Genetic risk of Alzheimer’s has gender bias

Carrying a copy of the “Alzheimer’s gene” doesn’t significantly raise a man’s risk of developing the disease.

The gene does increase a woman’s risk, but women with one copy of the gene were as likely to develop the disease as men with no copies. The study – along with work suggesting that the gene is associated with educational achievement in young people – highlights how much remains to be done to untangle the genetics of Alzheimer’s.
