Spinal muscular atrophy (SMA) is a disease that robs people of physical strength by affecting the motor nerve cells in the spinal cord, taking away the ability to walk, eat, or breathe. It is the number one genetic cause of death for infants.

SMA is caused by a mutation in the survival motor neuron gene 1 (SMN1). In a healthy person, this gene produces a protein that is critical to the function of the nerves that control our muscles. Without it, those nerve cells cannot properly function and eventually die, leading to debilitating and sometimes fatal muscle weakness.

SMA affects approximately 1 in 11,000 births, and about 1 in every 50 Americans is a genetic carrier. SMA can affect any race or gender.

There are four primary types of SMA—1, 2, 3, and 4—based on the age that symptoms begin, and highest physical milestone achieved.

Individuals with SMA have difficulty performing the basic functions of life, like breathing and swallowing. However, SMA does not affect a person’s ability to think, learn, and build relationships with others.

More opportunities to learn about SMA below:

    • Identify strategies and/or methods to maintain respiratory health.
    • Discussion of strategies and/or methods to maintain motor function and mobility.
    • Recognize the therapeutic importance of maintaining optimal nutrition.
    • Communicate with individuals with SMA and their families about quality of life, challenges, and best practices in SMA.

Does your child show signs of a motor delay? Developmental delays can be early signs of a serious medical condition. Always trust your instincts. If something about your child’s development doesn’t feel quite right, don’t delay.

Early diagnosis is key… it’s a SMArt Move.
