SMA Gene Therapy | Overview

Boston Children’s Hospital is one of the first pediatric hospitals in the nation to offer an FDA-approved gene therapy for the treatment of spinal muscular atrophy (SMA). Known by the brand name Zolgensma®, formerly AVXS-101, this gene therapy prevents further motor neuron and muscle degeneration by replacing the defective or missing gene (SMN1) that causes SMA.

The SMN1 gene is responsible for making the survival motor neuron (SMN) protein. Just like its namesake, it is necessary for survival. Without a functional copy of SMN1, the motor neurons degenerate, leading to the signs and symptoms of SMA.


Who is eligible?

SMA gene therapy will be available for the treatment of children with SMA less than 2 years of age. This restriction is based on the population and dose approved by the FDA.
