Introduction: Recently the incidence of type 2 diabetes was explosively increased in children and adolescents. The underlying mechanism of childhood-onset type 2 diabetes mellitus may be different to the adult-onset type 2 diabetes. Therefore, it is useful to conduct genetic study in children with type 2 feature to understand underlying cause of glycemic dysregulation as well as for the management of diabetes mellitus.Case</stron...

Background: GH insensitivity is caused by disturbances of GH receptor function or inability to transduce the hormone signal. Affected children are severely growth retarded and may also present immune complications when the transducer STAT5B is defective. Only autosomal-recessive STAT5B mutations have been described to date.Clinical case: Two male 14.5 year monozygotic twins presented with heights of 131.5 cm (−5.3 SDS). Bone age of the ind...

Background: Heterozygous loss-of-function variants of fibroblast growth factor receptor 1 (FGFR1) are genetic causes of Combined Pituitary Hormone Deficiency (CPHD), Kallmann syndrome (KS) with anosmia/iposmia, Congenital Hypogonadotropic Hypogonadism (CHH) with normosmia and Septo-Optic Dysplasia. It is well-known that these variants are the main genetic factor underlying the development of CHH and KS; however, they have only occasionally been identified in C...

Objective: To determine the mutation in the SRY gene in a 46,XY complete gonadal dysgenesis patient with bilateral gonadoblastoma and coexisting dysgerminoma. Evaluate the functional consequence of mutated SRY gene in the tumor risk of 46,XY DSD.Methods and Materials: The proband was a 13-year-old girl who was admitted for examination due to undeveloped secondary sexual characteristics. She had no breas...

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...

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...

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...

Background: Congenital Hyperinsulinism (CHI) is the most frequent cause of severe, persistent hypoglycemia in children. Persistent hypoglycemia places patients at risk for adverse clinical outcomes, and current guidelines recommend maintaining plasma glucose >3.9mmol/l. CHI patients often have substantial, residual hypoglycemia and fail to meet treatment goals with currently available standard of care (SOC) therapies. In this study, we aimed to characterize...

Background: Congenital hyperinsulinism (CHI) is a chronic and complex rare endocrinopathy with dysregulated insulin secretion causing severe and recurrent hypoglycemia resulting in adverse neurologic and developmental sequelae in children. Current treatment options are limited and often inadequate to treat CHI. Dasiglucagon (DASI), a glucagon analog administered by subcutaneous continuous infusion, has demonstrated reduction in glucose infusion rate (GIR) in P...
