Spinal muscular atrophy (SMA) is a rare neuromuscular disorder characterized by loss of motor neurons and progressive muscle wasting, often leading to early death.

The disorder is caused by a genetic defect in the SMN1 gene, which encodes SMN, a protein widely expressed in all eukaryotic cells (that is, cells with nuclei, including human cells) and necessary for survival of motor neurons. Lower levels of the protein results in loss of function of neuronal cells in the anterior horn of the spinal cord and subsequent system-wide atrophy of skeletal muscles.

Spinal muscular atrophy
manifests in various degrees of severity, which all have in common progressive muscle wasting and mobility impairment. Proximal muscles, arm and leg muscles that are closer to the torso and respiratory muscles are affected first. Other body systems may be affected as well, particularly in early-onset forms of the disorder. SMA is the most common genetic cause of infant death.

Spinal muscular atrophy
is an inherited disorder and is passed on in an autosomal recessive manner. In December 2016, nusinersen(marketed as Spinraza) became the first approved drug to treat SMA while several other compounds remain in clinical trials.[1] 


Have you been told that your child will not achieve milestones due to their diagnosis? Would you like to explore possibilities rather than limitations? In this case study, Michelle Turner, Movement Expert, takes you through one of her Movement Lesson sessions. This is an almost 2 year old with Spinal Muscular Atrophy -SMA 1. This is before any treatment with spinraza.
