GLI3 · rs3801203
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 310 European ancestry Alzheimer's disease individuals, 511 European ancestry individuals with late mild cognitive impairment, 280 European ancestry individuals with early mild cognitive impairment, 94 European ancestry individuals with significant memory concern, 365 European ancestry individuals with normal cognition.
The effect Each copy of the A allele shifted the measure 0.261 lower (95% confidence interval 0.17-0.35); p = 3 × 10−9.
How common The A allele had a frequency of about 19% in the people studied.
Where it sits Chromosome 7, band 7p14.1 — in an intron of GLI3.

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.
rs3801203 is a single position in the genome, in or near the GLI3 gene. Published research associates it with language performance in older adults (adjusted for episodic memory). 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.
