Who was studied 188,039 European ancestry individuals.
The effect
Each copy of the T allele shifted the measure 0.021 z score lower (95% confidence interval 0.015-0.027); p = 1 × 10−10.
How common The T allele had a frequency of about 40% in the people studied.
Where it sits Chromosome 3, band 3q24 — between genes, 8.8 kb from CPA3.
What each result means
C/CNo copy of the version the research linked to Birth weight. This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to Birth weight. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Birth weight. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs7647448
What is rs7647448?
rs7647448 is a single position in the genome, in or near the near CPA3 gene. Published research associates it with birth weight. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs7647448 linked to?
On MyGeneLog this position is linked to Birth Weight. The research behind each link, and its sources, are set out on that condition page.
Does having rs7647448 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 rs7647448 come from?
GWAS Catalog, The British journal of ophthalmology 2020, PMID:31097437. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
