Preliminary functional studies implicate these variants in the patient's disease.Genetic testing is regarded as the most reliable method for diagnosing CPVT, and accordingly, we advocate for the inclusion of TECRL gene screening in individuals who are clinically suspected of having CPVT, LQTS, or exercise-induced ventricular arrhythmias, as well as in cases of SCD of unknown etiology. The gene discussed is TECRL; the disease is Schnyder corneal dystrophy.
