What is Fabry Disease?
Fabry Disease, is a genetic X-linked Lysosomal Storage disease. It is degenerative and interferes with the body's ability to break down specific fatty substances due to missing or insufficient quantities of an enzyme alpha-galactosidase A. This affects the organs of the body increasing the possibility in patients of heart attack, neuropathy, stroke, kidney failure, (frequently resulting in dialysis), and premature death. Fabry affects 1/40,000 people.
first descriptions of the condition were made simultaneously
by dermatologist Johannes

1898. It is sometimes referred to as Fabry-Anderson Disease.
Fabry Disease often presents itself during early childhood as pain and maybe overlooked by a GP and misdiagnosed as growing pains. Signs and symptoms vary from case to case even within the same family. However, not all cases of Fabry Disease are noticed and or experienced at such a young age. For a long time it was thought that only males suffered Fabry Disease and females were carriers. That is not the case and males and females can suffer equally. Fabry Disease is not a result of lifestyle choices.
- Neuropathic sensations (or pain) in hands/feet
- Headaches, vertigo / dizziness, fatigue
- Small raised dark-red dots on the body (called angiokeratomas)
- Intolerance to heat, sweating too little (condition called hyperhidrosis)
- Abdominal pain, vomiting & diarrhoea (not necessarily concurrent)
- Tinnitus (ringing sound in the ears), impaired hearing (sometimes hearing loss)
- Alterations in the eye, leading to clouding or whorling that can occur in the cornea (known as ‘Opacity of the Cornea’)
The disease is degenerative and patients typically develop symptons over time affecting the organs. Most frequently the kidneys, heart and brain depending on the individual mutation.
Fabry in New Zealand:
There are approximately 40 people diagnosed in New Zealand. Families are likely to have more than one family member with the disease and are subsequently impacted in each succeeding generation. Upon diagnosis a person can experience a range of emotions including shock, guilt, isolation, depression and fatigue.
Treatments currently available in New Zealand:
There is no cure for Fabry Disease. Treatments such as Enyzme Replacement Therapy, (ERT), or the oral treatment, Chaperone Therapy are funded in many OECD countries, (including Australia since 2004) but not in New Zealand. Treatment is not a cure. The goal of treatment is to modify symptoms of disease while stabilising the degenerative progression of disease, particularly to heart, lungs, brain and kidneys.
