Stands on its own.
Nothing else here links to this position yet — but the page above is the point: what the
research found, what each genotype means, and where it came from, in language you can
read. Links to conditions, drugs and the senses appear automatically if we write them.
What the study found
Who was studied 6,681 European ancestry female cases, 407,255 European ancestry female controls.
The effect
Each copy of the T allele carried 1.11 times the odds of Lichen sclerosus (95% confidence interval 1.07-1.15); p = 5 × 10−8.
How common The T allele had a frequency of about 67% in the people studied.
Where it sits Chromosome 5, band 5q33.3 — in an intron of MIR3142HG.
What each result means
G/GNo copy of the version the research linked to Lichen sclerosus. This is the starting point the study compared everyone against.
G/TOne copy of the version the research linked to Lichen sclerosus. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Lichen sclerosus. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs6887783
What is rs6887783?
rs6887783 is a single position in the genome, in or near the near PTTG1 gene. Published research associates it with lichen sclerosus. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs6887783 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 rs6887783 come from?
GWAS Catalog, The British journal of dermatology 2026, PMID:41850335. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
