    related resource Hypercholesterolemia, Familial
    Low Density Lipoprotein Receptor Mutation Database
    Other symbol(s) FHC, FH, HEFH, HOFH
    Main clinical features
  • HEFH characterized by a selective increase of LDL particles in plasma giving rise to tendon and skin xanthomas, arcus corneae and premature mortality from cardiovascular complications, a gene dosage effect and a more severe phenotype in homozygotes
  • Genetic determination autosomal dominant
    Related entries . HOFH, caused by two defective copies of the LDLR gene and thus having lack functional low density lipoprotein receptors (LDLRs), resulting in plasma LDL concentrations elevated on average sixfold above the normal range . characterized by early appearance of corneal arcus, cutaneous planar xanthomata over hands and extremities, tuberous xanthomata over elbows and tendinous xanthomata in the hand extensor and Achilles tendons
    Function/system disorder metabolism/lipoprotein-lipid
    Type disease
    Gene product
    Name lipoprotein, low density, receptor (LDLR)
    Remark(s)
  • thyromimetics such as GC-1 and KB2115 may represent promising cholesterol-lowering therapeutics for the treatment of homozygous familial hypercholesterolemia, a rare genetic disorder caused by a complete lack of functional LDLRs, for which there are limited treatment options because most therapeutics are only minimally effective (PMID: 23087171))
