Hippocampus iron levels (R2* MRI)

SFRP4 · rs1802074

What the study found

Who was studied 39,533 European ancestry individuals.

The effect Each copy of the C allele shifted the measure 0.0513 lower (95% confidence interval 0.034-0.068); p = 3 × 10−9.

Where it sits Chromosome 7, band 7p14.1 — a missense change in SFRP4.

What ClinVar records

Classification Benign for Pyle metaphyseal dysplasia, SFRP4-related disorder; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 3 submitters), last evaluated 2026-02-04. ClinVar record 1332946 NM_003014.4(SFRP4):c.1019G>A (p.Arg340Lys)

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 Two copies of the version the research linked to Hippocampus iron levels (R2* MRI). That is the strongest link of the three results. A link in a study is not a diagnosis.
C/T One copy of the version the research linked to Hippocampus iron levels (R2* MRI). That is a smaller link than two copies.
T/T No copy of the version the research linked to Hippocampus iron levels (R2* MRI). This is the starting point the study compared everyone against.

Questions about rs1802074

What is rs1802074?

rs1802074 is a single position in the genome, in or near the SFRP4 gene. Published research associates it with hippocampus iron levels (r2* mri). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs1802074 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 rs1802074 come from?

GWAS Catalog, Neurobiology of disease 2024, PMID:38789058. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
