What the study found

Who was studied Up to 70,389 European ancestry individuals, up to 672 Orcadian individuals; replicated in Up to 33,316 European ancestry individuals.

The effect Each copy of the G allele shifted the measure 0.81 lower (95% confidence interval 0.61-1.01); p = 1 × 10−15.

How common The G allele had a frequency of about 35% in the people studied.

Where it sits Chromosome 1, band 1q24.2 — in an intron of SLC19A2.

What ClinVar records

Classification Benign; criteria provided, single submitter (1 of 4 stars, 1 submitter), last evaluated 2018-06-14. ClinVar record 683854 NM_006996.3(SLC19A2):c.807+210T>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

A/A No copy of the version the research linked to QT interval. This is the starting point the study compared everyone against.
A/G One copy of the version the research linked to QT interval. That is a smaller link than two copies.
G/G Two copies of the version the research linked to QT interval. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs1983546

What is rs1983546?

rs1983546 is a single position in the genome, in or near the ATP1B1 gene. Published research associates it with qt interval. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs1983546 linked to?

On MyGeneLog this position is linked to QT Interval and Drug-Induced Long QT. The research behind each link, and its sources, are set out on that condition page.

Does having rs1983546 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 rs1983546 come from?

GWAS Catalog, Nat Genet 2014, PMID:24952745. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
