What the study found

Who was studied 394,642 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.139 higher (95% confidence interval 0.097-0.181); p = 1 × 10−11.

How common The T allele had a frequency of about 0% in the people studied.

Where it sits Chromosome 7, band 7q22.1 — at a splice region of TFR2.

What ClinVar records

Classification Conflicting classifications of pathogenicity for Hemochromatosis type 3, Hereditary hemochromatosis; criteria provided, conflicting classifications (1 of 4 stars, 3 submitters), last evaluated 2026-01-28. ClinVar record 695306 NM_003227.4(TFR2):c.473+8T>A

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 No copy of the version the research linked to Red blood cell erythrocyte count (UKB data field 30010). This is the starting point the study compared everyone against.
A/T One copy of the version the research linked to Red blood cell erythrocyte count (UKB data field 30010). That is a smaller link than two copies.
T/T Two copies of the version the research linked to Red blood cell erythrocyte count (UKB data field 30010). That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs148902192

What is rs148902192?

rs148902192 is a single position in the genome, in or near the TFR2 gene. Published research associates it with red blood cell erythrocyte count (ukb data field 30010). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs148902192 linked to?

On MyGeneLog this position is linked to Celiac Disease. The research behind each link, and its sources, are set out on that condition page.

Does having rs148902192 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 rs148902192 come from?

GWAS Catalog, Nature genetics 2025, PMID:39789286. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
