What the study found

Who was studied 47,745 European ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.401 lower (95% confidence interval 0.34-0.46); p = 1 × 10−43.

How common The A allele had a frequency of about 1% in the people studied.

Where it sits Chromosome 5, band 5q13.2 — a missense change in NAIP.

What ClinVar records

Classification Likely benign; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 2 submitters), last evaluated 2018-06-08. ClinVar record 710844 NM_004536.3(NAIP):c.189G>T (p.Arg63Ser)

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 Two copies of the version the research linked to IL18 protein levels. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/C One copy of the version the research linked to IL18 protein levels. That is a smaller link than two copies.
C/C No copy of the version the research linked to IL18 protein levels. This is the starting point the study compared everyone against.

Questions about rs115486998

What is rs115486998?

rs115486998 is a single position in the genome, in or near the NAIP gene. Published research associates it with il18 protein levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs115486998 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 rs115486998 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 rs115486998 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.
