Omega-3 fatty acid levels

TMEM101 · rs228787

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 = 8 × 10−15.

Where it sits Chromosome 17, band 17q21.31 — inside TMEM101.

What each result means

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

Questions about rs228787

What is rs228787?

rs228787 is a single position in the genome, in or near the TMEM101 gene. Published research associates it with omega-3 fatty acid levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs228787 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 rs228787 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.
