Alzheimer's Gene Found to Affect Women Over Men
from the San Francisco Chronicle
A gene that's been known for two decades as the largest inheritable risk for developing Alzheimer's disease mostly affects the brains of women, not men, according to a team of researchers from Stanford and UCSF.
The gene variant known as APOE4 is the most common genetic risk factor for Alzheimer's - only about 15 percent of people carry the gene, but it's found in more than half of all Alzheimer's patients.
The variant was first connected to Alzheimer's in 1993, but doctors and scientists for the most part have been unaware of any gender differences, despite early studies that showed an increased risk for women with the gene.
