Risk Factors

1Family history
2Genetic mutations
3Consanguinity
4Advanced paternal age
5Ethnic predisposition

Diagnostic Methods

  • 1Genetic testing
  • 2Clinical evaluation
  • 3Family history assessment
  • 4Specialized laboratory tests
  • 5Imaging studies
  • 6Biopsy (if applicable)

Prognosis

Homozygous: severe early cardiovascular disease, death by 20s without treatment. Heterozygous: CHD risk 20x normal, occurs 20-30 years earlier. With modern therapy, life expectancy approaching normal.

Prevention

  • Genetic counseling
  • Carrier screening
  • Prenatal diagnosis
  • Preimplantation genetic diagnosis
  • Family planning

Research Status

High-intensity statins, ezetimibe, PCSK9 inhibitors. Lipoprotein apheresis for severe cases. Lomitapide and mipomersen for HoFH. Early diagnosis and treatment prevent cardiovascular events. Cascade screening of family members.
