A range of genetic mutations associated with spinal muscular atrophy (SMA) were linked to abnormal activation of the immune system in fly models, which a team of U.S. researchers believe could be a mechanism that contributes to neurodegeneration in the rare disease. Altogether, the evidence indicated that these exacerbated…
More high-quality studies are needed to understand the mechanisms of fatigue in spinal muscular atrophy (SMA) and to identify which, if any, SMA therapies or interventions might be able to truly ease the common but often troublesome symptom. That’s according to a new review study that found that…
Tiny carriers of cellular cargo called extracellular vesicles (EVs) — isolated from stem cells found in fat tissue — improved motor performance and slowed motor nerve cell degeneration in a mouse model of spinal muscular atrophy (SMA), according to recent research. Researchers believe these so-called ASC-EVs may offer the…
The troponin T (TNT) protein — a marker of heart muscle damage — was elevated in the bloodstream of more than half of spinal muscular atrophy (SMA) patients, especially in younger children with more severe disease, a recent analysis shows. Another heart-specific form of troponin called troponin I (TNI)…
New research has identified mechanisms by which Evrysdi (risdiplam), an approved spinal muscular atrophy (SMA) therapy, has more specific effects at its target gene than branaplam, a similar molecule that was investigated as a possible SMA treatment, but later discontinued. Both molecules modify a process called splicing in…
The practice of vacuum swallowing, a maneuver involving effort that’s intended to aid the movement of food through the throat, helped a man with spinal muscular atrophy (SMA) who had dysphagia, a swallowing impairment. “This is the first report of successful instruction and acquisition of vacuum swallowing in a…
Implementing the global compassionate use program (CUP) that enabled more spinal muscular atrophy (SMA) patients to access Evrysdi (risdiplam) required close collaboration with patient advocacy groups and careful consideration of local regulations, according to a new report. Taking such steps was key in helping the CUP to reach…
Despite treatment with leuprorelin over three years, all spinal and bulbar muscular atrophy (SBMA) patients in a study in Korea continued to experience declines in motor function, a new study found. However, those individuals with less disability at the start of treatment experienced slower disease progression, “indicating a more…
Infants with suspected spinal muscular atrophy (SMA) who are directly referred to an SMA care center may experience shorter wait times than those referred to general neurology practices, according to a survey of these specialists deployed by Cure SMA. While both types of practices reported using triage methods…
Genetic alterations related to two genes, SMN2 and NAIP, could help to predict the severity of spinal muscular atrophy (SMA), according to a recent analysis. Among patients with SMA type 1 and type 2 in Egypt, all of whom had standard disease-causing mutations in the SMN1 gene, fewer copies…
