What the study found

Who was studied 60,343 European ancestry, African ancestry, Hispanic or Latin American, South East Asian ancestry, South Asian ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.0282 higher (95% confidence interval 0.02-0.037); p = 9 × 10−11.

How common The A allele had a frequency of about 14% in the people studied.

Where it sits Chromosome 18, band 18p11.31 — in an intron of MYL12-AS1.

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/T One copy of the version the research linked to QRS duration. That is a smaller link than two copies.
T/T No copy of the version the research linked to QRS duration. This is the starting point the study compared everyone against.

Questions about rs1662340

What is rs1662340?

rs1662340 is a single position in the genome, in or near the MYL12-AS1 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 rs1662340 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 rs1662340 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 rs1662340 come from?

GWAS Catalog, Nature communications 2022, PMID:36050321. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
