Abstract
INTRODUCTION
Multi-omics studies in Alzheimer’s disease (AD) revealed many potential disease pathways and therapeutic targets. Despite their promise of precision medicine, these studies lacked Black Americans (BA) and Latin Americans (LA), who are disproportionately affected by AD.
METHODS
To bridge this gap, Accelerating Medicines Partnership in Alzheimer’s Disease (AMP-AD) expanded brain multi-omics profiling to multi-ethnic donors.
RESULTS
We generated multi-omics data and curated and harmonized phenotypic data from BA (n = 306), LA (n = 326), or BA and LA (n = 4) brain donors plus non-Hispanic White (n = 252) and other (n = 20) ethnic groups, to establish a foundational dataset enriched for BA and LA participants. This study describes the data available to the research community, including transcriptome from three brain regions, whole genome sequence, and proteome measures.
DISCUSSION
The inclusion of traditionally underrepresented groups in multi-omics studies is essential to discovering the full spectrum of precision medicine targets that will be pertinent to all populations affected with AD.
Highlights
Accelerating Medicines Partnership in Alzheimer’s Disease Diversity Initiative led brain tissue profiling in multi-ethnic populations.
Brain multi-omics data is generated from Black American, Latin American, and non-Hispanic White donors.
RNA, whole genome sequencing and tandem mass tag proteomicsis completed and shared.
Multiple brain regions including caudate, temporal and dorsolateral prefrontal cortex were profiled.
