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 9,664 Korean ancestry individuals.
The effect Each copy of the A allele shifted the measure 0.149 mg/dL lower; p = 3 × 10−150.
How common The A allele had a frequency of about 28% in the people studied.
Where it sits Chromosome 2, band 2q37.1 — in an intron of UGT1A4.
rs2221198 is a single position in the genome, in or near the UGT1A4 gene. Published research associates it with serum total bilirubin levels. 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.
