnosis and to guide the genetic test, but has several limitations, especially in mild and atypical cases.Objective and hypotheses: To identify the genetic aetiology of DSS by exome sequencing.Method: Who...

Background: FOP is an ultra-rare, severely disabling genetic disorder characterised by progressive heterotopic ossification (HO) following flare-ups. The median age at diagnosis is 5 years, and patients are managed by multiple specialties. No study to date has provided a longitudinal evaluation of FOP. Final data are presented for participants, aged <25 years, enrolled in the first 36-month, prospective, global natural history study of FOP (NCT02322255).</...

Efficacy and Safety of Corifollitropin Alfa in Combination with Human Chorionic Gonadotropin for Initiation or Restoration of Puberty in Adolescent Males Aged 14 to < 18 Years with Hypogonadotropic Hypogonadism

Shankar R. Ravi , Shah Suneri , Joeng Hee-Koung , Mendizabal Geraldine , Guan Yanfen , Stegmann Barbara J. , Nieschlag Eberhard , Behre Hermann M. , Swerdloff Ronald S. , Fox Michelle C. , Kaufman Keith D. ,

Background: Combinations of follicle-stimulating hormone (FSH) and human chorionic gonadotropin (hCG) have been successful in treating males with hypogonadotropic hypogonadism (HH). The aim of this study was to investigate the efficacy and safety of corifollitropin alfa (CFA), a long-acting FSH analog, combined with hCG to induce testicular growth and pubertal development in adolescent males with HH.Methods: This was a 6...

Lonapegsomatropin (TransCon hGH) is an investigational once-weekly prodrug of somatropin for the treatment of GHD. Previous trials in treatment-naïve (52-week heiGHt Trial) and treatment-experienced children (26-week fliGHt Trial) have reported the efficacy and safety of lonapegsomatropin. Subjects were eligible to enter the open-label extension enliGHten Trial, which continues to evaluate weekly lonapegsomatropin in pediatric GHD. In heiGHt, treatment-naïve subjects...

Background: Primary ovarian insufficiency (POI) affects 1% of women and is associated with significant medical consequences. In approximately 10% of cases, POI presents early with absent puberty or primary amenorrhoea. A genetic cause for POI can be found in up to 30% of women. Identified genes often relate to the complex biological processes occurring in fetal life which underpin normal ovary development and function in later adulthood.Objective: We aim...

Introduction: In rare cases of obesity, genetic defects lead to hyperphagia and severe early-onset obesity. Genetic testing in patients with a suspected genetic obesity phenotype is important, as it can lead to patient-tailored treatment advice. For children, the Endocrine Society (ES) recommends genetic testing in children with early-onset of obesity (<5 years) and hyperphagia. It is unclear whether these recommendations can also be used in adult obesity c...
