What the study found

Who was studied 16,711 European ancestry cases, 118,152 European ancestry controls.

The effect Each copy of the A allele carried 1.07 times the odds of Shingles (95% confidence interval 1.06-1.09); p = 2 × 10−8.

How common The A allele had a frequency of about 56% in the people studied.

Where it sits Chromosome 9, band 9p21.3 — between genes, 0.8 kb from IFNA21.

What each result means

A/A Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Shingles compared to the general population.
A/G Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Shingles.
G/G Published research associates this genotype with typical/baseline likelihood of Shingles — no copies of the reported risk allele.

Questions about rs7047299

What is rs7047299?

rs7047299 is a single position in the genome, in or near the IFNA21 gene. Published research associates it with shingles. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs7047299 linked to?

On MyGeneLog this position is linked to Tonsillectomy (Throat Infection Susceptibility), Shingles. The research behind each link, and its sources, are set out on that condition page.

Does having rs7047299 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 rs7047299 come from?

GWAS Catalog, Nat Commun 2017, PMID:28928442. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
