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.

Strength of the evidence

2 / 4

Its strongest genetic-study result is p = 10⁻²⁸, 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 2,524 European ancestry individuals.

The effect Each copy of the G allele shifted the measure 0.175 lower (95% confidence interval 0.14-0.21); p = 6 × 10⁻²⁹.

How common The G allele had a frequency of about 27% in the people studied.

Where it sits Chromosome 13, band 13q31.3 — in an intron of GPC5.

What each result means

A/A No copy of the version the research linked to Cerebrospinal fluid protein GPC5 levels. This is the starting point the study compared everyone against.

A/G One copy of the version the research linked to Cerebrospinal fluid protein GPC5 levels. That is a smaller link than two copies.

G/G Two copies of the version the research linked to Cerebrospinal fluid protein GPC5 levels. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs345447

What is rs345447?

rs345447 is a single position in the genome, in or near the GPC5 gene. Published research associates it with cerebrospinal fluid protein gpc5 levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs345447 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 rs345447 come from?

GWAS Catalog, Science translational medicine 2026, PMID:42054495. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
