African genomes are not a subset.

African genomes encompass over 1.4 billion individuals and contain more genetic variation than the rest of the world combined, yet only about 1% of genomes in major databases are of African ancestry.

• Why it matters: This underrepresentation hampers the accuracy of medical research and the development of personalized treatments, leading to health disparities and scientific inaccuracies in global medicine.
• What they did: The study highlights the vast genetic diversity in Africa and emphasizes that African genomes are not just a subset but a distinct and essential component of human genetic variation.
• The result: Addressing this disparity will improve drug dosing, risk assessment, and precision medicine worldwide, ensuring equitable and scientifically sound healthcare for all populations.
