What the study found

Who was studied 153,950 Korean ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.0301 higher (95% confidence interval 0.022-0.038); p = 3 × 10−13.

How common The T allele had a frequency of about 31% in the people studied.

Where it sits Chromosome 19, band 19p13.11 — between genes, 2.2 kb from RAB8A.

What each result means

A/A No copy of the version the research linked to Mean corpuscular volume. This is the starting point the study compared everyone against.
A/T One copy of the version the research linked to Mean corpuscular volume. That is a smaller link than two copies.
T/T Two copies of the version the research linked to Mean corpuscular volume. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs28855197

What is rs28855197?

rs28855197 is a single position in the genome, in or near the near RAB8A gene. Published research associates it with mean corpuscular volume. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs28855197 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 rs28855197 come from?

GWAS Catalog, Nature communications 2025, PMID:40436827. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
