Although genomics, the study of specific genes, has been increasingly recognized as central to research into ways to prolong and improve human life, the majority of studies continue to engage more Caucasian participants than any other race. A recent study of the resultant imbalance, conducted by renowned scientists at the MRC/UVRI and LSHTM Uganda Research Unit has highlighted several emerging challenges that, if unchecked, could potentially reverse the gains so far realized from decades of research.    

Dr. Segun Fatumo and Prof Karoline Kuchenbaecker in their 2022 study entitled A Roadmap to Increase Diversity in Genomic Studies speak of a global genomic revolution being slowed down by a decided lack of diversity in test subjects for research trials. They detail several missed opportunities for relevant scientific discoveries that have come as a result of the absence of varied samples during testing processes. With the only limited non-European genes being sourced from a few African subjects in the diaspora, the researchers cite a lack of depth and relevance to the resultant data. They say;

Studying a small number African diaspora populations (African American and Black participants in the United Kingdom and Europe) and grouping all participants into a broad category of African ancestry will continue to promote imbalance, widen health disparities, and will fail to capture the genetic diversity in Africa.

The study therefore recommends that advancements should be made in genomic technology, infrastructure and funding to ensure the effective inclusion of participants with multiple ancestries. This, according to the researchers will facilitate sustainable representation of Africans and Asians in genetic studies.

It further proposes that for even more equitable inclusion of underrepresented groups, all relevant stakeholders in the arena of science should prioritize the promotion of local participation, trust-building and mutual respect.
