Africa-Press – Namibia. <\/strong><\/span>It was just a \u201ccrazy idea\u201d to start with, says Ambroise Wonkam, professor of medical genetics at Cape Town university in South Africa. He is talking about his vision of creating a huge library of genetic information about the population of Africa, outlined in the science journal Nature, earlier this year.<\/p>\n

The Three Million African Genomes (3MAG) project emerged from his work on how genetic mutations among Africans contribute to conditions like sickle-cell disease and hearing impairments.<\/p>\n

He points out that African genes hold a wealth of genetic variation, beyond that observed by scientists in Europe and elsewhere. \u201cWe are all African but only a small fraction of Africans moved out of Africa about 20-40,000 years ago and settled in Europe and in Asia,\u201d he says.<\/p>\n

Prof Wonkam is also concerned about equity. \u201cToo little of the knowledge and applications from genomics have benefited the global south because of inequalities in health-care systems, a small local research workforce and lack of funding,\u201d he says.<\/p>\n

Only about 2% of the genomes mapped globally are African, and a good proportion of these are African American. This comes from a lack of prioritising funding, policies and training infrastructure, he says, but it also means the understanding of genetic medicine as a whole is lopsided.<\/p>\n

Studies of African genomes will also help to correct injustices, he says: \u201cEstimates of genetic risk scores for people of African descent that predict, say, the likelihood of cardiomyopathies or schizophrenia can be unreliable or even misleading using tools that work well in Europeans.\u201d<\/p>\n

To address these inequities, Prof Wonkam and other scientists are talking to governments, companies and professional bodies across Africa and internationally, in order to build up capacity over the next decade to make the vision a reality.<\/p>\n

The number of three million is the minimum he expects to accurately map genetic variations across Africa. As a comparison, the UK Biobank currently aims to sequence half a million genomes in under three years, but the UK\u2019s 68 million population is just a fraction of Africa\u2019s 1.3 billion.<\/p>\n

Prof Wonkam says the project will take 10 years, and will cost around $450m (\u00a3335m) per year, and says industry is already showing an interest in it. Biotech firms say they welcome any expansion of the library of African genomes.<\/p>\n

The Centre for Proteomic and Genomic Research (CPGR) in Cape Town works with biotech firm Artisan Biomed on a variety of diagnostic tests. The firm says it is affected by the gaps in the availability of genomic information relevant to local populations.<\/p>\n

For example, it may find a genetic mutation in someone and not know for certain if that variation is associated with a disease, especially as a marker for that particular population.<\/p>\n

\u201cThe more information you have at that level, the better the diagnosis, treatment and eventually care can be for any individual, regardless of your ethnicity,\u201d says Dr Lindsay Petersen, chief operations officer.<\/p>\n

Artisan Biomed says the data it collects feeds back into CPGR\u2019s research \u2013 allowing them to design a better diagnostic toolkit that is better suited to African populations, for instance.<\/p>\n

\u201cBecause of the limited data sets of the African genome, it needs that hand in hand connection with research and innovation, because without that it\u2019s just another test that has been designed for a Caucasian population that may or may not have much of an effect within the African populations,\u201d says Dr Judith Hornby Cuff.<\/p>\n

She says the 3MAG project would help streamline processes and improve the development of research, and perhaps one day provide cheaper, more effective and more accessible health care, particularly in the strained South African system.<\/p>\n

One of those hoping to take part in the 3MAG project is Dr Aron Abera, genomics scientist at Inqaba Biotech in Pretoria, which offers genetic sequencing and other services to research and industry.<\/p>\n

The firm employs over 100 people in South Africa, Ghana, Kenya, Mali, Nigeria Senegal, Tanzania, Uganda and Zimbabwe. Currently, most of the genetics samples collected in these countries are still processed in South Africa, but Dr Abera hopes to increase the number of laboratories soon.<\/p>\n

The gaps are not only in infrastructure, but also in staff. Over the last 20 years, Inqaba has focused on using staff and interns from the African continent \u2013 but it now has to expand its training programme as well.<\/p>\n

Back in Cape Town, Prof Wonkam says that while the costs are huge, the project will \u201cimprove capacity in a whole range of biomedical disciplines that will equip Africa to tackle public-health challenges more equitably\u201d. He says: \u201cWe have to be ambitious when we are in Africa. You have so many challenges you cannot see small, you have to see big \u2013 and really big.\u201d<\/p>\n
