Low cholesterol states: clinical implications and management.

In patients with severe monogenic hypocholesterolemia, early initiation of high-dose vitamin therapy and a low-fat diet are essential for optimal prognosis.

In particular, inhibitors of PCSK9 and ANGPTL3 show important clinical impact.
