Do genetic tests find new risk factors for Alzheimer's in veteran populations?
Genetic tests can identify new risk factors for Alzheimer's disease in veteran populations. A large meta-analysis that included data from the VA Million Veterans Program (MVP) discovered several new genetic locations (loci) linked to Alzheimer's risk in veterans of European, African, and Hispanic ancestry 4. This research expands our understanding of the genetic factors that contribute to Alzheimer's, especially in diverse groups like veterans.
What the research says
A major meta-analysis combined genetic data from the VA Million Veterans Program with other large studies to find new risk factors for Alzheimer's disease 4. In veterans of European ancestry, the study identified 17 new genetic loci beyond the well-known APOE region 4. It also found 4 new loci in African ancestry veterans and 3 in Hispanic ancestry veterans 4. These findings show that genetic tests can uncover risk factors specific to different populations, including veterans. Other large genetic studies have also identified new risk loci for late-onset Alzheimer's, such as IQCK, ACE, ADAM10, ADAMTS1, and WWOX 9. These discoveries help researchers understand the biological pathways involved in Alzheimer's, including immunity, lipid metabolism, and amyloid processing 9. Validating these genetic risk factors in animal models has shown that they can affect brain gene expression in ways that mimic human Alzheimer's 10. This suggests that the genetic risk factors found in veteran populations are biologically meaningful and could lead to new treatments.
What to ask your doctor
- Should I consider genetic testing for Alzheimer's risk, given my veteran status?
- What do the new genetic risk factors found in veteran populations mean for my personal risk?
- Are there any ongoing studies or clinical trials for veterans that use genetic testing for Alzheimer's?
- How might my genetic results affect my family members' risk or their own testing decisions?
- Can genetic testing help guide prevention or treatment strategies for Alzheimer's in veterans?
