Hippocampal subfield left CA1 volume (body)

PTCH1 · rs2274692

Strength of the evidence

1 / 4

Its strongest genetic-study result is p = 10−8, with 1 associations in the GWAS Catalog.

How this is scored

4: ClinVar disease-causing, reviewed by an expert panel or a guideline (3–4 stars). 3: ClinVar, several labs agreeing (2 stars), or a genetic study at p ≤ 10−50. 2: ClinVar from one lab (1 star), or p ≤ 10−20. 1: ClinVar submitted without criteria (0 stars), or genome-wide significance (p ≤ 5×10−8). The higher of the two counts. It says how solid the evidence is, not whether it matters for a particular person.

What the study found

Who was studied 38,977 European ancestry, East Asian ancestry individuals.

The effect Each copy of the G allele shifted the measure 0.0447 lower (95% confidence interval 0.03-0.059); p = 4 × 10−9.

How common The G allele had a frequency of about 37% in the people studied.

Change history MyGeneLog™ keeps a copy of every weekly release from 2026-10-19 and compares them. This position's classification has not changed since.

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 No copy of the version the research linked to Hippocampal subfield left CA1 volume (body). This is the starting point the study compared everyone against.
C/G One copy of the version the research linked to Hippocampal subfield left CA1 volume (body). That is a smaller link than two copies.
G/G Two copies of the version the research linked to Hippocampal subfield left CA1 volume (body). That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs2274692

What is rs2274692?

rs2274692 is a single position in the genome, in or near the PTCH1 gene. Published research associates it with hippocampal subfield left ca1 volume (body). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs2274692 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 rs2274692 come from?

GWAS Catalog, Nature genetics 2023, PMID:37337106. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
