  • onset in adulthood (Fabry, Gaucher type 1, Pompe)
  • hepatomegaly and/or splenomegaly
  • hyperacusis
  • history of renal failure
  • skin rash/cutaneous lesions
  • large head circumference
  • macular "cherry red spot" on ophthalmoscopy
  • optic atrophy or retinitis pigmentosa on ophthalmoscopy
  • corneal clouding on ophthalmoscopy
  • fatigue
