Alpha-galactosidase defect, one of the lysosomal storage disorders, with accumulation in various tissues.

X-linked but females get disease, so not correct to call them carriers.

Classically, “pain attacks”, affecting the extremities. In the abdomen, can mimic appendicitis. Due to accumulation in nerves. Since nothing to really see on examination, easily misdiagnosed as functional.

Other features:

• Renal impairment and failure.
• Angiokeratomas – a more specific feature, but not always present, and seen in other lysosomal disorders.
• Corneal changes
• Cerebrovascular and cardiac problems
