EEFSEC · rs2955117
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 43,568 European ancestry mothers; replicated in 8,643 European ancestry mothers.
The effect Each copy of the A allele shifted the measure 0.911 higher; p = 9 × 10−15.
How common The A allele had a frequency of about 29% in the people studied.
Where it sits Chromosome 3, band 3q21.3 — in an intron of EEFSEC.
rs2955117 is a single position in the genome, in or near the EEFSEC gene. Published research associates it with gestational age at birth (maternal effect). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
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.
