Spinal Muscular Atrophy: Signs, Causes, and Treatment Explained

2 minute read

By Laura Thomas

Spinal muscular atrophy (SMA) is a debilitating genetic disease that affects the central nervous system, specifically the motor neurons that control muscle movement. This progressive condition leads to muscle weakness and atrophy.

Understanding Spinal Muscular Atrophy

Spinal muscular atrophy is a genetic disorder caused by mutations in the SMN1 gene, which is responsible for producing the survival motor neuron (SMN) protein. This essential protein plays a crucial role in the function and survival of motor neurons. When the SMN protein is deficient or absent, motor neurons degenerate, leading to progressive muscle weakness and atrophy. SMA primarily affects infants and young children, with varying degrees of severity based on the type of mutation and the amount of SMN protein produced.1

Exploring Causes and Treatment Options

The field of SMA research has witnessed remarkable progress in recent years, leading to the development of innovative treatment options. One groundbreaking approach is gene therapy, which aims to address the root cause of SMA by introducing a functional copy of the SMN1 gene into the body.2 This revolutionary therapy has shown promising results in clinical trials, offering hope for individuals with SMA.

Additionally, antisense oligonucleotides (ASOs) have emerged as another promising treatment option. These synthetic molecules target and modify the splicing of SMN2, a related gene that can partially compensate for the loss of SMN1. By increasing the production of functional SMN protein, ASOs can help improve muscle function and slow the progression of SMA.

Recognizing Early Signs and Symptoms

Early detection and intervention are crucial in managing SMA effectively. Recognizing the early signs and symptoms of this condition is essential for prompt diagnosis and timely treatment. Some common indicators of SMA include:

If you or a loved one is experiencing any of these symptoms, it is crucial to seek medical attention promptly for an accurate diagnosis and appropriate treatment.
