A small RNA molecule called miR-23a can prevent neuron degeneration and muscle wasting by acting as a protective modifier in cellular and animal models of spinal muscular atrophy (SMA), a study says. The study, “AAV9-Mediated Delivery of miR-23a Reduces Disease Severity in Smn2B-/SMA Model Mice,” was published in…

Elevated levels of the protein alpha-COP, involved in cellular transport and self-cleansing processes, extended survival in a mouse model of severe spinal muscular atrophy (SMA) without altering levels of the survival motor neuron (SMN) protein, according to a recent study. These results suggest this protein can modify SMA,…
People with rare diseases know that the right government policies can make a big difference in the quality of their own lives, and those of their caregivers. But most lawmakers aren’t experts in even one well-known disease — let alone the world’s estimated 7,000 rare disorders. So how does the…
Ontario has expanded publicly funded access to Spinraza (nusinersen) to cover spinal muscular atrophy (SMA) types 2 and 3. The decision specifically covers presymptomatic patients with two or three copies of the SMN2 gene; patients with SMA for less than six months, two SMN2 copies, and…
Tina and Torence Anderson’s sixth and youngest child, Malachi, came into the world on July 31, 2015. “When he was born, he was normal,” Tina said in a phone interview with SMA News Today. But eight weeks later,…
Now that the U.S. Food and Drug Administration has given its blessing to the AveXis gene therapy Zolgensma for children up to 2 years old with spinal muscular atrophy, the company hopes to win similar approval from the European Medicines Agency (EMA) later this year. AveXis,…
Top-line results from a Phase 1 trial showed that SRK-015 had a positive safety profile and durable effects in healthy adult volunteers. These findings supported the start of the Phase 2 study TOPAZ (NCT03921528) to evaluate SRK-015’s efficacy to improve motor function of SMA patients. TOPAZ is currently…
