GRN · rs5848
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 1,963 European ancestry individuals, 848 Sorbian (founder/genetic isolate) individuals; replicated in 1800 European ancestry individuals.
The effect Each copy of the T allele shifted the measure 0.0665 lower (95% confidence interval -); p = 5 × 10−14.
How common The T allele had a frequency of about 25% in the people studied.
Where it sits Chromosome 17, band 17q21.31 — in the 3′ untranslated region of GRN.

What this is ClinVar's aggregate record for this position (as of its 2026-10-12 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.
rs5848 is a single position in the genome, in or near the GRN gene. Published research associates it with progranulin levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
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.
