Hemoglobin levels

CYP27A1 · rs13020432

What the study found

Who was studied 684,122 European ancestry individuals.

The effect Each copy of the C allele shifted the measure 0.016 higher; p = 1 × 10−13.

Where it sits Chromosome 2, band 2q35 — in an intron of CYP27A1.

What each result means

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

Questions about rs13020432

What is rs13020432?

rs13020432 is a single position in the genome, in or near the CYP27A1 gene. Published research associates it with hemoglobin levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs13020432 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 rs13020432 come from?

GWAS Catalog, Communications biology 2020, PMID:32327693. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
