Who was studied 2,935 Qatari ancestry individuals.
The effect
Each copy of the G allele shifted the measure 0.369 higher (95% confidence interval 0.31-0.43); p = 1 × 10−33.
How common The G allele had a frequency of about 30% in the people studied.
Where it sits Chromosome 6, band 6p21.33 — in an intron of HLA-B.
What each result means
C/CNo copy of the version the research linked to MHC class I polypeptide-related sequence A levels. This is the starting point the study compared everyone against.
C/GOne copy of the version the research linked to MHC class I polypeptide-related sequence A levels. That is a smaller link than two copies.
G/GTwo copies of the version the research linked to MHC class I polypeptide-related sequence A levels. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs13213324
What is rs13213324?
rs13213324 is a single position in the genome, in or near the HLA-B gene. Published research associates it with mhc class i polypeptide-related sequence a levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does rs13213324 affect how medicines work?
HLA-B carries pharmacogenomic findings for Abacavir, Allopurinol, Carbamazepine and oxcarbazepine. That is educational information, not a prescription or a dosing guide. Any decision to start, stop or change a medicine belongs with the clinician or pharmacist managing your treatment.
Does having rs13213324 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 rs13213324 come from?
GWAS Catalog, Human molecular genetics 2023, PMID:36168886. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
