  • Sickle Cell Disease:  The establishment of a Sickle Africa Data Coordinating Centre (SADaCC) under the directorship of Professor Ambroise Wonkam will provide an international resource for data gathering and research into Sickle Cell Anaemia.


An outpatient diagnostic, management and counselling service is provided directly through adult genetic clinics, a prenatal counselling clinic and familial cancer clinics at Groote Schuur Hospital and paediatric genetic clinics at Red Cross War Memorial Children’s Hospital. This is augmented by participation in a large number of multidisciplinary clinics on both platforms.
