A key Alzheimer’s gene emerges in African American brain study

Scientists studying Alzheimer’s in African Americans have uncovered a striking genetic clue that may cut across racial lines. In brain tissue from more than 200 donors, the gene ADAMTS2 was significantly more active in people with Alzheimer’s than in those without it. Even more surprising, this same gene topped the list in an independent study of White individuals. The discovery hints at a common biological pathway behind Alzheimer’s and opens the door to new treatment strategies.
