The Claim
In individuals of European ancestry, rare loss-of-function variants in the TET2 gene are associated with a significantly reduced lifespan, with a hazard ratio of 2.3 for earlier mortality among carriers compared to non-carriers, based on analysis of 393,833 UK Biobank participants; this association remains robust across multiple statistical models and validation analyses, and the allele frequency distribution suggests a contribution from clonal hematopoiesis, a somatic process linked to blood cancers.
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.
If you're of European descent and carry a rare broken version of the TET2 gene, you might not live as long — studies suggest these people are more than twice as likely to die earlier than those without it, possibly because of a blood-related aging process linked to cancer.

The association is robust across multiple statistical models and validation analyses, and the variant allele frequency distribution suggests a contribution from clonal hematopoiesis, a somatic process linked to blood cancers.
What the research says
1 studyStudy: Rare genetic associations with human lifespan in UK Biobank are enriched for oncogenic genes
The study found that people with certain rare genetic changes in the TET2 gene tend to live shorter lives, which matches the main point of the claim.
