Stands on its own.
Nothing else here links to this position yet — but the page above is the point: what the
research found, what each genotype means, and where it came from, in language you can
read. Links to conditions, drugs and the senses appear automatically if we write them.
What the study found
Who was studied 34,184 European ancestry cases, 305,742 European ancestry controls; replicated in 47,180 adults, 10,554 children or adolescents.
The effect
The reported allele is T; the catalogue records no effect size
; p = 5 × 10−12.
Where it sits Chromosome 11, band 11q23.3 — in an intron of MPZL3.
What each result means
C/CNo copy of the version the research linked to Sleep duration (long sleep). This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to Sleep duration (long sleep). That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Sleep duration (long sleep). That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs75458655
What is rs75458655?
rs75458655 is a single position in the genome, in or near the MPZL2 gene. Published research associates it with sleep duration (long sleep). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs75458655 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 rs75458655 come from?
GWAS Catalog, Nature communications 2019, PMID:30846698. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
