As part of a multi-institutional study led by researchers from Boston University, we recently explored how genetic risk for Alzheimer’s disease may differ across subgroups within African American populations. Using genome-wide association data from both the VA Million Veteran Program and the Alzheimer’s Disease Genetics Consortium, we stratified analyses by sex, age at onset, and APOE-ε4 status—factors that are often biologically meaningful but underexamined in combination, particularly in non-European cohorts.

Figure 2. Forest plot showing the effect sizes (odds ratios) and 95% confidence intervals for the MVP/ADGC meta-analysis results for the genome-wide significant SNPs in both the stratum in which the association was identified and the opposite stratum. The green points show the effect of rs139130053 in APOE-ε4 negative individuals (upper green point) and APOE-ε4 positive individuals (lower green point). The pink points show the effect of rs115882880 in females (upper pink point) and males (lower pink point). The blue points show the effect of rs141838133 in individuals with onset age ≥ 75 years (upper blue point) and individuals with onset age < 75 years (lower blue point).
As recently reported in Alzheimer’s Research & Therapy, this approach uncovered three genome-wide significant loci outside of the APOE region: a variant near EPHA5 associated with earlier onset cases, a signal in GRIN3B (next to ABCA7) that was strongest in females, and a variant near TSPEAR in APOE-ε4 non-carriers. These genes are implicated in pathways related to synaptic plasticity, insulin signaling, and protein degradation—mechanisms that are increasingly recognized as relevant to Alzheimer’s disease pathophysiology.
These findings add to growing evidence that stratified genetic analysis—particularly in underrepresented populations—can reveal novel risk loci that may be missed in more generalized approaches. They underscore the importance of both diverse population representation and biologically informed subgroup analysis in dementia genetics. Together, these strategies offer a more nuanced view of Alzheimer’s disease risk and help illuminate the complexity of its genetic basis across different groups.
