Niemann-Pick Disease

HIGH SEVERITY

A group of lysosomal storage disorders affecting lipid metabolism. Types A and B caused by SMPD1 deficiency (acid sphingomyelinase). Type C caused by NPC1 or NPC2 gene mutations affecting cholesterol transport. Types A and C have severe neurological involvement.

Diagnostic Methods

  • 1Genetic testing
  • 2Specialized biochemical tests
  • 3Imaging
  • 4Biopsy
  • 5Clinical evaluation
  • 6Specialist consultation

Prognosis

Variable; many rare diseases have limited treatment options but research is advancing rapidly. Early diagnosis crucial for optimal management.

Prevention

  • Genetic counseling
  • Carrier screening
  • Prenatal diagnosis
  • Newborn screening
  • Family planning

Research Status

Olipudase alfa (enzyme replacement) approved for ASMD (Types A/B). Miglustat approved for NPC. Cyclodextrin (HPBCD) intrathecal for NPC. Gene therapy trials ongoing.
