Wisconsin health care providers can nominate a condition to add to the Wisconsin newborn screening panel. The panel is part of the Wisconsin Newborn Screening program.
The purpose of this page is to show providers the nomination process for spinal muscular atrophy (SMA).
What is SMA
SMA is a neurodegenerative, autosomal, recessive genetic disease. It’s seen in about 1 in 10,000 births. It affects the motor neurons in the spinal cord and involves other organs. The cause of death in people with SMA is often respiratory failure.
There are five types of SMA based on how severe it is:
- Types 0 and I—Earliest onset and most severe.
- Type II—Presents by 18 months of age. The baby can often sit but can’t walk or stand.
- Type III—Presents between 18 months and 10 years of age. The child can often learn to stand and walk but loses those skills over time.
- Type IV—Mildest form and may not show symptoms until adulthood.
