HDL cholesterol levels

HCAR1 · rs838777

What the study found

Who was studied 403,943 European ancestry individuals.

The effect Each copy of the C allele shifted the measure 0.0183 lower (95% confidence interval 0.013-0.024); p = 4 × 10−11.

How common The C allele had a frequency of about 86% in the people studied.

Where it sits Chromosome 12, band 12q24.31 — between genes, 26.6 kb from HCAR2.

What each result means

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

Questions about rs838777

What is rs838777?

rs838777 is a single position in the genome, in or near the HCAR1 gene. Published research associates it with hdl 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 rs838777 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 rs838777 come from?

GWAS Catalog, PLoS medicine 2020, PMID:32203549. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
