What is the PCSK9 gene?
PCSK9 binds LDL receptors and promotes their removal. Lower PCSK9 activity can leave more LDL receptors available, while higher effective activity can reduce LDL receptor availability.
How PCSK9 affects metabolism
PCSK9-linked variants are interpreted through LDL-C, ApoB, and LDL receptor regulation. The report treats this as lipid pathway context, not medication advice.
What happens when PCSK9 is altered
A PCSK9 signal does not diagnose lipid disease. It makes LDL particle markers worth checking if the broader lipid pathway is active.
Curated SNP evidence for PCSK9
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
PCSK9 currently has 2 curated SNPs, 2 claim-level scores, and 1 claims eligible for pathway scoring.

LDL cholesterol tendency
rs11591147 T is associated with lower LDL cholesterol tendency as a PCSK9 loss-of-function proxy.
PCSK9 rs11591147 T is staged as a lipid biomarker-lowering allele, not as a cardiovascular disease-risk estimate.

biomarker tendency · AG
PCSK9-linked LDL cholesterol tendency
rs562556 AG carries one PCSK9 rs562556 G allele and is associated with lower LDL cholesterol tendency.
PCSK9 rs562556 AG is staged as a heterozygous LDL-C-lowering tendency signal.

Common symptoms people report
- family context around LDL cholesterol
- unexpected ApoB or LDL-C patterns
- lipid results that do not match diet or activity alone
Biomarkers to validate
ApoB
Shows atherogenic particle number more directly than total cholesterol.
LDL-C
Tracks the cholesterol carried in LDL particles.
Lipid panel
Provides HDL-C, triglycerides, and total cholesterol context.
Where DNA analysis helps
DNA helps decide whether LDL receptor regulation deserves attention inside the broader Lipids pathway.
Example interpretation
PCSK9 may add useful context when its SNP evidence lines up with the broader pathway signal.
Suggested validation: ApoB and LDL-C.
What to do next
- Check ApoB and LDL-C before interpreting the gene alone.
- Compare PCSK9 with LDLR, APOE, and lifestyle context.
- Use clinician guidance for medication questions.
