Spinal Muscular Atrophy and the Genes Involved


Spinal muscular atrophy (SMA) is a genetic disease that affects mostly children. Sadly, some forms of SMA can lead to death. The severe neuromuscular disease causes the inability to participate in daily life functions like walking, eating, or even breathing.

Read more about spinal muscular atrophy here.

This disease is caused by a mutation in the survival motor neuron gene 1 (SMN1). In a healthy person, the gene produces a protein that is crucial to the function of nerves that control our muscles. If the protein is not being produced as it should, nerve cells will not function properly and eventually die.

In this video shared by DNA Learning Center in 2012,  Dr. Charlotte Sumner explains how SMA is related to changes in the SMN1 and SMN2 genes and what the mutation of those genes mean to the development of SMA.

Find out more on how gene therapy can be used to treat SMA.
