Who was studied 46,768 European ancestry low tanning cases, 74,528 European ancestry moderate and high tanning controls; replicated in 15,547 European ancestry low tanning cases, 39,835 European moderate and high tanning ancestry controls.
The effect
Each copy of the T allele shifted the measure 0.106 higher (95% confidence interval 0.02-0.192); p = 4 × 10−9.
Where it sits Chromosome 12, band 12q21.33 — between genes, 14 kb from LOC105369885.
What each result means
C/CNo copy of the version the research linked to Low tan response. This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to Low tan response. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Low tan response. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs2639099
What is rs2639099?
rs2639099 is a single position in the genome, in or near the near KITLG 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.
What conditions is rs2639099 linked to?
On MyGeneLog this position is linked to Sun Sensitivity, Freckling and Skin Cancer Risk. The research behind each link, and its sources, are set out on that condition page.
Does having rs2639099 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 rs2639099 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.
