Red blood cell volume distribution width variation in pregnancy

near SMG9 · rs346527

What the study found

Who was studied 98,021 Chinese ancestry individuals; replicated in 46,217 Chinese ancestry individuals.

The effect Each copy of the G allele shifted the measure 0.0575 lower (95% confidence interval 0.039-0.076); p = 7 × 10−10.

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

Where it sits Chromosome 19, band 19q13.31 — between genes, 0.2 kb from SMG9.

What each result means

A/A No copy of the version the research linked to Red blood cell volume distribution width variation in pregnancy. This is the starting point the study compared everyone against.
A/G One copy of the version the research linked to Red blood cell volume distribution width variation in pregnancy. That is a smaller link than two copies.
G/G Two copies of the version the research linked to Red blood cell volume distribution width variation in pregnancy. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs346527

What is rs346527?

rs346527 is a single position in the genome, in or near the near SMG9 gene. Published research associates it with red blood cell volume distribution width variation in pregnancy. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs346527 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 rs346527 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.
