What the study found

Who was studied 47,745 European ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.282 lower (95% confidence interval 0.2-0.37); p = 2 × 10−11.

How common The A allele had a frequency of about 0% in the people studied.

Where it sits Chromosome 2, band 2p12 — between genes, 13.1 kb from REG1B.

What each result means

A/A Two copies of the version the research linked to REG1A protein levels. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/G One copy of the version the research linked to REG1A protein levels. That is a smaller link than two copies.
G/G No copy of the version the research linked to REG1A protein levels. This is the starting point the study compared everyone against.

Questions about rs189958205

What is rs189958205?

rs189958205 is a single position in the genome, in or near the near REG1B gene. Published research associates it with reg1a 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 rs189958205 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 rs189958205 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 rs189958205 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.
