A plain-language guide

Fabry disease

What is known, what is still uncertain, and what is actively debated, written plainly, and built only from published medical research.

Please read this first. This guide is a companion to your medical team, not a replacement, and it is not medical advice. Everything here is tied to published research. If something you expected is not here, it almost always means we have not mapped a source for it yet, not that it is unknown to medicine. Fabry disease is an early, growing map, so it will look incomplete on purpose: we would rather show less and have every line be something you can check than fill the page with claims we cannot stand behind. For anything about your own situation, your clinicians hold the full picture. How this guide is built and why.

What it is

Fabry disease is an inherited (X-linked) lysosomal storage disease caused by deficiency of the enzyme alpha-galactosidase A. The enzyme shortfall lets fatty material build up in cells throughout the body, progressively damaging the skin, kidneys, heart, nerves, and brain.

Signs and symptoms

Hypertrophic cardiomyopathy

Fabry disease can thicken the heart muscle (hypertrophic cardiomyopathy), which is a major cause of illness and death in the condition.

Left ventricular hypertrophy

Thickening of the heart's main pumping chamber (left ventricular hypertrophy) is a common cardiac feature of Fabry disease.

Stroke

Fabry disease raises the risk of stroke, including in younger adults, because of damage to blood vessels.

Cornea verticillata

Cornea verticillata is a whorl-like clouding pattern in the cornea of the eye and is a characteristic sign of Fabry disease.

Treatment and management

What the research describes, not a recommendation. Treatment decisions belong with your clinician.

This covers treatments that appear in the published research mapped here. Investigational and experimental therapies are not included, so their absence is a boundary of this map, not a sign they do not exist.

Agalsidase

Enzyme replacement therapy with agalsidase (alfa or beta) supplies the missing alpha-galactosidase A enzyme by intravenous infusion, slowing disease progression.

Used to help with: Fabry disease.

Limited evidenceSource: PMID:36832983
The source text this rests on
“Until a few years ago, treatment options for Fabry disease were limited to enzyme replacement therapy with agalsidase alfa or beta administered by intravenous infusion every 2 weeks.”

Migalastat

Migalastat is an oral medicine (a pharmacological chaperone) that stabilises and boosts the activity of the patient's own alpha-galactosidase A enzyme, for people whose mutations are amenable to it.

Used to help with: Fabry disease.

Limited evidenceSource: PMID:36832983
The source text this rests on
“Migalastat (Galafold) is an oral pharmacological chaperone that increases the enzyme activity of amenable mutations.”
