Inherited disorders in the Afrikaner population of southern Africa. Part I. Historical and demographic background, cardiovascular, neurological, metabolic and intestinal conditions

Abstract

Certain genetic disorders occur with unusually high frequency in the Afrikaner population of southern Africa. Conditions of this type (reviewed in Part I of this article) include familial hypercholesterolaemia, progressive familial heart block, Huntington's chorea, porphyria variegata, Gaucher's disease, cystic fibrosis and familial colonic polyposis. This genetic situation is explicable to some extent on the basis of the demographic development of the Afrikaner population during the 14 generations since the arrival of the first immigrants from Holland more than 330 years ago.
