CYP26A1 · rs2149108

What the study found

Who was studied 67,040 British ancestry individuals; replicated in 28,509 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.01 lower; p = 4 × 10−10.

How common The T allele had a frequency of about 40% in the people studied.

Where it sits Chromosome 10, band 10q23.33 — between genes, 0.3 kb from NIP7P1.

What each result means

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

Questions about rs2149108

What is rs2149108?

rs2149108 is a single position in the genome, in or near the CYP26A1 gene. Published research associates it with optic disc size. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs2149108 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 rs2149108 come from?

GWAS Catalog, Human molecular genetics 2019, PMID:31809533. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
