PCSK9 inhibitors for treating familial hypercholesterolaemia

Familial hypercholesterolaemia is caused by mutations in genes that code for proteins involved in cholesterol metabolism. Patients heterozygous for mutations in LDLR respond to statin treatment, whereas individuals with homozygous LDLR mutations do not. PCSK9 inhibitors have been developed for treating familial hypercholesterolaemia, and results are promising for patients with either heterozygous or homozygous familial hypercholesterolaemia.
