Huntington's Chorea in South Africa
Abstract
A national investigation into the origin and frequency of Huntington's chorea in all population groups of South Africa has been carried out by Dr M.R. Hayden and colleagues of the Department of Human Genetics, University of Cape Town. A total of 481 persons, of whom 153 are still living, has been recorded. The disease is a lethal genetic neuro-psychiatric disorder characterised by chorea and dementia. Symptoms generally appear in adulthood and death usually occurs within 10 to 15 years of their appearance.
