Who was studied 15,106 European ancestry cases, 1,405,552 European ancestry controls.
The effect
Each copy of the A allele shifted the measure 0.501 higher (95% confidence interval 0.33-0.67); p = 1 × 10−8.
How common The A allele had a frequency of about 1% in the people studied.
Where it sits Chromosome 16, band 16q12.1 — a missense change in ADCY7.
What each result means
A/APublished research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Lymphocytic thyroiditis compared to the general population.
A/CPublished research associates this genotype (one copy of the reported risk allele) with an intermediate association with Lymphocytic thyroiditis.
C/CPublished research associates this genotype with typical/baseline likelihood of Lymphocytic thyroiditis — no copies of the reported risk allele.

Questions about rs78534766
What is rs78534766?
rs78534766 is a single position in the genome, in or near the ADCY7 gene. Published research associates it with lymphocytic thyroiditis. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs78534766 linked to?
On MyGeneLog this position is linked to Lymphocytic Thyroiditis (Hashimoto's). The research behind each link, and its sources, are set out on that condition page.
Does having rs78534766 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 rs78534766 come from?
GWAS Catalog, Nature genetics 2026, PMID:41644669. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
