Serum uromodulin levels (antibody-based assay)

B4GALNT2 · rs7224888

What the study found

Who was studied 11,369 European ancestry individuals, 400 African American individuals, 2,216 Hispanic individuals.

The effect Each copy of the T allele shifted the measure 0.252 lower (95% confidence interval 0.21-0.29); p = 2 × 10−32.

How common The T allele had a frequency of about 90% in the people studied.

Where it sits Chromosome 17, band 17q21.32 — a missense change in B4GALNT2.

What ClinVar records

Classification Benign for BLOOD GROUP, SID SYSTEM; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 3 submitters), last evaluated 2020-02-17. ClinVar record 1286620 NM_001159387.2(B4GALNT2):c.1216T>C (p.Cys406Arg)

What this is ClinVar's aggregate record for this position (as of its 2026-10-12 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 Serum uromodulin levels (antibody-based assay). This is the starting point the study compared everyone against.
C/T One copy of the version the research linked to Serum uromodulin levels (antibody-based assay). That is a smaller link than two copies.
T/T Two copies of the version the research linked to Serum uromodulin levels (antibody-based assay). That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs7224888

What is rs7224888?

rs7224888 is a single position in the genome, in or near the B4GALNT2 gene. Published research associates it with serum uromodulin levels (antibody-based assay). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs7224888 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 rs7224888 come from?

GWAS Catalog, JCI insight 2022, PMID:35446786. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
