Gene swap may halt deadly childhood disorder

“We know that Parkinson’s disease, Alzheimer’s disease, cystic fibrosis, multiple sclerosis, and cancer all come from genes that are aberrantly spliced,” says lead researcher Ravindra Singh. “If this is a model disease, meaning we succeed in treating spinal muscular atrophy, we will know how to correct splicing of other genes in other diseases.” (Photo: Prominent green dots represent well-organized SMN bodies, or gems, in the nucleus of the treated cells.)
