A plain-language guide

Gaucher 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. Gaucher 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

Gaucher disease is an inherited (autosomal recessive) lysosomal storage disorder caused by deficiency of the enzyme glucocerebrosidase. The enzyme shortfall lets a fatty substance (glucosylceramide) build up inside immune cells called macrophages, which collect in the spleen, liver, and bone marrow.

Signs and symptoms

Thrombocytopenia

A low platelet count (thrombocytopenia) is a cardinal feature of Gaucher disease and can lead to easy bruising or bleeding.

Splenomegaly

An enlarged spleen (splenomegaly) is one of the most common signs of Gaucher disease, from buildup of Gaucher cells.

Hepatomegaly

An enlarged liver (hepatomegaly) is common in Gaucher disease and results from the same cell buildup.

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.

Imiglucerase

Enzyme replacement therapy with imiglucerase delivers a working copy of the missing glucocerebrosidase enzyme by intravenous infusion, the long-standing standard of care for Gaucher disease.

Used to help with: Gaucher disease.

Limited evidenceSource: PMID:28218669
The source text this rests on
“Disease-specific treatment consists of intravenous enzyme replacement therapy (ERT) using one of the currently available molecules (imiglucerase, velaglucerase, or taliglucerase).”

Eliglustat

Eliglustat is an oral substrate reduction therapy that inhibits glucosylceramide synthase, cutting production of the fatty substance that accumulates in Gaucher disease.

Used to help with: Gaucher disease.

Limited evidenceSource: PMID:26811686
The source text this rests on
“Eliglustat tartrate is a new substrate reduction therapy for GD, which acts as a specific and potent inhibitor of glucosylceramide synthase and can be administered orally.”
