New HDAC inhibitor AR42 shows promise in SMA mouse model

A histone deacetylase (HDAC) enzyme inhibitor called AR42 was found to prolong survival and ease motor symptoms in a mouse model of spinal muscular atrophy (SMA). While scientists initially expected the experimental molecule to show benefits by helping to boost levels of the SMN protein that’s deficient in SMA,…

Surveys show how SMA care was aided, hindered by pandemic

The COVID-19 pandemic made it more difficult  for many people with spinal muscular atrophy (SMA) to access needed healthcare, a study highlights. At the same time, the pandemic prompted new approaches to facilitating care and running clinical trials, such as the widespread adoption of telehealth, which brings health providers…

New patient-derived cell models may advance SMA, SMARD1 study

Researchers have developed new patient-derived cell models of spinal muscular atrophy (SMA) caused by SMN1 mutations as well as the more rare spinal muscular atrophy with respiratory distress type 1 (SMARD1). The cells exhibited structural abnormalities consistent with SMA which could be rescued with gene therapies. Scientists believe the new…

Muscle ultrasound may help to monitor SMA progression: Study

Muscle abnormalities observed with ultrasound imaging correlated with motor function in people with spinal muscular atrophy (SMA) in a recent study. While the findings varied somewhat by muscle group and SMA type, ultrasound data generally indicated SMA patients exhibited muscle atrophy and signs of fat and connective tissue…
