The Claim
Loss-of-function mutations in the PCSK9 gene are associated with lifelong lower low-density lipoprotein (LDL) cholesterol levels and an 88% reduced risk of coronary artery disease, indicating that pharmacological inhibition of PCSK9 may confer cardiovascular protection by reducing LDL receptor degradation and increasing clearance of LDL cholesterol from the bloodstream.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People born with a certain gene change that breaks the PCSK9 gene tend to have much lower 'bad' cholesterol their whole lives and are far less likely to get heart disease — so scientists think blocking this gene with medicine might help protect others' hearts too.

What the research says
1 studyStudy: PCSK9 Inhibition: Insights From Clinical Trials and Future Prospects
The study looks at drugs that block a protein called PCSK9, which helps lower bad cholesterol and reduces heart disease risk, just like what happens in people with natural mutations in the PCSK9 gene. This supports the idea that blocking PCSK9 is protective for the heart.
