Who was studied up to 586,626 European ancestry individuals, up to 19,433 African ancestry individuals.
The effect
Each copy of the A allele shifted the measure 0.6 years higher (95% confidence interval -); p = 4 × 10−8.
How common The A allele had a frequency of about 9% in the people studied.
Where it sits Chromosome 6, band 6p21.32 — between genes, 5.2 kb from HLA-DQA1.
What each result means
A/APublished research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Parental lifespan compared to the general population.
A/CPublished research associates this genotype (one copy of the reported risk allele) with an intermediate association with Parental lifespan.
C/CPublished research associates this genotype with typical/baseline likelihood of Parental lifespan — no copies of the reported risk allele.

Questions about rs34831921
What is rs34831921?
rs34831921 is a single position in the genome, in or near the HLA-DQA1 gene. Published research associates it with parental lifespan. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs34831921 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 rs34831921 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 rs34831921 come from?
GWAS Catalog, Nat Commun 2017, PMID:29030599. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
