Gaucher Disease: A Comprehensive Patient Guide

At a Glance

Gaucher disease is a rare genetic condition caused by an enzyme deficiency that leads to fatty substance buildup in the spleen, liver, and bones. It is classified into three types based on severity and neurological involvement. Standard treatments include enzyme replacement therapy (ERT) and oral medications to manage symptoms.

Welcome to your guide on Gaucher Disease. Whether you have just been diagnosed or are caring for a loved one, this resource is designed to help you understand the condition, navigate the medical system, and make informed decisions about your care.

What is Gaucher Disease?

Gaucher disease (pronounced go-SHAY) is a rare genetic disorder where your body is missing an enzyme needed to break down a specific type of fatty substance. This waste builds up in certain cells, causing them to enlarge and affect organs like the spleen, liver, and bones.

Common questions in this guide

What is Gaucher disease?
Gaucher disease is a rare genetic disorder where the body lacks a specific enzyme needed to break down fatty substances. This waste builds up in cells, causing enlargement of organs like the spleen and liver, and potentially damaging the bones.
What are the differences between the three types of Gaucher disease?
Type 1 is the most common form and typically does not affect the brain or nervous system. Types 2 and 3 are rarer forms that involve the nervous system and can be more severe, affecting prognosis.
How is Gaucher disease treated?
The main treatments are Enzyme Replacement Therapy (ERT), which involves infusions to replace the missing enzyme, and Substrate Reduction Therapy (SRT), which is an oral medication that reduces the production of the fatty waste.
How does the condition affect my bones?
Gaucher disease can weaken bones, leading to pain, increased fracture risk, or painful episodes known as bone crises. Protecting bone health through monitoring and treatment is a critical part of managing the condition.
How is Gaucher disease diagnosed?
Diagnosis involves genetic testing to identify specific mutations (like N370S or L444P) and blood tests to measure enzyme activity. These tests confirm the disease and help determine which type you have.
