Outcomes of combination therapy with nusinersen, onasemnogene abeparvovec, and risdiplam over 3.5 years in a patient with prenatally diagnosed spinal muscular atrophy type 0: A case report.

Brain & development2026 Apr

Recently introduced disease-modifying therapies have markedly improved survival and motor outcomes, particularly when initiated presymptomatically or in the early symptomatic stage. However, reports on treatment of the most severe form, SMA type 0, remain extremely limited. We report a patient with prenatally diagnosed spinal muscular atrophy type 0 who was treated with nusinersen and onasemnogene abeparvovec as early and as safely as possible, followed by risdiplam, for further motor acquisition. With continuous physiotherapy, the patient achieved independent walking at 2 years 11 months and showed sustained development without swallowing or respiratory difficulties up to 3.5 years of age. Early intervention with combined use of disease-modifying therapies may be beneficial for patients with severe spinal muscular atrophy phenotypes. However, since evidence of efficacy and safety of combination therapy is still lacking, great caution should be paid to this treatment strategy, taking the patient's clinical status into account.

Spinal Muscular Atrophy-Survivorship and Care in a New Therapeutic Landscape.

Pediatric neurology2026 Feb 16

Spinal muscular atrophy (SMA) is an inherited lower motor neuron disorder resulting from autosomal recessive variants in the survival motor neuron protein (SMN1) located on chromosome 5q. Previously the most common inherited cause of infant mortality, the development of SMN-restoring disease-modifying therapies combined with the expansion of newborn screening programs for SMA, have improved motor function and survival. With improved function and survival, new questions are emerging around the role of combining multiple SMN-restoring therapies or SMN-restoring therapies with newer therapeutic agents targeting other pathways such as neuromuscular transmission or muscle growth. Additionally, with the earlier initiation of SMN-restoring disease-modifying therapies, the assessment of long-term treatment durability, motor function attained and retained, neurodevelopment, and potential emerging phenotypes or symptoms in individuals living with SMA will need to be explored.

Electrophysiological assessment of motor unit loss in adult spinal muscular atrophy types III and IV: a multicenter national study comparing MUNIX, CMAP, and MUSIX.

Journal of neurology2026 Mar 02

Spinal muscular atrophy (SMA) types III and IV are the most common late-onset forms, and they progress slowly, making the identification of sensitive biomarkers critical. The Motor Unit Number Index (MUNIX) estimates motor unit loss and may complement traditional electrophysiological measurements such as Compound Muscle Action Potential amplitudes (CMAP). However, their respective performances have never been directly compared in adult SMA. In a French multicenter study (NCT04690998), 71 adult patients with SMA and 24 healthy controls underwent clinical and electrophysiological evaluation. MUNIX, CMAP, and Motor Unit Size Index (MUSIX) were recorded in four muscles, and sum scores (SumMUNIX, SumCMAP, SumMUSIX) were calculated. Reliability was assessed using intraclass correlation coefficients (ICCs), and associations with functional outcomes were explored. MUNIX and CMAP effectively distinguished SMA patients from controls, showing strong test - retest reliability. MUNIX showed the highest discriminative performance (AUC = 0.92), while CMAP demonstrated the strongest and most consistent associations with clinical severity. In multivariate analyses, only CMAP remained independently associated with all functional and strength measures, whereas MUNIX and MUSIX lost significance. MUNIX demonstrated the highest discriminative performance among biomarkers for differentiating SMA from controls, indicating early motor unit loss even when CMAP values were within normal limits. However, disease burden and functional impairment were better reflected by CMAP, probably due to it integrating both motor unit loss and reinnervation. The complementary nature of these profiles supports their combined use (concurrent application), and longitudinal studies are warranted to assess their responsiveness in adult SMA as well as their appropriateness for clinical trial settings.

Spinal muscular atrophy among US Hutterites: Phenotype variability in the setting of conserved ancestral haplotype and 4 SMN2 copies.

Genetics in medicine : official journal of the American College of Medical Genetics2026 Feb 12

Ideal timing and treatment in asymptomatic newborns with 4 SMN2 copies remains controversial. We examined phenotypic variability among the Hutterite population with spinal muscular atrophy (SMA) and higher SMN2 dosage. We enrolled individuals with SMA and children born to couples with 1 copy of SMN1 in South Dakota and Montana Hutterite communities in a natural history study that included a focused medical history and genomic screening for SMN1 deletion(s) and SMN2 copy number. Of the 215 Hutterite individuals enrolled, 75 carried at least 1 SMN1 deletion allele with >2 SMN2 copies. All 21 affected individuals (8 months to 41 years) had 0 SMN1 and 4 SMN2 copies but not the modifying variants SMN2 c.859G>C and SMN2 c.-44A>G. Clinical diagnoses of SMA type 3a (N = 14), SMA type 3b (N = 6), or SMA type 4 (N = 1) were determined based on age of onset and maximum achieved motor function. Although age of onset was highly variable (10 months to 25 years), most individuals presented in early childhood, indicating a need to identify biomarkers that can more accurately predict outcomes to help guide treatment intervention. This study also provides strong evidence supporting early implementation of therapies for patients with SMA with 4 copies of SMN2.

CSF and plasma GFAP and VEGF in adult type 3 spinal muscular atrophy patients treated with nusinersen.

Journal of the neurological sciences2026 Mar 15

Nusinersen improves motor outcomes in SMA, but reliable biomarkers for treatment monitoring, especially in adults, are still lacking. We investigated cerebrospinal fluid (CSF) and plasma levels of glial fibrillary acidic protein (GFAP) and vascular endothelial growth factor (VEGF), exploring their potential as biomarkers in disease progression. This single-centre observational study included adults with type 3 SMA treated with nusinersen over 30 months. GFAP and VEGF levels in CSF and plasma were measured using ELISA at baseline, 14 and 30 months. Functional evaluation included Hammersmith Functional Motor Scale Expanded (HFMSE), Revised Upper Limb Module (RULM), and respiratory tests. Longitudinal data were evaluated using generalized linear mixed-effects models. A significance level of α = 0.05 was used in all analyses. Eleven patients were included (63.6% male, aged 19-60 at baseline). Improvements were observed in motor function, with an estimated non-linear increase of 9.02% (CI95%: 5.13-8.79) for RULM and an estimated average increase of 6.96 points (CI95%: 5.44-8.48) for HFMSE over 30 months of treatment. However, both CSF and plasma GFAP and VEGF levels changes at 14 and 30 months did not reach statistical significance, respectively (all p > 0.05). CSF and plasma GFAP and VEGF trajectories over a 30-month period under nusinersen treatment were nonsignificant. This study confirms sustained motor function improvements in adult type 3 SMA patients treated with nusinersen. Future research in larger, multicentric, and internationally collaborative cohorts are essential to fully understand the role of these potential biomarkers in SMA pathogenesis.
