Facing ethical concerns in the age of precise gene therapy: Outlook on inherited arrhythmias

World J Cardiol. 2024 Feb 26;16(2):64-66. doi: 10.4330/wjc.v16.i2.64.ABSTRACTThis editorial, comments on the article by Spartalis et al published in the recent issue of the World Journal of Cardiology. We here provide an outlook on potential ethical concerns related to the future application of gene therapy in the field of inherited arrhythmias. As monogenic diseases with no or few therapeutic options available through standard care, inherited arrhythmias are ideal candidates to gene therapy in their treatment. Patients with inherited arrhythmias typically have a poor quality of life, especially young people engaged in agonistic sports. While genome editing for treatment of inherited arrhythmias still has theoretical application, advances in CRISPR/Cas9 technology now allows the generation of knock-in animal models of the disease. However, clinical translation is somehow expected soon and this make consistent discussing about ethical concerns related to gene editing in inherited arrhythmias. Genomic off-target activity is a known technical issue, but its relationship with ethnical and individual genetical diversity raises concerns about an equitable accessibility. Meanwhile, the cost-effectiveness may further limit an equal distribution of gene therapies. The economic burden of gene therapies on healthcare systems is is increasingly recognized as a pressing concern. A growing body of studies are reporting uncertainty in payback periods with intuitive short-term effects for in...
