Who was studied 15,056 European ancestry cases, 18,618 European ancestry proxy cases, 449,056 European ancestry controls; replicated in 22,632 European ancestry cases, 968,735 European ancestry controls.
The effect
Each copy of the A allele shifted the measure 0.389 higher (95% confidence interval 0.31-0.47); p = 8 × 10−22.
How common The A allele had a frequency of about 2% in the people studied.
Where it sits Chromosome 1, band 1q22 — between genes, 6.2 kb from SEMA4A.
What each result means
A/ATwo copies of the version the research linked to Parkinson's disease or first degree relation to individual with Parkinson's disease. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/GOne copy of the version the research linked to Parkinson's disease or first degree relation to individual with Parkinson's disease. That is a smaller link than two copies.
G/GNo copy of the version the research linked to Parkinson's disease or first degree relation to individual with Parkinson's disease. This is the starting point the study compared everyone against.
rs35643925 is a single position in the genome, in or near the SEMA4A gene. Published research associates it with parkinson's disease or first degree relation to individual with parkinson's disease. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs35643925 linked to?
On MyGeneLog this position is linked to Parkinson's Disease. The research behind each link, and its sources, are set out on that condition page.
Does having rs35643925 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 rs35643925 come from?
GWAS Catalog, Lancet Neurol 2019, PMID:31701892. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
