A children's hospital in Wisconsin said it accidentally disposed of the brain of a young woman that was donated for research. The woman had undergone pioneering gene treatments for a rare degenerative disease, and researchers hoped studying her brain would provide them with invaluable data.
Ashtyn Fellenz died at age 24 on December 5, 2024. As a child, she was diagnosed with Canavan Disease, a rare genetic disorder that causes the degeneration of the coating that protects nerves and a loss of white matter in the brain, according to Fox 6.
