What the study found

Who was studied 47,745 European ancestry individuals.

The effect Each copy of the C allele shifted the measure 0.0641 lower (95% confidence interval 0.05-0.078); p = 8 × 10−23.

How common The C allele had a frequency of about 19% in the people studied.

Where it sits Chromosome 10, band 10q24.1 — a missense change in PIK3AP1.

What ClinVar records

Classification Benign for Infantile spasms; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 2 submitters), last evaluated 2026-02-03. ClinVar record 1169953 NM_152309.3(PIK3AP1):c.1913A>G (p.Lys638Arg)

What this is ClinVar's aggregate record for this position (as of its 2026-10-19 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.

What each result means

C/C Two copies of the version the research linked to TCL1A protein levels. That is the strongest link of the three results. A link in a study is not a diagnosis.
C/T One copy of the version the research linked to TCL1A protein levels. That is a smaller link than two copies.
T/T No copy of the version the research linked to TCL1A protein levels. This is the starting point the study compared everyone against.

Questions about rs12784975

What is rs12784975?

rs12784975 is a single position in the genome, in or near the PIK3AP1 gene. Published research associates it with tcl1a protein levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs12784975 linked to?

On MyGeneLog this position is linked to Celiac Disease. The research behind each link, and its sources, are set out on that condition page.

Does having rs12784975 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 rs12784975 come from?

GWAS Catalog, Nature genetics 2025, PMID:39789286. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
