The Claim

The PCSK9 nonsense mutations Y142X and C679X occur at a combined frequency of 2% in African Americans and less than 0.1% in European Americans, demonstrating a significant ethnic difference in the prevalence of these loss-of-function genetic variants.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Two specific genetic changes that can affect heart health are much more common in African Americans than in white Americans.

The PCSK9 nonsense mutations Y142X and C679X occur at a combined frequency of 2% in African Americans but are rare in European Americans (less than 0.1%), indicating a significant ethnic difference in the prevalence of these loss-of-function genetic variants.

What the research says

1 study
  1. Study: Low LDL cholesterol in individuals of African descent resulting from frequent nonsense mutations in PCSK9

    The study found that two genetic changes in the PCSK9 gene are much more common in African Americans than in European Americans, which matches exactly what the claim says.
