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 247,107 European ancestry individuals; replicated in 63,326 European ancestry individuals, 33,171 South Asian ancestry individuals.
The effect
Each copy of the T allele shifted the measure 0.035 higher (95% confidence interval 0.03-0.04); p = 7 × 10−36.
How common The T allele had a frequency of about 69% in the people studied.
Where it sits Chromosome 1, band 1p32.3 — in an intron of FAF1.
What each result means
C/CNo copy of the version the research linked to Thyroid stimulating hormone levels. This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to Thyroid stimulating hormone levels. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Thyroid stimulating hormone levels. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs1398868
What is rs1398868?
rs1398868 is a single position in the genome, in or near the FAF1 gene. Published research associates it with thyroid stimulating hormone levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs1398868 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 rs1398868 come from?
GWAS Catalog, Nature communications 2023, PMID:37872160. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
