Genome Editing and Inherited Cardiac Arrhythmias

Area of Science:

• Cardiovascular Genetics
• Molecular Biology
• Gene Editing Technologies

Background:

• Inherited arrhythmic disorders cause life-threatening arrhythmias and sudden cardiac death.
• Diagnosis is challenging due to genetic heterogeneity and incomplete penetrance.
• Current treatments are often invasive and only preventive.

Purpose of the Study:

• To explore the potential of genome editing, specifically CRISPR/Cas9, as a curative approach for inherited arrhythmic disorders.
• To evaluate the utility of genome editing in creating in vitro models for studying these conditions.

Main Methods:

• Utilizing CRISPR/Cas9 technology to target and correct genetic arrhythmogenic substrates.
• Developing in vitro models of cardiac arrhythmias using genome editing.
• Reviewing the current state of in vivo genome editing approaches.

Main Results:

• Genome editing successfully reproduced cardiac arrhythmias in vitro.
• In vitro models facilitate variant pathogenicity, mechanistic, and drug-testing studies.
• In vivo genome editing for these disorders remains under investigation regarding safety and efficacy.

Conclusions:

• CRISPR/Cas9-based genome editing holds significant potential for curing inherited arrhythmic disorders.
• In vitro applications are established for research, but in vivo strategies need further development.
• Future research should focus on the safety, specificity, and efficiency of in vivo genome editing methods.
