Description
Genetic variation in PCSK9 has an enormous impact on LDL-C concentration in humans and both gain-of-function (GOF) and loss-of-function (LOF) PCSK9 mutations have been described. While PCSK9 LOF mutations cause hypocholesterolemia, GOF mutations are a rare cause of familial hypercholesterolemia (FH), a monogenic disease characterized by very high levels of LDL-C and premature atherosclerotic cardiovascular disease (ASCVD). PCSK9 GOF mutations are causative of FH, because the enhancement in PCSK9 function leads to increased LDLr degradation and reduced recycling to the cell surface. As a consequence, there is a reduction in LDL uptake and an increase in circulating LDL-C concentration. The best characterized PCSK9 GOF mutation is p.(Asp374Tyr) which produces a ten-fold increase in LDLr degradation by increasing the binding affinity of PCSK9 to the epidermal growth factor-like domain of LDLr. This variant was demonstrated to inhibit LDL uptake still at a concentration 25 times lower than the wild-type PCSK9.
