The Claim
Common genetic variants in the APOE gene, particularly the ε4 allele tagged by the lead variant rs429358, are associated with reduced lifespan in individuals of European ancestry, with a highly significant association (p = 3.9 × 10−45), primarily due to increased mortality from circulatory and nervous system diseases such as cardiovascular disease and Alzheimer’s disease.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Having a certain version of a gene called APOE — especially the ε4 type — might mean people of European background don’t live as long, mainly because it raises the risk of heart problems and Alzheimer’s.

Common genetic variants in the APOE gene, particularly the ε4 allele, are associated with reduced lifespan in individuals of European ancestry, with the lead variant rs429358 showing a highly significant association (p = 3.9 × 10−45). This association is primarily driven by increased mortality from circulatory and nervous system diseases, including cardiovascular disease and Alzheimer’s disease.
What the research says
1 studyStudy: Rare genetic associations with human lifespan in UK Biobank are enriched for oncogenic genes
The study looked at genes affecting how long people live and found that the APOE gene, which the claim is about, really does affect lifespan, just like the claim says.
