A/APublished research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Narcolepsy (age of onset) compared to the general population.
A/GPublished research associates this genotype (one copy of the reported risk allele) with an intermediate association with Narcolepsy (age of onset).
G/GPublished research associates this genotype with typical/baseline likelihood of Narcolepsy (age of onset) — no copies of the reported risk allele.

Questions about rs7744020
What is rs7744020?
rs7744020 is a single position in the genome, in or near the HLA-DQA1 gene. Published research associates it with narcolepsy (age of onset). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs7744020 linked to?
On MyGeneLog this position is linked to Narcolepsy. The research behind each link, and its sources, are set out on that condition page.
Does having rs7744020 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 rs7744020 come from?
GWAS Catalog, PLoS Genet 2013, PMID:24204295. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
