A new large-scale genetic screening technique for spinal muscular atrophy (SMA) called comprehensive SMA analysis, or CASMA, was more effective at detecting disease-related mutations in carriers than standard approaches, a study reports. CASMA “is a simple and…

Treatment for 10 months with Spinraza (nusinersen) normalized the activity of 38 genes in adults with spinal muscular atrophy (SMA), a genetic study showed. Among the normalized genes were those involved in immune signaling pathways —…

Nearly two-thirds of adults in South Korea with spinal muscle atrophy (SMA) type 2 or type 3 were initially misdiagnosed, according to a recent study. In type 2 cases, the primary misdiagnosis…

The gene therapy Zolgensma (onasemnogene abeparvovec-xioi), given as a sole treatment, improves motor skills and preserves lung health and feeding abilities in infants with spinal muscular atrophy (SMA) type 1, according to a real-world study. Despite such benefits to patients treated at a mean age of 7.5 months,…

Surgery to correct scoliosis, a sideways curvature of the spine, slowed lung function decline in people with spinal muscular atrophy (SMA) type 2 and 3 who had yet to receive treatment, a study focusing on secondary outcomes reported. While all participants reported overall satisfaction with posture and physical…

The use of ultrasound to guide the administration of Spinraza (nusinersen) injection into the spinal canals of adults with spinal muscle atrophy (SMA) significantly reduced the number of needle redirections compared with a standard, landmark-based approach, according to a clinical trial. Among patients with spinal deformities, ultrasound…

Treatment with Zolgensma (onasemnogene abeparvovec-xioi) improves motor function in children with spinal muscular atrophy (SMA) who carry at least four copies of the so-called backup SMN2 gene, according to real-world data from the RESTORE patient registry. SMA children treated with the approved gene therapy achieved several motor…

An infant was diagnosed with Down syndrome coexisting with spinal muscular atrophy (SMA) type 1, a case study reported. “The coexistence of [Down syndrome] and SMA poses unique challenges due to overlapping clinical features,” the researchers wrote in the case study, “A Rare Genetic Intersection:…

A milder form of spinal muscular atrophy (SMA) was discovered in two siblings who carry a common mutation in one SMN1 gene and a rare mutation in the other, a new study by Mayo Clinic researchers reported. Skin cells from the brother and sister showed higher levels of…

Treatment with Spinraza (nusinersen) extended the distance adults with spinal muscular atrophy (SMA) type 3 could walk during a six-minute walking test (6MWT), but they walked farther during the first minute than the sixth, a sign of fatigability despite treatment, a study suggests. “The increase in 6WMT…
