Total bilirubin levels

SAG · rs137886124

What the study found

Who was studied 341,077 European ancestry individuals, 5,978 African ancestry individuals, 7,313 South Asian ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.169 lower (95% confidence interval 0.13-0.21); p = 3 × 10−16.

Where it sits Chromosome 2, band 2q37.1 — a missense change in SAG.

What ClinVar records

Classification Conflicting classifications of pathogenicity for Retinitis pigmentosa, Retinitis pigmentosa 47, Oguchi disease-1, Retinitis pigmentosa 96; criteria provided, conflicting classifications (1 of 4 stars, 5 submitters), last evaluated 2026-01-25. ClinVar record 720101 NM_000541.5(SAG):c.374C>T (p.Thr125Met)

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 Total bilirubin levels. This is the starting point the study compared everyone against.
C/T One copy of the version the research linked to Total bilirubin levels. That is a smaller link than two copies.
T/T Two copies of the version the research linked to Total bilirubin levels. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs137886124

What is rs137886124?

rs137886124 is a single position in the genome, in or near the SAG gene. Published research associates it with total bilirubin levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs137886124 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 rs137886124 come from?

GWAS Catalog, Nature genetics 2021, PMID:33462484. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
