what is familial hypercholesterolemia
Familial hypercholesterolemia (FH) is a diagnosis which refers to individuals with very significantly elevated low-density lipoprotein (LDL) cholesterol (LDL-C) or bad cholesterol. In heterozygous familial hypercholesterolemia (HeFH), an individual inherits a mutation (alteration) for FH from one (affected) parent.
