Free thyroxine levels within normal range in pregnancy

SERPINA7 · rs2234036

What the study found

Who was studied 67,315 Chinese ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.246 higher (95% confidence interval 0.2-0.3); p = 4 × 10−22.

How common The T allele had a frequency of about 1% in the people studied.

Where it sits Chromosome X, band Xq22.3 — a missense change in SERPINA7.

What ClinVar records

Classification Conflicting classifications of pathogenicity for Thyroxine-binding globulin, variant A, Thyroxine-binding globulin deficiency, SERPINA7-related disorder; criteria provided, conflicting classifications (1 of 4 stars, 5 submitters), last evaluated 2025-03-01. ClinVar record 9784 NM_000354.5(SERPINA7):c.631G>A (p.Ala211Thr)

What this is ClinVar's aggregate record for this position (as of its 2026-10-12 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 Free thyroxine levels within normal range in pregnancy. This is the starting point the study compared everyone against.
C/T One copy of the version the research linked to Free thyroxine levels within normal range in pregnancy. That is a smaller link than two copies.
T/T Two copies of the version the research linked to Free thyroxine levels within normal range in pregnancy. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs2234036

What is rs2234036?

rs2234036 is a single position in the genome, in or near the SERPINA7 gene. Published research associates it with free thyroxine levels within normal range 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 rs2234036 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 rs2234036 come from?

GWAS Catalog, Nature communications 2024, PMID:39266554. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
