The Claim
Nonsense mutations in the PCSK9 gene (Y142X and C679X) are associated with a 40% reduction in plasma LDL cholesterol levels in individuals of African descent, indicating that loss-of-function variants in PCSK9 can lead to significantly lower LDL cholesterol in this population.
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.
Some people of African descent have genetic changes in a gene called PCSK9 that seem to cut bad cholesterol levels by almost half—this might help explain why they have lower heart disease risk.
See the scientific wording
Nonsense mutations in the PCSK9 gene (Y142X and C679X) are associated with a 40% reduction in plasma LDL cholesterol levels in individuals of African descent, suggesting that loss-of-function variants in PCSK9 can lead to significantly lower LDL cholesterol in this population.
What the research says
1 studyThe study found that certain genetic changes (Y142X and C679X) in the PCSK9 gene cause much lower 'bad' cholesterol in people of African descent, just like the claim says.
