African genomes are not a subset.

Africa contains more genetic variation than the rest of the world combined, yet only about 1% of genomes in major databases are from individuals of African ancestry.

• Why it matters: This underrepresentation is a scientific error that hampers the accuracy of drug dosing, risk assessment, and the development of precision medicine worldwide.
• What they did: The study highlights the discrepancy between the genetic diversity in Africa and its minimal presence in genomic databases, emphasizing the need for more inclusive data collection.
• The result: Addressing this gap could improve the validity of genetic research and clinical applications globally, ensuring equitable and precise healthcare for populations of African ancestry.
