FH and Hypercholesterolemia: When we looked more closely at the criteria for genetic testing of paediatric patients, we found that LDL-C plasma levels, as well as family history for hypercholesterolemia and premature coronary vascular disease, are considered by 74.3% of centres dealing with adult patients and 80% of those dealing with paediatric ones, and this is in line with the recommendations by most recent consensus documents on paediatric FH [19,23,24].
