Maternal age at pregnancy

near SLC17A3 · rs7750960

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 109,941 Chinese ancestry individuals.

The effect Each copy of the C allele shifted the measure 0.0548 lower (95% confidence interval 0.036-0.073); p = 9 × 10−9.

How common The C allele had a frequency of about 5% in the people studied.

What each result means

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

Questions about rs7750960

What is rs7750960?

rs7750960 is a single position in the genome, in or near the near SLC17A3 gene. Published research associates it with maternal age at pregnancy. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs7750960 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 rs7750960 come from?

GWAS Catalog, Nature genetics 2026, PMID:42509370. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
