Where this position leads

What the study found

Who was studied 228,926 European ancestry cases, 1,611,415 European ancestry controls.

The effect Each copy of the T allele shifted the measure 0.0274 lower (95% confidence interval 0.02-0.035); p = 3 × 10⁻¹².

How common The T allele had a frequency of about 74% in the people studied.

Where it sits Chromosome 18, band 18q12.1 — in an intron of DTNA.

What ClinVar records

Classification Benign; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 2 submitters), last evaluated 2018-06-15. ClinVar record 672653 NM_001386795.1(DTNA):c.1175+118T>C

What this is ClinVar's aggregate record for this position (as of its 2026-10-19 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.

What each result means

C/C No copy of the version the research linked to Atrial fibrillation. This is the starting point the study compared everyone against.

C/T One copy of the version the research linked to Atrial fibrillation. That is a smaller link than two copies.

T/T Two copies of the version the research linked to Atrial fibrillation. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs1790534

What is rs1790534?

rs1790534 is a single position in the genome, in or near the DTNA gene. Published research associates it with atrial fibrillation. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs1790534 linked to?

On MyGeneLog this position is linked to Atrial Fibrillation. The research behind each link, and its sources, are set out on that condition page.

Does having rs1790534 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 rs1790534 come from?

GWAS Catalog, Nature communications 2025, PMID:40645996. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
