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 33,637 European ancestry individuals, 5,057 individuals.
The effect
The reported allele is T; the catalogue records no effect size
; p = 2 × 10−9.
How common The T allele had a frequency of about 83% in the people studied.
Where it sits Chromosome 3, band 3q27.3 — in an intron of MASP1.
What each result means
G/GNo copy of the version the research linked to Ascending thoracic aortic diameter. This is the starting point the study compared everyone against.
G/TOne copy of the version the research linked to Ascending thoracic aortic diameter. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Ascending thoracic aortic diameter. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs1108450
What is rs1108450?
rs1108450 is a single position in the genome, in or near the MASP1 gene. Published research associates it with ascending thoracic aortic diameter. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs1108450 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 rs1108450 come from?
GWAS Catalog, Nature genetics 2022, PMID:34837083. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
