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 27,900 European ancestry females.
The effect
Each copy of the C allele shifted the measure 5.86 z score lower; p = 5 × 10−9.
How common The C allele had a frequency of about 45% in the people studied.
Where it sits Chromosome 11, band 11p15.5 — in an intron of LSP1.
What each result means
C/CTwo copies of the version the research linked to Percent mammographic density. That is the strongest link of the three results. A link in a study is not a diagnosis.
C/TOne copy of the version the research linked to Percent mammographic density. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Percent mammographic density. This is the starting point the study compared everyone against.
Breast cancer research : BCR · 2022 · PMID 35414113 · open access
Questions about rs4980383
What is rs4980383?
rs4980383 is a single position in the genome, in or near the LSP1 gene. Published research associates it with percent mammographic density. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs4980383 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 rs4980383 come from?
GWAS Catalog, Breast cancer research : BCR 2022, PMID:35414113. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
