What the study found

Who was studied up to 449,889 European ancestry individuals, up to 29,398 South Asian ancestry individuals, up to 27,610 African American individuals, up to 8,839 East Asian individuals, up to 10,772 Hispanic ancestry individuals; replicated in up to 196,766 European ancestry individuals.

The effect Each copy of the C allele shifted the measure 0.0148 higher (95% confidence interval 0.011-0.019); p = 2 × 10−15.

How common The C allele had a frequency of about 63% in the people studied.

Where it sits Chromosome 15, band 15q24.1 — a missense change in BBS4.

What ClinVar records

Classification Benign for Bardet-Biedl syndrome, Bardet-Biedl syndrome 1, Bardet-Biedl syndrome 4, Early onset severe obesity; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 14 submitters), last evaluated 2026-02-04. ClinVar record 21734 NM_033028.5(BBS4):c.1061T>C (p.Ile354Thr)

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

Questions about rs2277598

What is rs2277598?

rs2277598 is a single position in the genome, in or near the BBS4 gene. Published research associates it with body mass index. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs2277598 linked to?

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

Does having rs2277598 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 rs2277598 come from?

GWAS Catalog, Nature genetics 2018, PMID:29273807. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
