Though we found that the following genes (ie EFTUD1/FAM154B at 15q25.2, RRN3P1, SLC16A5, and ANKHD1‐EIF4EBP3) were common association signals for AD and IS in terms of bioinformatics, less is known about their biological roles due to lack of overwhelming evidence related to AD or IS. Here, RRN3P1 is linked to Alzheimer disease.
