Nearly 2% of births in sub-Saharan Africa are affected with sickle cell disease (SCD). Bacteria-related deaths in SCD have reduced dramatically in children in the last 30 years in the West, and it is anticipated that a similar drop will occur in Africa once prevention and prompt management of infections becomes widely implemented on the continent. During this same period, the death rate among adolescents and adults with SCD has not improved largely because we cannot predict, prevent and effectively manage the end-stage organ damage typical of this disease. The SickleGenAfrica Network is made up of African scientists and international collaborators who are going to study 7,000 children and adults with SCD in Africa to identify genetic markers associated with the development of organ damage, with a special emphasis on the body’s defence against molecules released from damaged red blood cells that cause tissue injury. The long-term goal of the network is to develop strategies to predict, prevent and treat organ damage in SCD.
To align the survival of individuals who have sickle cell disease in Africa with national norms.
To develop prognostic biomarkers of organ damage through the discovery of key genetic modifying factors and cognate mechanisms, and build capacity and career pipelines in Africa to support patient-centred research to advance the development of innovative therapy for SCD.
PROFESSOR SOLOMON OFORI-ACQUAH
Professor Solomon Ofori-Acquah is also Dean of the School of Biomedical and Allied Health Sciences, University of Ghana
Professor Ofori-Acquah was appointed Dean of the School of Biomedical and Allied Health Sciences in the University of Ghana in January 2017, and as Associate Professor of Medicine and Human Genetics, and Director of the Center for Translational and International Hematology in the University of Pittsburgh in 2013. He was born in Cape Coast, attended Adisadel College, and migrated to England in 1985 after “A” levels. He graduated from the Bromley College of Technology in 1989 with a Higher National Certificate in Medical Laboratory Sciences and a Fellowship (Part 1) in Laboratory Hematology in 1990. He graduated from Birkbeck College, University of London with an MSc in Bio-molecular Organization in 1992, and from King’s College School of Medicine and Dentistry, University of London in 2000 with a PhD in Molecular Genetics. Throughout his graduate studies he worked full-time as a Hematology Biomedical Scientist, at Farnborough hospital in Kent, and later at King’s College Hospital in London. After his PhD training he moved from the UK to the US to maintain his research interest in sickle cell disease. He was appointed Assistant Professor of Cell Biology and Neuroscience in 2002 at the University of South Alabama, and later joined Emory University, Atlanta, USA as Assistant Professor of Pediatrics in 2007 until his relocation to the University of Pittsburgh in 2013.
Professor Ofori-Acquah’s research interests are in the molecular pathogenesis, genetics and innovative therapy of acute complications of sickle cell disease with a focus on the lungs. He developed the first mouse model of the acute chest syndrome that helped to define extracellular heme as a prototypical erythroid danger associated molecular pattern molecule. His work on acute chest syndrome published in the prestigious Journal of Clinical Investigations in 2013 established him as one of the leading Sickle Cell Disease Research Scientist in the world; this year he will deliver the Symposium Keynote Address at the Annual Sickle Cell Disease Research and Education Symposium in the US. Currently, Pro. Ofori-Acquah maintains two active research programmes; one in the US focused primarily on preclinical studies using mouse models, and a second in Ghana focused on the influence of genetic variation on the risk and severity of major complications of sickle cell disease in two large patient cohorts in Accra and in Kumasi. The genetics work in Ghana is supported by the $5.5 million NIH grant with collaborative sites in Nigeria, South Africa, Tanzania and the US.
Professor Ofori-Acquah has received numerous research, training and achievement awards and honors. The NIH has continuously funded his work since 2004 with multiple R01 and R25 grants, and U01 and U54 awards totaling millions of US dollars. He has authored over 60 research papers, reviews and book chapters, and mentored over thirty students at undergraduate, graduate, postgraduate levels as well as many early stage investigators. He is a member of the review panels of several research grant agencies including the NIH, Wellcome Trust, American Society of Hematology, American Heart Association, and the UK Lottery. He serves on the advisory boards of many government and non-government entities, including the National Technical Advisory Committee for Newborn Screening for Ghana in 2011-2013.

Her study will lead to an MSc by Research and Publication.
Currently, there is an ongoing global effort to apply genomic science and associated technologies to further the understanding of health and disease in different populations, and, in particular, to identify individuals and populations who are at risk, due to genetic and/or environmental factors, for developing a specific disease. Possible outcomes of such research include early and more accurate diagnosis, the development of new drugs and potentially, personalized medicine - the systematic use of information about each individual patient to select or optimize the patient's preventative and therapeutic care.
However, most African countries are being left behind in this genomic revolution and if this is not urgently addressed, genomics will contribute to the widening of global and ethnic inequalities in health and economic well-being.
In response to this challenge, the African Society of Human Genetics, the National Institutes of Health (NIH) and the Wellcome Trust (WT) convened a Frontiers Meeting in Yaoundé, Cameroon in March 2009 to discuss a research agenda to study genetic diversity in health and disease in African populations. The meeting brought together scientific experts from a number of different fields to identify the major scientific questions, as well as the ethical and practical issues of pursuing a large-scale genomics research program in Africa. The key aim of the meeting was to engage with African scientists and other stakeholders in order to outline research priorities and discuss the appropriate study design needed to inform and ultimately impact health in the African populations. Following this meeting the concept of H3Africa was developed and the initiative was announced in June 2010. H3Africa is supported by the NIH Director's Common Fund as an initiative within its Global Health Program and by the Wellcome Trust as part of their continuing research portfolio in Africa.
