The Future Emerges from the Past : Comment on "Personal Genomic Testing, Genetic Inheritance, and Uncertainty"

The case of Jordan (Mason 2017) highlights the gamble of connecting with the past through genomic testing. Unfortunately for Jordan, his genomic testing identified two variant genes which account for up to 75 per cent of early-onset Alzheimer's disease cases. Furthermore, his children were identified as having a 50 per cent risk of inheriting the gene which corresponds to the majority of early-onset Alzheimer's disease cases. Now Jordan is not only burdened with the foreknowledge that he will most likely develop Alzheimer's disease at a relatively young age but also burdened with the knowledge that his children may share his fate. Jordan was overwhelmed by his attempts to understand the genetic tests and experienced substantial distress. This response highlights the need for industry-wide regulations that adequately prepare individuals for the decision of whether to initiate genomic testing and require the results to be interpreted with genetic counsellors or other suitably skilled doctors. Furthermore, these industry-wide regulations need to be accountable to the same evidence-based standards that regulate the rest of the medical professions.
