Abstract Background Costello syndrome (CS) and cardio-facio-cutaneous (CFCS) belong to the RASopathies, a group of neurodevelopmental disorders with skeletal anomalies. Due their rarity, characterization musculo-skeletal phenotype in both has been poorly characterized. Patients methods Herein we reported data on orthopedic findings functional status large sample CS CFCS patients. Thirty-four pa...

Monogenic disorders causing systemic lupus erythematosus represent a small subset of cases. Type-1 interferonopathies, like spondyloenchondrodysplasia with immune dysregulation constitute an important functional category monogenic lupus. Apart from autoimmune disorders, neurological and skeletal abnormalities are additional manifestations observed in this disorder. A young female presented seiz...

Abnormalities in the integral components of bone, including bone matrix, bone mineral and bone cells, give rise to complex disturbances of skeletal development, growth and homeostasis. Non-specific drug delivery using high-dose systemic administration may decrease therapeutic efficacy of drugs and increase the risk of toxic effects in non-skeletal tissues, which remain clinical challenges in th...

There are more than 450 well-characterized skeletal dysplasias classified primarily on the basis of clinical, radiographic, and molecular criteria. In the latest 2010 revision of the Nosology and Classification of Genetic Skeletal Disorders, an increase from 372 to 456 disorders had occurred in the four years since the classification was last revisited in 2007. These entities in total represent...

Genetic skeletal disorders (GSD) involving the skeletal system arises through disturbances in the complex processes of skeletal development, growth and homeostasis and remain a diagnostic challenge because of their clinical heterogeneity and genetic variety. Over the past decades, tremendous effort platforms have been made to explore the complex heterogeneity, and massive new genes and mutation...

Genetic disorders of the skeleton or skeletal dysplasias are a clinically diverse and genetically heterogeneous group of connective tissue disorders affecting skeletal morphogenesis and development. More than 200 different entities have been described. Despite the growing availability of molecular testing for several of these disorders, the diagnosis of a skeletal dysplasia still relies primari...

Introduction: Satellite cells are known as the main regenerative cell type in skeletal muscles. Our study established a modified digestion and preplating method for the isolation of slow or weak adherent cells for the enrichment of satellite cells. Low-survival rate of these primary stem cells prompted us to address whether cell culture medium substitution might change cell viability status. M...

The skeletal dysplasias form a large group of hereditary disorders characterized by abnormal growth and malformations of bone and cartilage. The clinical severity ranges from mildly affected short stature to lethal forms. Spranger classified approximately 200 different skeletal dysplasias in 1992, based on the clinical and radiographic features and the mode of genetic transmission. Etiopathogen...

A hospital based study of skeletal dysplasias was conducted over a period of 2 years in Davangere, Karnataka, in which 169 cases of skeletal dysplasias were studied. One hundred were osteochondrodysplasias and were grouped according to international classification of osteochondrodysplasias. Among the individual cases, osteogenesis imperfecta (13 cases) had the maximum representation. Several ca...
