Where this position leads

Condition: Cardiac Conduction Intervals (PR Interval and QRS Duration)

What the study found

Who was studied 39,717 European ancestry individuals, 690 Orcadian individuals; replicated in 7,170 European ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.49 ms higher (95% confidence interval 0.31-0.67); p = 3 × 10⁻⁸.

How common The A allele had a frequency of about 25% in the people studied.

Where it sits Chromosome 10, band 10q21.1 — in an intron of LNCAROD.

What each result means

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

A/G One copy of the version the research linked to QRS duration. That is a smaller link than two copies.

G/G No copy of the version the research linked to QRS duration. This is the starting point the study compared everyone against.

Questions about rs1733724

What is rs1733724?

rs1733724 is a single position in the genome, in or near the DKK1 gene. Published research associates it with qrs duration. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs1733724 linked to?

On MyGeneLog this position is linked to Cardiac Conduction Intervals (PR Interval and QRS Duration). The research behind each link, and its sources, are set out on that condition page.

Does having rs1733724 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 rs1733724 come from?

GWAS Catalog, Nat Genet 2010, PMID:21076409. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
