objective a 4-month-old female with osteogenesis imperfecta (oi) type ii was admitted in picu of our center due to severe respiratory distress and fever with a diagnosis of severe pneumonia, and mechanical ventilation was initiated. due to severe hypotonia, ncv and emg were performed, and spinal muscular atrophy (sma) type i was diagnosed.

The expansion of CAG repeats encoding glutamine (polyQ) causes, to date, 9 late-onset progressive neurodegenerative disorders, including Huntington disease, spinobulbar muscular atrophy, dentatorubral-pallidoluysian atrophy, and spinocerebellar ataxias 1, 2, 3, 6, 7, and 17. Although many studies using both knockout and transgenic mouse models suggest that a toxic gain of function is central to...

Polyglutamine diseases are a family of neurodegenerative conditions that each derive from a CAG triplet repeat expansion in a specific gene. This produces a pathogenic protein that contains a critically expanded tract of glutamines. These prototypical protein misfolding disorders include Huntington disease, spinobulbar muscular atrophy, dentatorubral-pallidoluysian atrophy and several spinocere...

OBJECTIVES Studies involving patients with spinobulbar muscular atrophy (SBMA), which is often referred to as Kennedy's disease, similar to those involving patients with progressive muscular disease (PMD), are rare. This paper reports a case study involving the use of Korean medicine to treat a patient with SBMA. METHODS We treated a patient with SBMA with unique symptoms by using various kin...

abstract objective autosomal recessive spinal muscular atrophy (sma) is, after cystic fibrosis, the second most common fatal monogenic disorder and the second most common hereditary neuromuscular disease after duchenne dystrophy. the disease is characterized by degeneration of anterior horn cells leading to progressive paralysis with muscular atrophy. depending on the clinical type (werdnig- ho...

Expansion of polyglutamine (polyQ) beyond the pathogenic threshold (35-40 Gln) is associated with several neurodegenerative diseases including Huntington's disease, several forms of spinocerebellar ataxias and spinobulbar muscular atrophy. To determine the structure of polyglutamine aggregates we perform replica-exchange molecular dynamics simulations coupled with the optimized potential for ef...

Spinobulbar muscular atrophy (SBMA) is a neurodegenerative disease caused by expansion of a polyglutamine tract in the androgen receptor (AR). This mutation confers toxic function to AR through unknown mechanisms. Mutant AR toxicity requires binding of its hormone ligand, suggesting that pathogenesis involves ligand-induced changes in AR. However, whether toxicity is mediated by native AR funct...
