Who was studied 47,745 European ancestry individuals.
The effect
Each copy of the G allele shifted the measure 0.0829 lower (95% confidence interval 0.072-0.094); p = 2 × 10−53.
How common The G allele had a frequency of about 45% in the people studied.
Where it sits Chromosome 7, band 7q31.1 — in an intron of LAMB1.
What each result means
A/ANo copy of the version the research linked to LAMB1 protein levels. This is the starting point the study compared everyone against.
A/GOne copy of the version the research linked to LAMB1 protein levels. That is a smaller link than two copies.
G/GTwo copies of the version the research linked to LAMB1 protein levels. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs1544474
What is rs1544474?
rs1544474 is a single position in the genome, in or near the LAMB1 gene. Published research associates it with lamb1 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 rs1544474 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 rs1544474 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 rs1544474 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.
