Cortical surface area

STX18-AS1 · rs6854227

What the study found

Who was studied 35,657 White British ancestry individuals.

The effect The reported allele is G; the catalogue records no effect size ; p = 6 × 10−11.

How common The G allele had a frequency of about 44% in the people studied.

Where it sits Chromosome 4, band 4p16.2 — in an intron of STX18-AS1.

What each result means

A/A No copy of the version the research linked to Cortical surface area. This is the starting point the study compared everyone against.
A/G One copy of the version the research linked to Cortical surface area. That is a smaller link than two copies.
G/G Two copies of the version the research linked to Cortical surface area. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs6854227

What is rs6854227?

rs6854227 is a single position in the genome, in or near the STX18-AS1 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 rs6854227 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 rs6854227 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.
