Abstract Achondroplasia is the most common disproportionate short-stature skeletal dysplasia. Features associated with achondroplasia are rhizomelia, macrocephaly, midface hypoplasia, and typical cognition. Potential medical complications include foramen magnum stenosis, hydrocephalus, middle ear dysfunction, obstructive central sleep apnea, spinal stenosis genu varum. Recently, vosoritide, a CNP analogue, was approved by FDA primary indication of increasing linear growth in all children...

Abstract Background Achondroplasia, a disease characterized by disproportionate short stature and increased morbidity, affects daily function quality of life over the lifetime individual. However, data are limited on its economic impact, especially related to healthcare resource utilization (HCRU) associated costs. This study aimed characterize clinical impact achondroplasia in US relative matched non-achondroplasia controls stratified pediatric adult populations. Methods retrospective used...

Introduction: Short stature can lead to physical limitations and socioemotional effects limiting a child parents’ quality of life (QoL). This study investigates the impact hypochondroplasia other genetic causes (ACAN, NPR2 mutations RASopathy) short on QoL. Methods: Parents participants in an ongoing Phase II clinical trial vosoritide children with selected completed Quality Life Stature Youth (QoLISSY) survey.

Introduction Type 1 pseudohypoaldosteronism (PHA) consists of resistance to aldosterone. Neonatal presentation is characterized by salt wasting, hyperkalemia, and metabolic acidosis with high risk mortality. PHA can be autosomal dominant (renal type 1) or recessive (systemic 1). Renal feasibly managed supplementation; however, systemic tends have more severe electrolyte imbalance refractory treatment. Case Presentation We present a case 3-year-old girl 1, diagnosed confirmed molecularly in...

Introduction: Vosoritide is a C-type natriuretic peptide (CNP) analog that binds its receptor on chondrocytes, promoting growth by inhibiting the ERK1/2-MAPK pathway. We previously reported results of phase II study in children with hypochondroplasia. led to an average increase annualized height velocity (AHV) 1.81 cm/year and gain 0.36 standard deviation (SD) over 12 months. present here pharmacokinetic/pharmacodynamic (PK/PD) data from this examine correlations between these parameters...

We report three patients with elevations of propionylcarnitine (C3), one without 2-methylcitrate and 3-hydroxypropionate in urine organic acid analysis, the other two showing only mild elevations, all whom were subsequently confirmed to have propionic acidemia by molecular analysis PCCA PCCB genes. To date, they had a clinical course. These cases illustrate importance considering high C3 as biochemical abnormality diagnosis acidemia. Since may be overlooked considered non-diagnostic...

Background. McCune-Albright syndrome (MAS) is characterized by hyperpigmented macules, endocrinopathies, and fibrous dysplasia. Hyperthyroidism the second most common endocrinopathy in MAS its management challenging, particularly among infants toddlers. Traditionally, young have been treated with antithyroid medications, but remission likely these medications severe side effects affect control of other endocrinopathies. Thus, it reasonable to consider permanent treatment options at an...

Summary Iodine nutrition is a growing issue within the USA due to newer trends of non-iodized salts. There are no recent reviews looking at current state iodine deficiency-induced hypothyroidism in children USA. We performed retrospective chart review our tertiary pediatric endocrine clinic; four met diagnostic criteria for deficiency defined by low urine level. further characterized severity disease, risk factors, goiter, thyroid labs and antibodies. All cases had significant goiter were...

Abstract Germline pathogenic variants in the RAS/mitogen‐activated protein kinase (MAPK) signaling pathway are molecular cause of RASopathies, a group clinically overlapping genetic syndromes. RASopathies constitute wide clinical spectrum characterized by distinct facial features, short stature, predisposition to cancer, and variable anomalies nearly all major body systems. With increasing global recognition these conditions, 8th International Symposium spotlighted perspectives on care...

Abstract Children with skeletal dysplasias have not been consistently managed by pediatric endocrinologists despite the recognized expertise of these practitioners in managing genetic growth disorders. Growth-altering treatments broadened role endocrinologist to manage and sometimes become primary coordinators for disorders such as Turner syndrome Prader-Willi syndrome. We illustrate how recent advances understanding pathophysiology development targeted provide an opportunity further expand...
