Unravelling Alzheimer’s genetics in the Hispanic population
A study combining data from the Alzheimer’s Disease Sequencing Project and the All of Us biobank has identified two novel genetic loci associated with Alzheimer’s disease in individuals self-identifying as Hispanic. By using projected genetically-derived principal components to match heterogeneous cohorts, researchers overcame population stratification challenges. They discovered genome-wide significant associations for rare variants in the RGS6/PSEN1 and ASPSCR1 genes, which were also nominally significant in the All of Us sub-cohorts.
Why it might matter to you:
This work demonstrates a methodological advance for conducting genetic studies in underrepresented populations, a critical step for equitable biomarker discovery. For your focus on clinically actionable diagnostic assays, it underscores the importance of population-specific genetic architecture in interpreting proteomic signals and correlating them with other biomarkers. The identified genes could inform new pathways for blood-based biomarker development in Alzheimer’s disease.
