Therapeutic genome engineering: Implications for South Africa

Abstract

South Africa encompasses extraordinary genetic diversity, frequently revealing unique mutations and variations associated with disease. Despite the advances of traditional gene therapy, our understanding of causative mutations in the South African population has, for the most part, contributed to diagnostic rather than therapeutic interventions. Recent developments in genome engineering and its ease of use have released a powerful tool with which to intervene in otherwise untreatable disease. In addition, harnessing this tool for discrete genetic edits provides a mechanism by which screening of new drugs specific to our population’s diversity can be accomplished. Here, we use examples of some of the most advanced genome engineering approaches to develop therapeutic strategies that would specifically affect South African individuals.
