What each result means
C/C
Published research associates this genotype with typical/baseline likelihood of Low tan response — no copies of the reported risk allele.
C/T
Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Low tan response.
T/T
Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Low tan response compared to the general population.

Questions about rs17123518
What is rs17123518?
rs17123518 is a single position in the genome, in or near the C20orf203 gene. Published research associates it with low tan response. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs17123518 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 rs17123518 come from?
GWAS Catalog, Nat Commun 2018, PMID:29739929. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
