The Claim

In Black adults, the presence of a nonsense mutation in the PCSK9 gene is associated with a 28 percent reduction in mean LDL cholesterol levels and an 88 percent lower incidence of coronary heart disease over a 15-year period, with a hazard ratio of 0.11, indicating that genetically driven lifelong lowering of LDL cholesterol is strongly correlated with reduced cardiovascular risk, even in high-risk populations.

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.

In plain English

Black adults with a certain genetic mutation have much lower bad cholesterol and are way less likely to get heart disease over 15 years — this shows that keeping cholesterol low from an early age could really protect your heart, even if you're at higher risk.

In Black adults, carrying a nonsense mutation in the PCSK9 gene is associated with a 28 percent reduction in mean LDL cholesterol levels and an 88 percent lower incidence of coronary heart disease over 15 years, with a hazard ratio of 0.11, suggesting that genetically driven lifelong LDL lowering strongly correlates with reduced cardiovascular risk even in high-risk populations.

  1. Study: Sequence variations in PCSK9, low LDL, and protection against coronary heart disease.

    The study found that Black adults with a specific genetic change in the PCSK9 gene had much lower bad cholesterol and far fewer heart problems over 15 years, just like the claim says.
