Deletion or mutation of SMN1 coupled with the inability of SMN2 to compensate for the loss of SMN1 due to exon 7 skipping causes spinal muscular atrophy (SMA), one of the leading genetic diseases of children.
<b>Aims:</b> To estimate healthcare resource utilization (HRU) and costs among patients with spinal muscular atrophy (SMA) type 1 (SMA1) in real-world practice, overall and among patients treated with nusinersen.

We developed a test procedure based on a cleanup protocol for dried blood spots and a quantitative (q)PCR to screen for a homozygous deletion of exon 7 of the survival of motor neuron 1 gene (SMN1) that is responsible for >95% of SMA patients.
In this review, we describe how structural elements formed by both local and long-distance interactions are being exploited to modulate SMN2 exon 7 splicing as a potential therapy for SMA.
This is an orthologue of the stasimon/tmem41b gene, a downstream target of SMN, the depleted protein in spinal muscular atrophy (SMA), which partially recapitulates the SMA phenotype in fly and zebrafish models when mutated.

We report here the finding of abnormal Golgi apparatus morphology in motor neuron like cells depleted of SMN as well as Golgi apparatus morphology in SMA patient fibroblasts.
The primary objective of the present study was to evaluate the applicability of the dosage of SMN gene produts in blood, as biomarker for SMA, and the safety of oral salbutamol, a beta2-adrenergic agonist modulating <i>SMN2</i> levels.
Primary hits were further evaluated for their ability to correct the splicing defect and resultant increase of SMN activity in SMA patient-derived fibroblasts.
This article summarizes the milestones in the development of onasemnogene abeparvovec leading to this first approval for the treatment of paediatric patients aged < 2 years with SMA and bi-allelic mutations in SMN1.
Spinal Muscular Atrophy type 1 (SMA1) is a rare genetic neuromuscular disease where 75% of SMA1 patients die/require permanent-ventilation by 13.6 months.
Lentiviral-mediated transgenic expression of SMN where the dilysine domain in exon 2b was mutated was not able to rescue the SMA phenotype despite robust expression of the mutant SMN protein in brain, muscle and spinal cord.
In two trials, oral administration of RG7800 increased in blood full-length SMN2 mRNA expression in healthy adults and SMN protein levels in SMA patients by up to two-fold, which is expected to provide clinical benefit.
<b>Background:</b> 5q spinal muscular atrophy (SMA) is an autosomal recessive lower motoneuron disease caused by deletion or mutations in the survival motor neuron 1 gene (<i>SMN1</i>) which results in reduced expression of full-length SMN protein.

Spinal muscular atrophy is a devastating neurodegenerative autosomal recessive disease that results from survival of motor neuron 1 (SMN1) gene mutation or deletion.
