Genotypic Prevention

Contrarily, genotypic prevention refers to actions taken to prevent the passing on of certain genotypes to the next generation, such as selective termination after prenatal diagnosis. Genotypic prevention is either carried out on behalf of a future parent (or two) as a method of lowering the likelihood of pregnancy, or it is carried out as a public health measure to lower the prevalence of a disease in the general populace. When germline gene editing is considered as an intervention on the gametes of potential parents prior to conception, the preventative objective of this technology becomes even more evident. Instead than focusing on a specific patient's display of pathological symptoms, the aim is to prevent the "vertical transmission" of harmful genes within families.
