Outline of Final Research Achievements |
A gain-of-function mutation of proprotein convertase subtilisin/kexin type9 (PCSK9) gene results in familial hypercholesterolemia (FH) through degeneration of hepatic low-density lipoprotein (LDL) receptor. PCSK9 E32K is considered as gain-of-function mutation because HepG2 cells transient transfected PCSK9 E32K plasmid secretes 139% of PCSK9 protein compared with wild type. We found 9 patient with double heterozygous of LDL receptor gene mutation and PCSK9 E32K mutation, and their LDL-cholesterol levels ranged from 195 to 581 mg/dL. The most severe case was accompanied with large tendon xanthoma resembling homozygous FH as well as extreme hypercholesterolemia. These findings suggest that some additive hereditary factors are needed to exacerbate clinical features of PCSK9 E32K carriers.
