C/CNeither copy carries the associated allele. Near huntingtin — the gene whose CAG repeat expansion causes Huntington's disease. This is a separate, common variant nearby and has nothing to do with that diagnosis; what it is doing here is not established. On its own this tells one person almost nothing: the effect is a small shift in a population average, and how long anyone lives is mostly not genetic at all.
C/TOne copy of the associated allele. Evenly common worldwide, about 36-39% in every group measured. What was measured is a difference in average parental lifespan across half a million families — months, not years, and invisible in any one family.
T/TTwo copies. Still a shift in an average rather than a fact about a life. The reason to record it is what it points at biologically, not what it predicts.
This is an association with how long a population lives, not a prediction about one person. Nothing here is used clinically, nothing here is a reason to take anything, and no genotype at this position changes what anyone should do.

Questions about rs61348208
What is rs61348208?
rs61348208 is a single position in the genome, in or near the HTT gene. Published research associates it with parental lifespan (near htt). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs61348208 linked to?
On MyGeneLog this position is linked to Human Lifespan and Longevity. The research behind each link, and its sources, are set out on that condition page.
Does having rs61348208 mean I will get this?
No. Common variants like this one move a probability slightly and, on their own, rarely decide anything about one person. Nothing on this page is a diagnosis, and health decisions should be made with a clinician who can see your whole picture.
Where does the information about rs61348208 come from?
Timmers et al., Genomics of 1 million parent lifespans implicates novel pathways and common diseases and distinguishes survival chances, eLife 2019 (PMID 30642433); GWAS Catalog study GCST009890. Position and alleles checked against Ensembl (GRCh38). Reported P = 6e-9. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
