Where this position leads
Condition: Blood Cell Counts
What the study found
Who was studied 170,494 European ancestry individuals.
The effect Each copy of the C allele shifted the measure 0.0882 higher (95% confidence interval 0.064-0.112); p = 8 × 10−13.
How common The C allele had a frequency of about 2% in the people studied.
Where it sits Chromosome 15, band 15q15.1 — in the 5′ untranslated region of CAPN3.

What this is ClinVar's aggregate record for this position (as of its 2026-09-24 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.
rs149698681 is a single position in the genome, in or near the CAPN3 gene. Published research associates it with monocyte percentage of white cells. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
On MyGeneLog this position is linked to Blood Cell Counts. The research behind each link, and its sources, are set out on that condition page.
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.
