Newly Discovered Protein Connected to Significant Increase in Risk of Alzheimer’s Disease

A new University of Southern California (USC) Leonard Davis School of Gerontology study found a significant increase in the risk for Alzheimer's disease is linked to a mutation in a minor protein that has recently been discovered. This opens up a new possible therapy route and broadens the list of known gene targets for the illness. The tiny "microprotein" with the name SHMOOSE is produced by a recently identified gene in the mitochondria of a cell. In four distinct cohorts, a mutation in this gene is associated with a 30% increased risk for Alzheimer's disease and partially inactivates the SHMOOSE microprotein. Nearly 25% of persons with European ancestry, according to the study, have the altered protein. The most common form of dementia is Alzheimer's. The disease is gradual, starting with mild memory loss and potentially progressing to the loss of communication and environmental awareness. The CDC estimates that 5.8 million Americans will have Alzheimer's d...
