What the study found

Who was studied 507,850 East Asian ancestry individuals, 420,829 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.0194 lower (95% confidence interval 0.017-0.022); p = 2 × 10−72.

Where it sits Chromosome 19, band 19q13.2 — a synonymous change in B3GNT8.

What ClinVar records

Classification Benign for Familial cancer of breast; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 3 submitters), last evaluated 2018-07-05. ClinVar record 1248115 NM_001385648.2(B3GNT8):c.564G>A (p.Val188=)

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

C/C No copy of the version the research linked to Height. This is the starting point the study compared everyone against.
C/T One copy of the version the research linked to Height. That is a smaller link than two copies.
T/T Two copies of the version the research linked to Height. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs284661

What is rs284661?

rs284661 is a single position in the genome, in or near the B3GNT8 gene. Published research associates it with height. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs284661 linked to?

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

Does having rs284661 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 rs284661 come from?

GWAS Catalog, Nature communications 2025, PMID:40436827. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
