About SickleGenAfrica


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.

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.

She is currently working on studies involving intervention for individuals with Sickle Cell Disease such as early detection and management of complications, undergoing Hydroxyurea therapy. Her study will lead to an MSc by Research and Publication.

Dr. Najibah Galadanci

Site Coordinator - Kano

Najibah is an investigator and the site coordinator for the Kano, Nigeria site on the SickleGenAfrica: Sickle Cell Disease Genomics Network of Africa, where she oversees research activities, ensure protocol adherence, provide guidance for general clinic management of the study participants and also serve as a member of the steering and executive committee.

The H3Africa Consortium

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.
