The Claim
Loss-of-function mutations in the PCSK9 gene are associated with lifelong lower low-density lipoprotein (LDL) cholesterol levels and a significantly reduced risk of coronary heart disease.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People with certain genetic changes that turn down a protein called PCSK9 tend to have lower 'bad' cholesterol their whole lives and are much less likely to get heart disease.

What the research says
3 studiesStudy: Sequence variations in PCSK9, low LDL, and protection against coronary heart disease.
People with certain genetic changes in the PCSK9 gene have lower 'bad' cholesterol and much lower chances of heart disease, which is exactly what this study found.
The study looks at people with natural changes in the PCSK9 gene that lower bad cholesterol, and finds they have a much lower risk of heart disease — which supports the claim.
The study found that people with broken versions of the PCSK9 gene have much lower 'bad' cholesterol, which supports the idea that these gene changes protect against heart disease.
