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 764 European ancestry individuals, 48 South Asian ancestry individuals, 126 East Asian ancestry individuals, 26 African American or Afro-Caribbean individuals, 16 Other admixed ancestry and unknown ancestry individuals; replicated in 395 individuals.
The effect
Each copy of the T allele shifted the measure 6.03 zscore higher; p = 2 × 10−9.
Where it sits Chromosome 19, band 19q13.33 — in the 3′ untranslated region of FUT1.
What each result means
C/CNo copy of the version the research linked to Total concentration of 19 human milk oligosaccharides. This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to Total concentration of 19 human milk oligosaccharides. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Total concentration of 19 human milk oligosaccharides. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs4015
What is rs4015?
rs4015 is a single position in the genome, in or near the FUT1 gene. Published research associates it with total concentration of 19 human milk oligosaccharides. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs4015 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 rs4015 come from?
GWAS Catalog, Nature communications 2024, PMID:39232002. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
