Plasma inducible degrader of the LDLR, soluble low-density lipoprotein receptor, and proprotein convertase subtilisin/kexin type 9 levels as potential biomarkers of familial hypercholesterolemia in children

The IDOL and PCSK9 plasma levels are significantly higher in FH children. Interestingly, sLDLR was associated with atherogenic dyslipidemia components. IDOL concentrations show a robust association with Lp(a) levels. To study the role of plasma biomarkers associated with LDLR expression in FH is warranted.
