Who was studied 6,713 European ancestry cases, 48,402 European ancestry contols, 110 Southern Indian ancestry cases, 119 Southern Indian ancestry controls, 827 Japanese ancestry cases, 3,323 Japanese ancestry controls; replicated in 9,070 European ancestry cases, 7,683 European ancestry contols, 461 East Asian ancestry cases, 547 East Asian ancestry controls.
The effect
Each copy of the T allele carried 1.23 times the odds of Age-related macular degeneration (95% confidence interval 1.17-1.29); p = 4 × 10−13.
How common The T allele had a frequency of about 10% in the people studied.
Where it sits Chromosome 3, band 3q12.1 — in an intron of COL8A1.

ClinVar record 162163NM_020351.4(COL8A1):c.-4+17674G>T
What this is ClinVar's aggregate record for this position (as of its 2026-10-19 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.
What each result means
G/GNo copy of the version the research linked to Age-related macular degeneration. This is the starting point the study compared everyone against.
G/TOne copy of the version the research linked to Age-related macular degeneration. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Age-related macular degeneration. That is the strongest link of the three results. A link in a study is not a diagnosis.
Papers in Europe PMC whose title or abstract names both this rsID and that subject. A shared paper means somebody wrote about the two together — it is not a claim that this position explains the subject.
Questions about rs13081855
What is rs13081855?
rs13081855 is a single position in the genome, in or near the FILIP1L gene. Published research associates it with age-related macular degeneration. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs13081855 linked to?
On MyGeneLog this position is linked to Age-Related Macular Degeneration. The research behind each link, and its sources, are set out on that condition page.
What do people read about alongside rs13081855?
Subjects that appear in the title or abstract of the same papers as this rsID include allergies (1 papers). A shared paper means somebody wrote about the two together; it is not a claim that this position explains the topic.
Does having rs13081855 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 rs13081855 come from?
GWAS Catalog, Nat Genet 2013, PMID:23455636. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
