APOEε4 confers less risk for Alzheimer disease (AD) in carriers with African local genomic ancestry (ALA) than APOEε4 carriers with European local ancestry (ELA). Cell type specific transcriptional variation between the two local ancestries (LAs) could contribute to this disease risk differences. Single-nucleus RNA sequencing was performed on frozen frontal cortex of homozygous APOEε4 AD patients: seven with ELA, four with ALA. 60,908 nuclei were sequenced. Within the LA region (chr19:44–46Mb), APOEε4 was the gene most differentially expressed, with ELA carriers having significantly more expression (overall p < 1.8E−317) in 24 of 32 cell clusters. The transcriptome of one astrocyte cluster, with high APOEε4 expression and specific to ELA, is suggestive of A1 reactive astrocytes. AD patients with ELA expressed significantly greater levels of APOE than ALA APOEε4 carriers. These differences in APOEε4 expression could contribute to the reduced risk for AD seen in African APOEε4 carriers.
