What is the HJV gene?
Hemojuvelin BMP co-receptor supporting hepcidin signaling and iron-loading control.
How HJV affects metabolism
When HJV-related function is shifted, the practical effect is interpreted through hepcidin signaling, iron export, and whether iron tends to accumulate or run low. This does not mean the pathway is active or impaired right now; it means the gene can help prioritize what to check next.
What happens when HJV is altered
Altered HJV signal should be treated as a DNA-based tendency, not a diagnosis. 1 claim currently passes the report-use gate. The useful question is whether symptoms, labs, and lifestyle context line up with the pathway signal.
Curated SNP evidence for HJV
These SNPs come from the approved study-level evidence model. Each claim is scored from curated study rows, then gated before it can influence pathway scoring.
Evidence-backed report connection
HJV currently has 1 curated SNPs, 1 claim-level scores, and 1 claims eligible for pathway scoring.

HJV hepcidin signaling tendency
rs74315323 A, corresponding to HJV c.959G>T / p.Gly320Val in transcript orientation, is associated with lower HJV hepcidin signaling tendency in recessive or compound-heterozygous juvenile hemochromatosis contexts.
HJV rs74315323 A is staged as the forward-genomic recurrent recessive juvenile-hemochromatosis allele affecting hepcidin-upstream iron regulation.

Common symptoms people report
- fatigue or weakness that overlaps with iron status
- family or lab concern around ferritin or transferrin saturation
- iron markers outside the expected range
Biomarkers to validate
Ferritin
Shows stored iron, interpreted with inflammation context.
Transferrin saturation and serum iron
Checks circulating iron availability.
CBC and MCV
Adds red-blood-cell context.
Where DNA analysis helps
DNA helps decide whether HJV deserves attention inside the broader Iron handling pathway. It is most useful when combined with biomarkers instead of used as a standalone answer.
Example interpretation
HJV may add context to hepcidin signaling, iron export, and whether iron tends to accumulate or run low, especially when its SNP evidence lines up with other genes in the same pathway.
Suggested validation: Ferritin.
What to do next
- Review the Iron handling pathway result before interpreting HJV on its own.
- Use relevant biomarkers to confirm whether this DNA tendency is visible in current biology.
- Treat supplement or nutrition decisions as follow-up steps only after the pattern fits symptoms or labs.
