Case Report: A Novel Homozygous Variant of the Gene in Rare Pycnodysostosis.

Pycnodysostosis (PD) is a rare autosomal recessive skeletal dysplasia from impaired bone resorption due to osteoclastic dysfunction. The features of PD are deformity of the skull, maxilla, and phalanges; osteosclerosis; and bone fragility. We describe the case of a patient with complaints of multiple fractures of the lower extremities in the anamnesis and pain in the lower extremities, cervical spine, and shoulder girdle during physical exertion.

Bone fracture after minor trauma in Pyle's disease: A rare case in an adult.

Pyle's disease (PD) is a rare autosomal recessive metaphyseal dysplasia with approximately 30 reported cases and has recently gained interest due to its association with specific genes. While most cases are diagnosed in childhood and are asymptomatic, we present the case of a 39-year-old woman who presented to the Emergency Department with left knee pain, patellar fracture, and "Erlenmeyer flask" deformity. Retrospective review of imaging studies and medical history revealed the symmetric and systemic nature of the skeletal disorder, confirming the diagnosis of PD.

Impaired salivary gland function in children with osteogenesis imperfecta: a case-control study.

This study aims to evaluate the therapeutic efficacy and safety of Janus kinase 1 (JAK1) inhibitor abrocitinib in patients with SAPHO syndrome.

Methods: We presented a patient with SAPHO syndrome with accelerated disease progression who did not respond to traditional therapies.

Expert consensus for the management of patients with achondroplasia in treatment with vosoritide.

Introduction: Patients with achondroplasia present, in addition to disproportionate short stature, multiple manifestations that require a comprehensive approach. The present consensus of experts in Spain responds to the need to establish clear guidelines for the management of achondroplasia with the introduction of a new treatment, vosoritide.

Material And Methods: A panel of six experts in achondroplasia participated in the development of the consensus.

Lung function in adult patients with osteogenesis imperfecta: a cohort study.

Background: Osteogenesis imperfecta (OI) is a rare hereditary bone disease resulting from a defect in collagen synthesis or processing, leading to bone fragility, frequent fractures and skeletal deformities. OI is associated with increased respiratory morbidity and mortality, but the mechanisms of lung involvement are poorly understood, and there are no data on the natural history of lung function. We studied lung function over time in a cohort of adult OI patients at one center.

Syndrome-informed phenotyping identifies a polygenic background for achondroplasia-like facial variation in the general population.

Human craniofacial shape is highly variable yet highly heritable with numerous genetic variants interacting through multiple layers of development. Here, we hypothesize that Mendelian phenotypes represent the extremes of a phenotypic spectrum and, using achondroplasia as an example, we introduce a syndrome-informed phenotyping approach to identify genomic loci associated with achondroplasia-like facial variation in the general population. We compare three-dimensional facial scans from 43 individuals with achondroplasia and 8246 controls to calculate achondroplasia-like facial scores.

Atypical presentation of Dyggve-Melchior-Clausen disease in a Moroccan child without developmental delay and intellectual disabilities.

Background: Dyggve-Melchior-Clausen (DMC) disease is a rare autosomal recessive disorder primarily characterized by spondylo-epimetaphyseal dysplasia, intellectual disability, and distinctive facial features. Patients typically present with severe developmental delays and cognitive impairments, defining features of the syndrome.

Methods And Results: This case report examines a 13-year-old Moroccan child diagnosed with DMC disease, presenting classical skeletal abnormalities, including spondylo-epimetaphyseal dysplasia, as confirmed through exome sequencing.

The IMPACT Survey: the humanistic impact of osteogenesis imperfecta in adults.

Background: The IMPACT Survey explored the humanistic, clinical, and economic burden of osteogenesis imperfecta (OI) on individuals with OI, their families, caregivers, and wider society. Two previous publications report research methodology, initial insights of the survey, and cost of illness of OI. Here, we present data on the impact of OI on the quality of life (QoL) of adults with OI and explore potential drivers of this impact.

Spectrum of IDH-mutant tumors in Ollier-Maffucci disease: the triple interaction theory.

We propose to refine our understanding of the pathophysiology underlying the tumor spectrum observed in patients with Ollier disease (OD) and Maffucci syndrome (MS). On one hand, assuming that all IDH-mutated tumors (as well as enchondromas) observed in OD-MS patients derive from one IDH-mutant cell giving rise to different lineages, the observation of different tumors arising in organs deriving from the neuroectoderm, mesoderm and endoderm points towards a very early post-zygotic event for the IDH mutation. To explain then that the spectrum of IDH-mutated tumors is restricted to some types of tumors, we propose the following hypothesis: - First, we posit that not every mutated cell of the lineage will "express" the IDH mutant phenotype.

Myriad of congenital excavated optic disc anomalies in achondroplasia.

Achondroplasia is a genetic condition resulting from specific disruptions in the formation of endochondral bone. Telecanthus, exotropia, angle anomalies and cone-rod dystrophy have been observed as associated ophthalmic features in patients with achondroplasia. Here, we present a case of achondroplasia associated with unique ocular features including telecanthus, esotropia and bilateral microphthalmos.

[Achondroplasia : New era of orthopedic treatment?].

Achondroplasia is the most common skeletal dysplasia. With the development of new growth-promoting drug treatment for children and adolescents with achondroplasia, multidisciplinary care has become increasingly more important. In addition to orthopedic care, a specialized team comprised of pediatrics/endocrinology, radiology, neurosurgery, otorhinolaryngology, anesthesiology, physiotherapy, psychology and other disciplines is necessary to develop and implement a holistic concept to improve the quality of life for individuals affected by achondroplasia.
