Background: Achondroplasia is a skeletal dysplasia being the most common cause of rhizomelic dwarfism.Case presentation: We present a 10 years old boy who was first diagnosed prenatally. He had a mutation c1138G>A in the gene FGFR3 in a heterozygotic constellation. His IGF1 levels and IGFBP3 were normal. Two stimulation tests for GH were performed with normal levels of the hormone. His psychomotor development was adequate for his age except for speec...

Background: Endocrine disorders associated with tall stature in childhood are frequently evaluated by Pediatric Endocrinologists. The most common non-endocrine genetic cause of tall stature, Marfan syndrome, is a rare autosomal dominant genetic condition of the connective tissue, which presents with specific dysmorphic features, including thin physique, long extremities and normal growth rate. Little is known regarding the association of Marfan syndrome with o...

Introduction: 17q12 deletion syndrome is associated with an enlarging phenotype, the most frequent clinical findings being renal and genitourinary malformations, diabetes mellitus (β-cell developmental defect) and exocrine pancreas deficiency, variable cognitive impairment with dysmorphic features.Diabetes, known as MODY 5 (maturity-onset diabetes of the young), is an autosomal dominant monogenic type and the most commonly identi...

Introduction: The heterozygous activating mutations in the KCNJ11 and ABCC8 are the commonest causes of permanent neonatal diabetes mellitus (PNDM). The most severe clinical form of NDM is DEND syndrome. Besides diabetes mellitus such patients show severe developmental delay, hypotonia and therapy-resistant epilepsy. To our knowledge only some cases of DEND syndrome due to ABCC8 mutations are sulfonylurea-responsive. Here we report case of DEND syndrome due t...

Introduction: Beckwith-Wiedemann Syndrome (BWS) is a rare genetic disorder that could be associated with embryonal tumours. Genotype based categorisation of patients enables better screening strategies. We present a patient with BWS who developed atypical congenital hepatoblastoma and atypical Wilms tumour in infancy.Case Report: A 2 day old infant was referred with recurrent hypoglycaemia and high intravenous glucose requirement [>12 mg/kg/min]. He ...

Case Report: A 13-year old male presented to a dental office for evaluation of prognathism. After evaluation, his dentist referred him to pediatric endocrinology. He had no significant past medical history. He denied any signs or symptoms associated with any hormonal deficit or excess, as well as headaches or visual disturbances. Denied excessive growth of hands or feet. Parents reported that he had been having pubic and axillary hair, mild acne, and significant growth for the...

Background: Chimerism is the phenomenon of two or more genetically distinct cell lines (originating from different zygotes) in the same individual. In situations when the sex of the fertilised eggs is disparate, it can lead to intersex phenotypes.Objective and hypotheses: We report a case of ovotesticular disorder of sexual development with chimerism resulting from a twin pregnancy (not involving assisted reproductive technologies).<p class="abstext"...

Introduction: X-linked hypophosphataemic rickets (XLH), due to mutations in the PHEX (Phosphate-regulating Endopeptidase homolog; X-linked) gene, causes reduced bone and dentin mineralisation and decreased renal phosphate reabsorption. Mosaic PHEX mutations are reported only in a few case reports.We report three male cases, with mosaic pathogenic PHEX variants, showing importance of considering this in the diagnosis of XLH.Case 1 pre...

Introduction: Spinal muscular atrophy (SMA) is an autosomal recessive neurodegenerative disease. In 2016, nusinersen (Spinraza) was approved by the FDA. The first AAV9-based gene therapy (Zolgensma), was approved by the FDA (2019) for the treatment of infants with SMA. We report an SMA case with recurrent hypoglycemic events after gene therapy.Case Report: A 22 months old boy, with SMA type 1 was born at term by CS for fetal bradycardia....

Introduction: Extreme hypertriglyceridaemia is uncommon in the paediatric population but can have devastating consequences. It can lead to acute pancreatitis, cutaneous eruptive xanthomas and lipaemia retinalis. Severe hypertriglyceridemia likely accounts for 1-10% of acute pancreatitis cases in adults but there is limited data in children. We report a case of new-onset type 1 diabetes mellitus (T1DM) presenting in diabetic ketoacidosis (DKA) with acute pancre...
