What the study found

Who was studied 434,646 British ancestry individuals, 8,796 British Central/South Asian individuals, 6,573 British African individuals.

The effect Each copy of the G allele shifted the measure 0.02 % lower (95% confidence interval 0.02-0.02); p = 8 × 10−16.

Where it sits Chromosome 7, band 7q31.2 — in an intron of CFTR.

What each result means

A/A No copy of the version the research linked to Triglycerides to Total Lipids in Small HDL percentage. This is the starting point the study compared everyone against.
A/G One copy of the version the research linked to Triglycerides to Total Lipids in Small HDL percentage. That is a smaller link than two copies.
G/G Two copies of the version the research linked to Triglycerides to Total Lipids in Small HDL percentage. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs6977665

What is rs6977665?

rs6977665 is a single position in the genome, in or near the CFTR gene. Published research associates it with triglycerides to total lipids in small hdl percentage. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs6977665 linked to?

On MyGeneLog this position is linked to Cholesterol (LDL, HDL and Total). The research behind each link, and its sources, are set out on that condition page.

Does rs6977665 affect how medicines work?

CFTR carries pharmacogenomic findings for Elexacaftor/tezacaftor/ivacaftor (Trikafta), Ivacaftor, Vanzacaftor/tezacaftor/deutivacaftor (Alyftrek). That is educational information, not a prescription or a dosing guide. Any decision to start, stop or change a medicine belongs with the clinician or pharmacist managing your treatment.

Does having rs6977665 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 rs6977665 come from?

GWAS Catalog, Nature genetics 2025, PMID:41044249. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
