Spinal muscular atrophy Type 1 is a severe neuromuscular disorder that typically manifests in infancy. It is characterized by rapid muscle weakness, difficulties with swallowing, and respiratory complications, which can be life-threatening. SMA Type 1 is caused by a genetic mutation that affects the survival of motor neurons, leading to progressive muscle wasting.

Jesy Nelson has become a vocal advocate for newborn screening of SMA Type 1.

Early diagnosis is crucial for timely intervention and treatment, which can significantly improve outcomes for affected infants.

Jesy’s campaign aims to raise public awareness and influence policy changes to ensure that babies born with SMA Type 1 receive prompt diagnosis and care. Her personal experience with Story and Ocean has fueled her determination to support other families facing similar challenges.
