SLC41A1 · rs708727
Where this position leads
Conditions: Blood Cell Counts, Monocyte Count
Strength of the evidence
Its strongest genetic-study result is p = 10−10, with 4 associations in the GWAS Catalog.
4: ClinVar disease-causing, reviewed by an expert panel or a guideline (3–4 stars). 3: ClinVar, several labs agreeing (2 stars), or a genetic study at p ≤ 10−50. 2: ClinVar from one lab (1 star), or p ≤ 10−20. 1: ClinVar submitted without criteria (0 stars), or genome-wide significance (p ≤ 5×10−8). The higher of the two counts. It says how solid the evidence is, not whether it matters for a particular person.
What the study found
Who was studied 170,721 European ancestry individuals.
The effect Each copy of the A allele shifted the measure 0.0233 higher (95% confidence interval 0.016-0.03); p = 1 × 10−10.
How common The A allele had a frequency of about 42% in the people studied.
Where it sits Chromosome 1, band 1q32.1 — a synonymous change in SLC41A1.

Change history MyGeneLog™ keeps a copy of every weekly release from 2026-10-19 and compares them. This position's classification has not changed since.
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.

rs708727 is a single position in the genome, in or near the SLC41A1 gene. Published research associates it with monocyte count. 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, Monocyte Count. 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.
