CYP3A4 · rs34642455
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 790 Hispanic, European, Asian, South Asian or African American individuals.
The effect Each copy of the C allele shifted the measure 2.17 lower (95% confidence interval 1.43-2.91); p = 3 × 10−8.
How common The C allele had a frequency of about 13% in the people studied.
Where it sits Chromosome 7, band 7q22.1 — in an intron of CYP3A4.
rs34642455 is a single position in the genome, in or near the CYP3A4 gene. Published research associates it with neonatal cytokine/chemokine levels (maternal genetic 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.
