Familial hypercholesterolemia (FH) is a frequent genetic disorder (1/200) associated with an increased risk of early-onset myocardial infarction. To improve detection and treatment of patient with FH, cascade genetic testing in families is recommended by many cardiovascular prevention guidelines. However, the implementation of national genetic cascade screening is challenging, because legal protection to guarantee privacy of data do not authorize physicians to directly contact at-risk relatives. Using current mobile information technologies and a centralized web-based platform, we designed an ethical genetic cascade screening program for FH to be tested in Switzerland.
