Asthma

HLA-B · rs114444221

Where this position leads

Condition: Asthma

Drugs: Abacavir, Allopurinol, Carbamazepine and oxcarbazepine

rs114444221 Condition: Asthma Asthma Condition Drug: Abacavir Abacavir Drug Drug: Allopurinol Allopurinol Drug Drug: Carbamazepine and oxcarbazepine Carbamazepine and oxcarbazepine Drug rs114444221 rs114444221 HLA-B

What the study found

Who was studied 40,544 European ancestry cases, 300,671 European ancestry controls.

The effect Each copy of the A allele carried 1.13 times the odds of Asthma (95% confidence interval 1.1-1.17); p = 9 × 10−16.

Where it sits Chromosome 6, band 6p21.33 — between genes, 18.3 kb from HLA-B.

What each result means

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

Questions about rs114444221

What is rs114444221?

rs114444221 is a single position in the genome, in or near the HLA-B gene. Published research associates it with asthma. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs114444221 linked to?

On MyGeneLog this position is linked to Asthma. The research behind each link, and its sources, are set out on that condition page.

Does rs114444221 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 rs114444221 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 rs114444221 come from?

GWAS Catalog, American journal of human genetics 2019, PMID:30929738. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
