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 35,657 White British ancestry individuals.

The effect The reported allele is C; the catalogue records no effect size ; p = 4 × 10⁻¹⁵.

How common The C allele had a frequency of about 48% in the people studied.

Where it sits Chromosome 1, band 1q32.2 — between genes, 38.7 kb from PLXNA2.

What each result means

C/C Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Cortical surface area compared to the general population.

C/T Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Cortical surface area.

T/T Published research associates this genotype with typical/baseline likelihood of Cortical surface area — no copies of the reported risk allele.

Questions about rs6681821

What is rs6681821?

rs6681821 is a single position in the genome, in or near the near PLXNA2 gene. Published research associates it with cortical surface area. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs6681821 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 rs6681821 come from?

GWAS Catalog, NeuroImage 2021, PMID:34560273. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
