Platelet count during first trimester of pregnancy

ITPR3 · rs751331

Strength of the evidence

2 / 4

Its strongest genetic-study result is p = 10−20, with 2 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 72,816 Chinese ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.182 higher (95% confidence interval 0.14-0.22); p = 1 × 10−20.

How common The A allele had a frequency of about 3% in the people studied.

Where it sits Chromosome 6, band 6p21.31 — in an intron of ITPR3.

What each result means

A/A Two copies of the version the research linked to Platelet count during first trimester of pregnancy. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/G One copy of the version the research linked to Platelet count during first trimester of pregnancy. That is a smaller link than two copies.
G/G No copy of the version the research linked to Platelet count during first trimester of pregnancy. This is the starting point the study compared everyone against.

Questions about rs751331

What is rs751331?

rs751331 is a single position in the genome, in or near the ITPR3 gene. Published research associates it with platelet count during first trimester of pregnancy. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs751331 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 rs751331 come from?

GWAS Catalog, Blood 2024, PMID:38064665. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
