Introduction: Growth restriction (GR) comprises ~50% of new patient referrals to paediatric endocrine clinics with <20% receiving a clear diagnosis. Enhanced genetic testing and stratification leading to tailored clinical care is a fundamental need. Whole-genome sequencing (WGS) was offered to patients recruited to the 100,000 Genomes Project (100 KGP), leading to new diagnoses in ~25% of all rare disease participants. The analysis pipeline uses disease-spe...

Introduction: Growth failure is a side effect of HSCT in children. This study aims to evaluate the growth trajectory in a series of boys who underwent allogeneic HSCT for childhood cancer in pre-puberty and reached final height (FH).Methods: We evaluated auxological parameters, mid-parental target height (TH), serum testosterone, and insulin-like growth factor 1 (IGF-1 SDS) levels of 19 boys who underwent allogeneic HSCT...

Background: Achondroplasia is the most common form of osteochondrodysplasia, characterized by abnormal bone and cartilage growth leading to dwarfism and short limbs. It is caused by autosomal dominant mutations in the FGFR3 gene, leading to constitutive activation of the FGFR3 receptor, inhibiting chondrocyte proliferation and disrupting normal bone growth. Vosoritide is a 39-amino acid CNP peptide analogue, indicated for treating achondroplasia in patients ov...

Aim and Method: Achondroplasia is the most common form of short-limbed dwarfism, characterized by mutations in the FGFR3 gene. Vosoritide, a C-type natriuretic peptide analog, has shown promise in promoting linear growth in children with achondroplasia. This study aims to present the real-life experiences of using vosoritide in children diagnosed with achondroplasia.Method and Results: A prospective study was conducted o...

Background: Achondroplasia (ACH) is an autosomal dominant condition, resulting from pathogenic missense FGFR3 (fibroblast-growth-factor receptor-3) variants. Foramen magnum stenosis (FMS) is a severe complication, with infants and younger children being at higher risk. FMS may be asymptomatic or cause cervical-medullary compression (CMC), presenting with hydrocephalus, hypotonia or hypertonia, central sleep apnea and sudden death. The scope of the stu...

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...

Background: Aggrecan is the most abundantly expressed extracellular matrix proteoglycan in growth plate cartilage and is crucial for its normal functioning. Heterozygous, loss-of-function mutations in the aggrecan gene (ACAN) cause autosomal dominant short stature with advanced bone age, early-onset osteoarthritis and intervertebral disc disease (SSOAOD; OMIM#165800). ACAN mutations are a relatively frequent finding of approximately 2% in coh...

Introduction: Isotretinoin is used for treatment of dermatological diseases, such as severe acne. It’s also recommended for treatment of high-risk neuroblastoma and pediatric medulloblastoma, but in these cases higher doses are necessary.Case report: A 12-year-old male patient with poorly differentiated embryonal origin carcinoma in the posterior fossa and implants in the neuroaxis. Next-generation sequencing genet...

Objective: Serum Anti-Mullerian Hormone (AMH) and Inhibin-B (INHB) levels were assessed in patients with Turner Syndrome (TS) of different karyotypes, and ovarian reserve function was evaluated by AMH and INHB in patients with TS.Methods: From January 2021 to January 2024, 52 patients diagnosed with TS aged 4-17 years were diagnosed in the Department of Endocrinology, Genetics and Metabolism of Jiangxi Provincial Childre...
