Purpose Of Review: This review highlights how skeletal dysplasias are diagnosed and how our understanding of some of these conditions has now translated to treatment options.
Recent Findings: The use of multigene panels, using next-generation sequence technology, has improved our ability to quickly identify the genetic etiology, which can impact management. There are successes with the use of growth hormone in individuals with SHOX deficiencies, asfotase alfa in hypophosphatasia, and some promising data for c-type natriuretic peptide for those with achondroplasia. One needs to consider that a patient with short stature has a skeletal dysplasia as options for management may be available.

Osteogenesis imperfecta is a genetic condition with improperly or inadequately produced Type I collagen. Manifestations include bowing deformities, fractures, hydrocephalus, respiratory insufficiency, and feeding difficulty. Moderate or severe OI is often diagnosed prenatally based on ultrasound findings and genetic testing may be labeled as lethal.

Background: This cross-sectional study investigated mental health conditions, physical functioning, and health-related quality of life (HRQOL) in adults with short-statured skeletal dysplasia conditions across three centres; in New York, Newcastle-upon-Tyne and Norway.
Methods: Questionnaires were sent to patients registered at the centres or distributed to adults attending clinics. The questionnaires included demographics, medical history, depression (PHQ-8), anxiety (GAD-7), pain catastrophizing, activities of daily living (HAQ), and HRQOL (SF 36/RAND-36 and PROMIS-29).

Mutations in the anoctamin5 (ANO5) gene can lead to musculoskeletal disorders, with monoallelic (autosomal dominant) mutations typically presenting as skeletal abnormalities known as Gnathodiaphyseal dysplasia (GDD). Clinically, GDD is characterized by thickened cortices of long bones and mandibles, narrowed medullary cavities, and increased bone fragility. While autophagy is necessary in regulating bone formation, the specific relationship between ANO5 and autophagy remains poorly understood.

Background: Achondroplasia is one of the most prevalent forms of skeletal dysplasia. Lifelong follow-up by an experienced multidisciplinary team is required, particularly during the first 2 years. In 2021, international consensus recommendations and guiding principles were published by two groups.

Hypophosphatasia (HPP) is a congenital skeletal dysplasia. Enzyme replacement therapy (ERT) improves survival and bone mineralization of patients with perinatal severe HPP. However, there are few reports of ERT in patients with perinatal benign HPP, and its long-term efficacy remains unclear.
