Omega-3 fatty acids to total fatty acids percentage

FADS1 · rs75938339

What the study found

Who was studied 239,268 European ancestry individuals.

The effect The reported allele is C; the catalogue records no effect size ; p = 1 × 10−70.

Where it sits Chromosome 11, band 11q12.2 — in an intron of FADS1.

What each result means

C/C Two copies of the version the research linked to Omega-3 fatty acids to total fatty acids percentage. 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 Omega-3 fatty acids to total fatty acids percentage. That is a smaller link than two copies.
T/T No copy of the version the research linked to Omega-3 fatty acids to total fatty acids percentage. This is the starting point the study compared everyone against.

Questions about rs75938339

What is rs75938339?

rs75938339 is a single position in the genome, in or near the FADS1 gene. Published research associates it with omega-3 fatty acids to total fatty acids percentage. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs75938339 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 rs75938339 come from?

GWAS Catalog, HGG advances 2025, PMID:40545721. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
