Familial hypercholesterolaemia (FH) is an inherited disorder characterized by high concentration of plasma low‐density lipoprotein (LDL) cholesterol levels, as result of mutations in the LDL receptor (LDLR) that impair liver LDL clearance 1, 2, and less frequently by genetic defects in the apolipoprotein B‐100 (Apo B) or the protease PCSK9 3. The gene discussed is LDLR; the disease is familial hyperaldosteronism.
