High density lipoprotein cholesterol levels

CHLSN · rs34409228

Strength of the evidence

2 / 4

Its strongest genetic-study result is p = 10−24, with 4 associations in the GWAS Catalog.

How this is scored

4: ClinVar disease-causing, reviewed by an expert panel or a guideline (3–4 stars). 3: ClinVar, several labs agreeing (2 stars), or a genetic study at p ≤ 10−50. 2: ClinVar from one lab (1 star), or p ≤ 10−20. 1: ClinVar submitted without criteria (0 stars), or genome-wide significance (p ≤ 5×10−8). The higher of the two counts. It says how solid the evidence is, not whether it matters for a particular person.

What the study found

Who was studied 1,320,016 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.0283 higher (95% confidence interval 0.024-0.032); p = 1 × 10−24.

How common The T allele had a frequency of about 13% in the people studied.

What each result means

C/C No copy of the version the research linked to High density lipoprotein cholesterol levels. This is the starting point the study compared everyone against.
C/T One copy of the version the research linked to High density lipoprotein cholesterol levels. That is a smaller link than two copies.
T/T Two copies of the version the research linked to High density lipoprotein cholesterol levels. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs34409228

What is rs34409228?

rs34409228 is a single position in the genome, in or near the CHLSN gene. Published research associates it with high density lipoprotein cholesterol levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs34409228 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 rs34409228 come from?

GWAS Catalog, Nature 2021, PMID:34887591. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
