Where this position leads

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

What the study found

Who was studied 252,730 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 0.0218 lower (95% confidence interval 0.015-0.029); p = 6 × 10⁻¹⁰.

How common The A allele had a frequency of about 24% in the people studied.

Where it sits Chromosome 2, band 2q35 — at a splice region of OBSL1.

What ClinVar records

Classification Benign for 3M syndrome 2; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 9 submitters), last evaluated 2026-05-08. ClinVar record 334503 NM_015311.3(OBSL1):c.2682C>T (p.Asp894=)

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 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 rs3183099

What is rs3183099?

rs3183099 is a single position in the genome, in or near the OBSL1 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 rs3183099 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 rs3183099 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 rs3183099 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.
