Background: Children with familial forms of central diabetes insipidus (CDI) display polyuria and polydipsia within the first years of life.Objective and hypotheses: We hypothesize that children with an early-onset idiopathic CDI might be affected by de novo genetic mutations.Method: Eleven children aged between 1 month and 7 years with polyuria and polydipsia and negative family history were enrolled. In nine of them with...

A Rare Cause of Proteinuria Presenting with Short Stature, Cataract, and Dysmorphic Findings: Lowe Syndrome with A Novel de Novo Mutation in the OCRL1 Gene

Gürbüz Fatih , Bilginer Gürbüz Berrak , Özalp Yüreğir Özge , Çayır Atilla

Oculocerebrorenal syndrome of Lowe (OCRL) is an X-linked and multisystem disorder with clinical symptoms of congenital cataracts, severe mental retardation, hypotonia, areflexia, and incomplete Fanconi syndrome of the proximal renal tubules. We report a 15-year-old short stature male with a severe form of OCRL syndrome, diagnosed based on bilateral congenital cataract, proteinuria, tubulopathy, and dysmorphic findings. The physical examination revealed a height of 152 cm (-2.7...

A novel de novo SAMD9 gene variant causing MIRAGE syndrome associated with steroid-resistant nephrotic syndrome in a 46,XY male.

Farakla Ioanna , Sertedaki Amalia , Barbara Tatsi Elizabeth , Sandu Adina , Kanaka-Gantenbein Christina

Introduction: MIRAGE syndrome (Myelodysplasia, Infections, Restriction of growth, Adrenal hypoplasia, Genital phenotypes, Enteropathy, OMIM# 617053), is a congenital disorder caused by heterozygous gain of function mutations in the growth repressor gene SAMD9, inherited autosomal dominantly, although de novo variants are often reported. The syndrome was first described in 2016 and to date various cases have been reported, presenting a wide sp...

Introduction: Non-communicable diseases are recognized as a major cause of morbidity in low and middle-income countries (LMICs). There are 21 francophone countries (>100 million speak French) in Sub-Saharan Africa (FSSA). We identified only 19 pediatric endocrinologists in FSSA (37% in Cameroon and Senegal) mostly trained in France or through the successful anglophone “Paediatric Endocrine Training Centers for (West) Africa” (PETC[W]A) offered i...

A de novo novel heterozygous deletion mutation in steroidogenic factor 1 gene (NR5A1) in a 46,XY female with sex reversal, primary adrenal insufficiency and splenic aplasia: A 13 years follow-up

Wang Danyi , Ma Huamei , Zhang Jun , Du Minlian , Li Yanhong , Chen Qiuli

Background: Steroidogenic factor-1 (SF1) is a nuclear receptor transcription factor that plays a crucial role in regulating the adrenal, gonadal, splenic development, steroidogenesis and reproduction.Objective: To describe a Chinese 46,XY female with sex reversal, primary adrenal insufficiency and congenital splenic dysplasia harboring a novel de novo heterozygous deletion in NR5A1 gene.<p class="ab...

The clinical burden and healthcare resource utilization among children and adolescents with achondroplasia: an observational cohort study using Optum’s de-identified Clinformatics® Data Mart Database

Abraham Pranav , Miles Gandarvaka , Petruski-Ivleva Natalia , I. Berger Kenneth

Background: Achondroplasia is the most common skeletal dysplasia associated with inhibited growth development and disproportionately short stature; morbidity and complications are apparent at birth and continue throughout life. We assessed the clinical and healthcare resource utilization (HCRU) burden of achondroplasia in US children and adolescents.Methods: This retrospective study assessed children and adolescents (age...

Objectives: Osteogenesis imperfecta (OI) is a skeletal dysplasia affecting 1–2 individuals per 20,000 live births, but the burden of disease in children and adolescents remains unclear. We assessed the clinical and healthcare resource utilization (HCRU) burden of OI in US clinical practice.Methods: This retrospective cohort study included children and adolescents (aged ≤19 years) with OI (≥1 inpatient claim, ...

The Story of a de novo Heterozygous HNF1A Mutation

Ponmani Caroline , Banerjee Kausik

Background: MODY is characterised by an early onset of diabetes and a positive family history of diabetes with an autosomal dominant mode of inheritance. We report a 15 year girl with a HNF1A mutation who presented with MODY without a positive family history.Objective and hypotheses: HNF1A-MODY is often misdiagnosed as type 1 or type 2 diabetes. Genetic confirmation of MODY in insulin-treated patients helps in making changes in the treatment modality as ...
