HDL cholesterol levels

MC4R · rs1942880

What the study found

Who was studied 34,930 East Asian ancestry individuals, 187,167 European ancestry individuals; replicated in 8,741 Chinese ancestry individuals.

The effect The reported allele is T; the catalogue records no effect size ; p = 1 × 10−8.

How common The T allele had a frequency of about 34% in the people studied.

Where it sits Chromosome 18, band 18q21.32 — in an intron of LINC03111.

What each result means

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

Questions about rs1942880

What is rs1942880?

rs1942880 is a single position in the genome, in or near the MC4R 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 rs1942880 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 rs1942880 come from?

GWAS Catalog, Human molecular genetics 2017, PMID:28334899. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
