Who was studied up to 322 Han Chinese ancestry individuals with A blood group, up to 356 Han Chinese ancestry individuals with A blood group.
The effect
Each copy of the C allele carried 182.60 times the odds of ABO blood group (A vs O); p = 1 × 10−54.
How common The C allele had a frequency of about 32% in the people studied.
Where it sits Chromosome 9, band 9q34.2 — in an intron of ABO.
What each result means
C/CTwo copies of the version the research linked to ABO blood group (A vs O). That is the strongest link of the three results. A link in a study is not a diagnosis.
C/TOne copy of the version the research linked to ABO blood group (A vs O). That is a smaller link than two copies.
T/TNo copy of the version the research linked to ABO blood group (A vs O). This is the starting point the study compared everyone against.
rs9919007 is a single position in the genome, in or near the OBP2B gene. Published research associates it with abo blood group (a vs o). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs9919007 linked to?
On MyGeneLog this position is linked to ABO Blood Group. The research behind each link, and its sources, are set out on that condition page.
Does having rs9919007 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 rs9919007 come from?
GWAS Catalog, Genes 2021, PMID:34202464. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
