We also investigated 22 variants associated with parents’ survival in three previous GWAS (Pilling et al., 2016) (Wright et al., 2019) (RHJ Timmers et al., 2019: of note, rs429358 (APOE e4)—related to both cardiovascular and Alzheimer's diseases—was not associated with the FI (p = 0.29) and the 9p21.3 variant rs2891168 in the lncRNA ANRIL—also known as CDKN2B‐AS1—showed evidence of association, although did not reach genome‐wide significance (p = 2*10−4). This evidence concerns the gene CDKN2B and early-onset autosomal dominant Alzheimer disease.
