How genes affect aging, behavior, and Alzheimer’s risk across diverse communities

Studying the Genetics of Aging, Behavioral, and Social Phenotypes in Diverse Populations

NIH-funded research University of Southern California · NIH-11323049

What this research studies

If you or a family member are worried about Alzheimer’s or aging, this project is making new genetic tools to include people from many racial and ethnic backgrounds. The team will create GRMMA, a method that helps combine mixed-ancestry genetic data without excluding non-European participants, and SBayes-Universal, a fast way to make polygenic risk scores by combining results across populations. They will test these tools on large human datasets like the UK Biobank and share the software and tutorials publicly. The goal is to make genetic findings about aging and Alzheimer’s more accurate and relevant for diverse communities.

Who could benefit from this research

Good fit: People from diverse racial and ethnic backgrounds who have genetic and health data in cohorts or biobanks, including individuals with aging-related conditions or Alzheimer’s, are the most relevant to this work.

Not a fit: People without genetic data or those seeking immediate clinical treatments are unlikely to gain direct, short-term medical benefit from this methods-focused project.

Why it matters

Potential benefit: If successful, these tools could make genetic research and future genetic risk predictions for aging and Alzheimer’s more accurate and applicable to people from underrepresented ancestries.

How similar studies have performed: Earlier multi-ancestry GWAS and polygenic score methods have improved inclusiveness but still leave biases and gaps, so this approach is a novel attempt to overcome known limitations.
